Abstract

PRACTICAL ASPECTS OF USE OF SELECTED METHODS IN DETERMINING MODAL MINERAL COMPOSITIONS IN PERIDOTITE XENOLITHSAbstract. In scientific literature, there are several methods, estimating modal mineral composition in peridotite xenoliths. The main techniques are focused on: 1) traditional microscopic analyses (point counting), 2) statistical recalculations of bulk-rock, and mineral chemical compositions, 3) digital image processing. The above techniques differ from each other in sample preparation, amount of material required for analysis, data acquisition time etc. Based on comparative studies, the most effective method for determination of mineral composition in peridotite xenoliths has been chosen.
