X-ray diffraction | Clays and Minerals

Precise identification of clay minerals is the first step in any clay mineral analysis, and we base our identifications on years of experience of the interpretation of diffraction patterns from clay minerals and their responses to various ancillary treatments.

Clay Minerals

Clay minerals are an important group of minerals because they are among the most common products of chemical weathering, and thus are the main constituents of the fine-grained sedimentary rocks called mudrocks (including mudstones, claystones, and shales).

THE CLAY MINERAL GROUP - Amethyst Galleries

Clay minerals are divided into four major groups. These are the important clay mineral groups: The Kaolinite Group This group has three members (kaolinite, dickite and nacrite) and a formula of Al2Si2O5(OH)4.The different minerals are polymorphs, meaning that they have the same chemistry but different structures (polymorph = many forms).
