In 2152, the  was dispatched to Xantoras to extract a team of three spelunking Denobulan geologists. While navigating the caverns and choosing which way to go, Malcolm Reed noticed a cluster of crystals and decided "If I was a geologist, that's the way I'd go."

Kirk argued that he felt Carstairs wasn't right for the job because he was an ensign on his first tour of duty, and that Rawlins was his chief geologist. M-5, however, chose Geologist Carstairs due to the fact that he had served on merchant marine freighters in the region and that he had once visited planet on a geology survey for mining company. ()

In 2268, speaking to Senior Geologist  about joining a survey party, Captain Kirk described the Kalandan outpost planet as a geologist's dream. D'Amato agreed, stating that an "opportunity to explore so young a planet is an incredible bit of luck." Kirk bolstered the offer by stating that following his analysis, "you'll have a report to startle the Fifth Interstellar Geophysical Conference." ()

Sometime before 2369, Nella Daren lead a team of geologists in a study of the plasma geyser on Melnos IV. ()

In 2370, the  visited Atrea IV at the request of the Atrean government to assist in averting a natural disaster. Two geologists from the planet, Juliana and Pran Tainer came aboard the Enterprise-D to discuss the situation of the solidification of the planet's molten core. ()
