Fortran IV program for processing geochemical sediment data, 34 p.A general computer program has been written to process geochemical data resulting from the analysis of up to 34 trace elements per sample. This program will: 1. Produce a table for direct inclusion in formalreports. The table contains the map number and field number of the geochemical samples, the corresponding elemental values and a table giving descriptive data about the sample. Prior to printing, the samples are arranged according to map number for easy correspondence between the table of values and to the geochemical map. 2. Compute the average value for each element, normally and lognormally. 3. Compute the standard deviation for each element, normally and lognormally. 4. Compute the threshold value for each element, normally and lognormally. 5. Compute the anomalous concentrations for each element, normally and lognormally. 6. Draw lognormal, or standard histograms for each element. All geochemical samples taken by the Alaska Division of Mines and Geology during the summer of 1968 and 1969 were processed by this program or a modification of the program. The program can be modified to enable production of automatic maps and tables of anomalous samples.
