AGICO Print No. 29 Program ANI20BAS Purpose This program serves for on line measurement of the aniso- tropy of magnetic susceptibility (AMS) of rocks using the KLY-2 Kappabridge or the KLF-3 Susceptibility Meter. During measurement process, the susceptibility of the specimen is measured sub- sequently in 15 directions following rotatable design (for details see AGICO Print No. 1). Using the least squares method, the susceptibility tensor is fit to these measurements of the 15 directional susceptibilities and the errors of the fit are calculated. The results of the measurement, in the form of various parameters derived from the susceptibility tensor and orientations of the directions of the principal susceptibilities in various coordinate systems, are presented on the screen, can be printed using the line printer or written on the disk (into a sequential ASCII file). The tensor elements together with orientations of mesoscopic foliations and lineations can be also written on the disk (into standard AMS file which is binary random access file) from where they can be read in advanced processing. Setting up the MEASUREMENT OPTIONS After starting the program, the basic characterization of the program appears on the screen and the MEASUREMENT OPTIONS (with the default values) are displayed MEASUREMENT OPTIONS -> On Line Measurement/Manual Input (L/M): L KLY-2 Standard/KLY-2 Large Coil/KLF-3 (S/L/K): S Serial RS-232 Channel Port (1/2): 1 Correction for Demagnetizing factor (Y/N): Y Storing Tensors in Binary File (Y/N): Y Outprint of Results on Line Printer (Y/N): N Outprint of Results on Disk (Y/N): Y Input of Angles - Manual/from Disk/No (M/D/N): M To Leave Measurement Options press Insert Key Setting up the individual options is made in such a way that the horizontal arrow on the left hand side of the menu is moved (using arrows on the keyboard) towards the option under interest and the desired option is selected by simple pressing the cor- responding letter. When all the options are specified, one pres- ses the key INSERT and the measurement can start. The option On Line Measurement/Manual Input serves for decision whether to measure the AMS directly in the on line regime or to evaluate data measured earlier and recorded on paper manually. Mostly the L (On Line Measurement) selection is used. The option KLY-2 Standard/KLY-2 Large Coil/KLF-3 specifies the instrument used for measurement. The selection S indicates the KLY-2 Kappabridge with standard pick up coils, the selection L indicates the KLY-2 Kappabridge with large coils (for measurement of spheres 50 mm in diameter or cylinders 45 mm in diameter or cubes 38 mm in edge), while the selection K indicates the KLF-3 Susceptibility Meter. The option Serial RS-232 Channel Port enables the serial channel port to be selected. Mostly, channel No. 1 is used but, if this is occupied by an another equipment (e.g. by the mouse), channel No. 2 can be used. The option Correction for Demagnetizing factor gives one a possibility to correct the measured susceptibilities for the external demagnetizing factor of the specimen (the demagnetizing factor of the sphere is used for this purpose). This correction is useful only in very strongly magnetic specimens. Nevertheless, the correction can be formally made in all specimens, because it is negligible in weakly magnetic specimens. The option Storing Tensors in Binary File indicates whether to write the measured data on disk in the formatt of the standard AMS file (binary file, see Appendix 1). This file can be used as input file in advanced processing of AMS data using the ANISOFT program package. For this reason, it is recommended to select the option Y. The option Outprint of Results on Line Printer indicate whether to print or not the results, after measuring each specimen, on the paper using line printer. The option Outprint of Results on Disk indicates the possibility of printing the results on the disk in to a text file (having the extension APG) in the same format as that used by the line printer. The option Input of Angles - Manual/from Disk/No concerns the angular data measured in the field using geological compass. These data comprise the orientation angles of the specimen as well as the orientations of mesoscopic foliations and lineations. The most frequent is manual input of this data during measurement (selection M). In measuring large specimen collections, it is useful to prepare a special file with angular data (called the GEOLOGICAL DATA FILE, for its format see Appendix 1) prior to measurement and this data is read by the program directly. This makes the proper measurement rapid and comfortable (selection D). For those who measure unoriented specimens the selection N is advantageous, because the computer does not require any angular data. Testing Serial Channel RS-232 communication If the on line measurement is selected, the communication of the instrument with the IBM-PC type computer via serial channel RS-232 is tested and the message testing serial channel (timeout 10 s) appears on the screen. If there is something wrong in the communication, the following message appears on the screen #### RS-232 COMMUNICATION ERROR Current communication port: COM1 (or COM2) Switch off and on the instrument Check cable connections and port number and the MEASUREMENT OPTIONS appear on the screen again. In this case it is recommended to switch the instrument off and to check the connection of the instrument with the computer as well as to check whether the correct serial channel is set up. Setting up Orientation Parameters and Anisotropy Factors If the communication is O.K., the program asks for the orientation parameters specifying the way of oriented sampling. The scientists use different ways of sampling oriented specimens. In order to respect these differences we have developed such a software solution of the data transformation from the specimen coordinate system to the geographic, palaeogeographic and tectonic coordinate systems that it is controlled through the so called orientation parameters. In this way, any oriented sampling is possible. For definition of these orientation parameters and more details see AGICO Print No. 6. The program shows the set of current orientation parameters Orientation parameters P1 = value P2 = value P3 = value P4 = value Any changes [Y/N] ? If one enters N or free string, the shown parameters are used in the subsequent calculations. If one enters Y, new parameters are set up. Computer asks for inputting the P1, P2, P3, and P4 para- meters and displays them on the screen. These new parameters are written into a configuration file and are displayed, if the program is started again. The next step is specification of anisotropy parameters. Magnetic fabric can be visualized by the shape and orientation of the susceptibility ellipsoid. The eccentricity and shape of the ellipsoid can be characterized by conveniently chosen parameters derived from the principal susceptibilities (parallel to the axes of the susceptibility ellipsoid). Unfortunately, more than 30 parameters have been suggested for this purpose, even though 2 parameters are sufficient to characterize the eccentricity and shape. Some of them are listed in the enclosed Table. As it is not reasonable to present them all, our program selects 6 para- meters according to the demands of the user.

First, the set of the previously used parameters appear on the screen (Current anisotropy factors) together with the question Any changes [Y/N]. If one does not wish to change this set, one enters N or free string and the program prints Factors saved and continues in function. If one wishes to change this set, one enters Y and the program shows the table of factors from which one can select new set and asks Count of factors and one has to input the number of selected factors (in our case 6). Then one enters the number of factors and the name (abbreviation) of the factor delimited by comma. This is repeated until the whole set is introduced. After entering the last factor the program displays again the whole set and asks Any changes [Y/N]. In the case that one needs to do any change one has to repeat the whole procedure. If not, one enters N or free string and this procedure terminates. Opening data files If the measured data should be written on the disk (selection Y in the Outprint of Results on Disk option), a data file is open before the measurement of each collection of specimens. First Name of File (max 8 char) is input and then the path. If the opened file is not empty, the following selection follows [1] continue [2] overwrite [3] close the file Selection [1] is used, if one wishes to append the measured data to the data already present in the file. Selection [2] is used, if one wishes to overwrite the old data, and selection [3] gives rise to the termination of the program. Manual inputting auxilliary data Then, the name of the measuring person is input (Operator), Specimen Name (max 12 chars), Specimen Volume (CR retains this), and Holder Susceptibility (CR retains this). The default value of the Specimen Volume is 10 ccm for standard pick up coil of the KLY-2 Kappabridge and for the KLY-3 Susceptibility Meter and 65 ccm for the Large Coil pick up unit of the KLY-2 Kappabridge. Simple pressing ENTER confirms the displayed value. The default value of the Holder Susceptibility is 0, but after measuring the first specimen the input value appears and its confirmation is merely through pressing ENTER. If the measurement is made on the KLY-2 Kappabridge, the reading of DATA display (on the first range) is input (for example, -100), while the Total Susceptibi- lity of Vessel in the order of 10-6 is input, if the measurement is made on the KLF-3 Susceptibility Meter. If the angular data are input manually, the following inputs should be made. The most important are the orientation angles Azimuth, Dip/Plunge of Specimen. The first angle is the azimuth of the fiducial mark on the specimen (mostly is is the strike of the mark if this is drawn horizontally or azimutn of the dip if the mark is drawn as the dip line). The second angle is dip of the fiducial line if block specimens are sampled or plunge of the cylinder axis if a cylindrical specimen is drilled in the field using portable drilling machine. The next input is Code for the First Foliation and Lineation (ENTER -> no input). The two- character code characterizes the measured mesoscopic foliation and lineation (see table in the Appendix 2). If only foliation exists, the second character in the code is 0. Then, Azimuth of dip and Dip of foliation 1 are input delimited by comma, i.e. the angles are azimuth of the dip (or strike if the orientation para- meter P4 is 90), dip of the first mesoscopic foliation. If the second character of the code for the first foliation is not zero, also Trend and Plunge of Lineation 1 are input.The last input is Code for the Second Foliation and Lineation (ENTER -> no input). The two- character code characterizes the second measured meso- scopic foliation and lineation (see table XX). If only foliation exists, the second character in the code is 0. Then, Azimuth of dip and Dip of foliation 2 are input delimited by comma, i.e. the angles are azimuth of the dip (or strike if the orientation para- meter P4 is 90), dip of the first mesoscopic foliation. If the second character of the code for the first foliation is not zero, also Trend and Plunge of Lineation 2 are input. Proper Measurement After appearing the message FIND MEASURING RANGE, PRESS one should mount the specimen into the specimen holder in the first measuring position (see Appendices 4, 5) and measure it manually (following the KLY-2 Instruction Manual). Repeat this measurement, changing the measuring ranges, so long until the measured value (DATA on the instrument display) is between 1000 and 2000. This enables the most sensitive measurement of the AMS to be done. If the most convenient measuring range is found, one presses CR and the following message appear MEASURE IN 15 DIRECTIONS ANY KEY BUT -> STARTS MEASUREMENT KEY -> STARTS REPEATED MEASUREMENT When ready to measure, one presses CR, waits for the beep from the computer (indicating that the instrument is ready to measure) and inserts the specimen oriented in the first position into the measuring coil. After the specimen is measured, the instruments beeps and one takes the specimen out of the coil. The results appear on the screen as shown in the following example 1 6 1789 where 1 is the position number, 6 is the range number (not range multiplication factor) and 1789 is the DATA reading. Then, one changes the specimen position in the holder, presses CR and measures the specimen in the second position in exactly the same way as in the first position. This procedure is repeated until the specimen is measured in all 15 measuring positions. If one feels that any measurement was wrong for some reason, one can re-measure the just measured position by pressing R and subsequent repeated measuring. After the measurement of the specimen in all the 15 posit- ions is finished, the partial results appear on the screen enabling the measurement accuracy to be evaluated.

The data RESIDUALS represent the deviations of the measured and fit data. After fitting the susceptibility ellipsoid to the measured data using the least squares method, the susceptibility in each measuring direction is calculated from the fit tensor and subtracted from the measured value; this is the residual. The residuals are the lower the higher is the measuring accuracy and better fit. Ideally, the residuals are as low as the measuring errors of individual directional susceptibilities. STD. ERROR is the mean value of the absolute values of the residuals. The quality of the measurement can be evaluated also from the values of ANISOTROPY TEST and CONFIDENCE ANGLES. The ANISOTROPY TEST values are the values of the F-test for anisotropy/isotropy and for triaxial/rotational prolate and for triaxial/rotational oblate ellipsoids. If the left value is higher than 3.48 then the differences between the principal susceptibilities determined by measurement compared to measuring errors are great enough that the specimen can be considered anisotropic from the statistical point of view (on the 95 % level of significance). If the central and right values are higher than 4.25, then the ellispoid is triaxial. The CONFIDENCE ANGLES values are those of the angles defining the statistical accuracy of the determination of the directions of the individual principal susceptibilities on the 95 % level of significance (for more details see AGICO Print No. 1). Useful are also the values of the ANISOTROPY FACTORS. Namely, in the case of very weak anisotropies (e.g. P < 1.01) it is diffucult to obtain low confidence angles. If one is satisfied with the accuracy one presses the selection CONTINUE/PRINT, otherwise one presses CORRECTION and corrects the insufficiently precisely measured directional susceptibilities. The correction is made in such a way that one adjusts the specimen in the holder in the position to be re-measured, input the position number after the message Position (0 -> No Correction) and re-measures the position. One can re-measure any number of positions. After correcting one inputs 0 and the above partial results re-appear on the screen. One can proceed with CONTINUE/ PRINT or with CORRECTIONS. If so many measurements are wrong that it is better to re-measure the specimen in all positions one presses KILL MSMENT and re-measures the whole specimen. If one finds that the measurement is wrong and manually input angular data is also wrong, one presses KILL ALSO DATA and inputs the angular data again and re-measured the whole specimen. If the precision is acceptable, one prints the results (on the paper or into the file on disk according the the options selected in the MEASUREMENT OPTIONS). An example is shown in the next page.

Appendix 1. Structures of Data Files The program works with, among others, three important types of data files. The first one is classical sequential ASCII file, whose structure does not need comment.

Note : The orientation of mesoscopic foliation should be measured in terms of azimuth of dip and dip or strike and dip and this is indicated by the orientation parameter p4 (see the section 5 Orpar). The azimuth of dip or strike should be measured as angles ranging from 0 to 360 degrees (not from zero to 180 degrees) and they are recorded in the geological data file as measured. However, in the standard anisotropy file they are recorded in terms of azimuth of the dip and dip regardless of the way of measurement. This is made automatically by the program and this must be kept in mind in the later manipulation with the data. (One should not be surprised seeing the same angle data recorded differently in the geological data file and in the standard AMS file.) Appendix 2. Selection of Coordinate Systems In this program, the orientations of magnetic foliation and magnetic lineation can be presented not only in the standard geographical coordinate system, but also in the so-called palaeo- geographical system (after rotation of the mesoscopic foliation under consideration into the horizontal position about the corresponding lineation) or in the so-called tectonic coordinate system (mesoscopic lineation and foliation are the coordinate axes). The program can work with up to 2 pair of mesoscopic foliation and lineation which are described by a two-character code. The first character of the code describes the foliation, while the second character describes the lineation (for the proposal of the codes see the enclosed table). For example, the code characterizing the existence of metamorphic schistosity and mineral alignment lineation is SA. If only the foliation and no lineation exist, the second character in the code is zero. For example, the system characterized by the bedding only has the code B0.

Inputting geological locality data The inputting of the locality data is not compulsory. The ANISOFT package of programs for advanced AMS data processing does not work with the locality data. These data serve only for storing the locality geological chracteristics on the disk. In inputting the locality geological data, the following data are asked for. NAME OF LOCALITY (max 16 characters, ENTER means no data) (This is the literary name of the locality, it serves only as a note characterizing the locality location, etc.) LOCALITY GEOGRAPHICAL LONGITUDE (DECADICAL EXPRESSION) LOCALITY GEOGRAPHICAL LATITUDE (DECADICAL EXPRESSION) both in the format xxxx.xx (These data are input as decadic expressions, not using minutes and seconds.) ROCK TYPE (max 4 characters) STRATIGRAPHY (max 4 characters) LITHOSTRATIGRAPHY (max 4 characters) REGIONAL (max 4 characters) (These data are recommended to be input as 3 character codes; their purpose is to characterize geologically the locality investigated, they are not used in further calculations.)
