A Geoscientist studies the nature, composition and structure of the earth to increase scientific knowledge, locate materials and minerals, and to provide advice on the extraction of minerals, environmental consequences and rehabilitation of land post-mining activity.
Geoscientists commonly specialise in a particular area, whether it be as a Field/Exploration Geologist, Geochemist, Mineralogist, Geomorphologist, Hydrogeologist, Mine Geologist, Paleontologist or a Structural Geologist.
Geoscientists in the minerals industry may perform the following tasks:
- Explore specific areas of the earth to determine its structure and the types of rocks or minerals that exist
- Study rock core, cuttings and samples
- Study geostatistics and sampling theory
- Undertake ground magnetic and gravity surveys
- Examine specimens in the lab using optical, x-ray and electron microscopes
- Assist in determining the economics of extraction
- Advise on geological suitability for structures
- Contribute to environmental assessments
- Use computers to integrate and interpret data
- Prepare mathematical models to describe processes and predict future situations
- Prepare geological reports
- Supervise and coordinate the work of field officers
