The job duties of an entry-level exploration geologist involve examining a location to determine if it contains natural resources. Your responsibilities in this career include working in the field to perform analysis for mining, oil, gas, or other resource extraction industries. An entry-level exploration geologist uses specialized equipment to collect mineral samples at the target location. You sometimes return to a laboratory to perform sample analysis and record and report your findings to your employers or clients. You may also make assessments in the field during an exploratory drilling operation to save time. Entry-level geologists typically work under a senior geologist.
