FRACTAN: A Computer Code for Analysis of Clusters Defined on the Unit Hemisphere.


PB240685

Publication Date 1975
Personal Author Shanley, R. J.; Mahtab, M. A.
Page Count 54
Abstract The report presents a computer code that has been developed for isolating naturally occurring clusters of data plotted on the unit hemisphere and testing these clusters against a probability distribution which admits elliptical symmetry about its mean. A listing of the computer code is provided along with an example output illustrating the delineation and analysis of clusters in fracture orientations measured in a porphyry copper deposit.
