Sentences with phrase «geochemical analysis»
Geochemical analysis refers to the study of the chemical composition and characteristics of rocks, minerals, and other natural materials found in the Earth's crust. It involves analyzing samples to understand processes like mineral formation, element distribution, and the history of Earth's geological and environmental conditions. Full definition
