petrographyrelated
Petrography-related refers to topics connected with petrography, the study of rocks through microscopic description and analysis. Petrography itself focuses on identifying minerals, textures, and interrelationships in rock samples, usually by examining thin sections under a polarized light microscope. The aim is to classify rocks and reconstruct their formation and post-formational history. The term encompasses a range of subfields and methods that address different rock types and geological questions.
Subfields include igneous petrography (mineral assemblages and textures of igneous rocks), sedimentary petrography (parses grains, matrix,
Common methods include optical microscopy of thin sections, point counting for modal analysis, electron microprobe and
Applications span geology, mining, petroleum geology, archaeology, and environmental science. Petrography supports rock classification, provenance studies,
