DIGITAL COMPUTER PROGRAMS FOR PALEOMAGNETIC RESEARCH.
Abstract
This report describes three programs written in Fortran IV for the IBM 7090 and 7094 digital computers. Their purpose is reduction and statistical analysis of remanent magnetization data obtained from oriented rock specimens used in paleomagnetic research. The first program (magnetometer program) computes, for each oriented specimen, the declination, inclination, and intensity of remanent magnetization, using as input the component directions and intensities obtained with an induction ('spinner') magnetometer. An estimate of the precision of angular measurement is also obtained, and in the case of deformed rocks, the magnetization is obtained both in present geographic coordinates and in what may be surmised to have been the original coordinates. The second program (Fisher statistics program) uses the output from the first and calculates the mean magnetization directions of groups of specimens, the appropriate statistical parameters, and the paleomagnetic pole position corresponding to each group. The third program (virtual magnetic pole program) calculates the mean poles from groups of paleomagnetic poles, together with the appropriate statistics for each. (Author)
