geologist's
Earth scientist's possession
Geologist's is the possessive form of geologist—a scientist who studies the earth's structure, composition, and history.
The possessive indicates something belonging to or associated with such a scientist: a geologist's hammer, the geologist's field notes, from a geologist's perspective.
