petrographic
Stone structure analysis
Petrographic describes the study and classification of rocks, especially through microscopic examination of thin sections.
The term appears in technical geological contexts: petrographic analysis, petrographic microscope.
A petrographic study reveals a rock's mineral composition, texture, and formation history.
