Without you, the geologist is just a person with a hammer and a guess.

The work splits roughly into two scenes: the field and the lab (or the office). In the field, you might be at a mining exploration site, an oil and gas drilling operation, a construction site, or an environmental assessment area. In the lab, you're processing what you brought back. The split between the two depends heavily on the industry you work in and the specific company that hires you. A technician at a remote mining exploration camp might spend 80% of their time outdoors. A technician at a core analysis lab in Houston might spend 95% of their time indoors, handling cylindrical rock cores. The title is the same, but the day is completely different.

Let's walk through the core responsibilities, because they're more varied
