Use of Polymethyl Methacrylate in preparing Thin Sections of Recent Sediments

Abstract

IN the examination of Recent sediments it is necessary to identify accurately the mineral grains and lithic fragments which make up the deposit. Compositional properties such as the quantity and type of quartz, feldspar, calcite and the lithic, or rock, suite are keys to the proper interpretation of source and dispersal of a sediment. Such properties as diagenetic alteration of grains, mineral inclusions and specific rock types can be determined only by optical study of specially prepared petrographic thin-sections.
