Study on the Preparation Method of Fluorescent Rock Thin Sections Made from Non-fluorescent Materials

Abstract

Canadian gum, epoxy resin, and emery are used in the production of general rock thin section materials. These materials have fluorescence, so it is not possible to make fluorescent thin sections. The use of other colloids or transparency is not good, because the use of abrasive emery will also lead to the specimen having fluorescence, which cannot be selected. At present, 502 is usually used to make fluorescent sheet adhesive in China, but the colloid is soluble in water and the colloid is not impact-resistant. During sample preparation, it cannot be used for a long time by water grinding, only dry grinding or oil grinding. The samples of water grinding are susceptible to moisture and scratches, so the rock sheet cannot be preserved for a long time, which seriously affects the efficiency and quality of production. In recent years, the team has come up with a variety of materials and methods to make fluorescent rock-thin sections through repeated trials and achieved good results.
