A new fitting algorithm for petrological mass-balance problems
MJ Krawczynski, JL Olive - AGU fall meeting abstracts, 2011 - ui.adsabs.harvard.edu
We present a suite of Matlab programs aimed at solving linear mixing problems in which a
composition must be assessed as the convex linear mixture of a known number of end-
member compositions (eg mineral and melt chemical analyses). It is often the case in
experimental petrology that answering a geochemical question involves solving a system of
linear mass balance equations. Calculating phase proportions of an experimental charge to
determine crystallinity, comparing experimental phase compositions to determine …
