Geologist
From Wookieepedia, the Star Wars wiki.
A geologist was a student of geology. Jedi geologists were a variation of this, working through the Agricultural Corps.
Geologists mapped geology of planets and charted mineral resources.
In 40 ABY, a geologist and a minerals engineer ran some scans of the planet Mandalore over terrain bombarded by Yuuzhan Vong. Within craters, outcrops from a lode of beskar, Mandalorian iron, were exposed, turning the economy of Mandalore around.
