WebThin Section Preparation and Analysis This analysis includes a basic petrographic description, including visual estimation of grain size, sorting, porosity and mineral abundances, fabric, rock classification, porosity varieties and abundances. Two (2) color photomicrographs of each sample with complete written descriptions are included. WebA manually operated point counter for thin section analysis is described. The machine is sturdy, inexpensive, and easily operated. Its precision has been tested by analyzing 47 thin sections in duplicate and computing the analytical error, or standard deviation of a single analysis, from the observed variance of the differences.
