The Atlas of Minerals and Igneous and Metamorphic Rocks in Thin-section provides the geology student and geoscientist with a stunning new color atlas of the main rock-forming minerals and igneous and metamorphic rocks in thin-section. It showcases minerals in various settings and degrees of alteration and preservation to allow users to best identify their own specimens in practice. Chapter 1 highlights the distinctive characteristics used to identify different minerals. Building on this base, following chapters describe rock textures and types, summarising their petrogenesis within a plate tectonic framework. This book also includes insights into how information from photomicrographs can be studied using modern analytical methods, increasing understanding of geological processes. This Atlas is an indispensable reference textbook for all facilities that use a petrographic microscope, for professional geoscientists, and as an aid for any student studying minerals and rocks.
