Petrologists also include the principles of geochemistry and geophysics through the study of geochemical trends and cycles and the use of thermodynamic data and experiments in order to better understand the origins of rocks.
Moderni petrolozi također uključuju principe geokemije i geofizike kroz proučavanja geokemijskih trendova i ciklusa te rabe termodinamičke podatke i eksperimente za bolje razumijevanje porijekla stijena.
