Latin, early 18th century

Why this word?

From the Greek for “stone,” “lithology” concerns the study of the physical nature of rocks. These physical characteristics include mineral composition, color, texture, and size. When you were in school and you learned how to identify the difference between sandstone and limestone, for example, that was lithology. Lithology is important to many fields that involve breaking through layers of rock and sediment, including archaeology and all types of constructions and mining.
