petrologist
Studies stone composition
A petrologist is a scientist who studies rocks—their origin, composition, structure, and the processes that form and transform them.
Petrology is a branch of geology, and petrologists typically specialize in igneous, sedimentary, or metamorphic rocks.
The petrologist analyzed the volcanic samples to determine the magma's cooling history.
