Title

Improving the RockJockML Program Functionality

Abstract

The RockJockML program performs full-pattern fitting of powder X-Ray diffraction (XRD) patterns of whole rocks and sediments to determine mineral composition. It displays the XRD peaks and allows the user to select different standard minerals with XRD patterns in a database, and the program attempts to mimic the sample pattern with a linear combination of the selected standards.  However, some knowledge of which minerals are likely to occur together is necessary to perform a rapid and accurate analysis.  I am creating functions that provide recommendations of which minerals to select based on both XRD peak locations and known mineral localities.
