Rock Classification
Rock Classification is a fundamental skill in geology where professionals organize and identify different types of rocks based on their characteristics. It's like sorting books in a library, but for rocks. This knowledge helps geologists determine what resources might be present in an area, assess construction site stability, or evaluate mining potential. When you see this term in resumes, it indicates that the candidate knows how to identify and categorize rocks using standard methods like the USGS (United States Geological Survey) system. Similar terms you might see include "Lithological Classification" or "Rock Type Analysis."

Senior Level Questions
Q: How would you train junior geologists in rock classification methods?
Expected Answer: A senior geologist should discuss creating systematic training programs, hands-on field experience, quality control measures, and methods to ensure consistent classification across team members.
Q: How do you handle complex geological sites with multiple rock types?
Expected Answer: Should explain their approach to systematic sampling, documentation methods, use of field tools, and how they organize and present findings to non-technical stakeholders.
Mid Level Questions
Q: What methods do you use to ensure accurate rock classification in the field?
Expected Answer: Should describe basic field testing methods, use of reference materials, documentation procedures, and when to collect samples for laboratory analysis.
Q: How do you document and report rock classification findings?
Expected Answer: Should discuss field notes, photography, sampling procedures, and how they prepare reports that non-geologists can understand.
Junior Level Questions
Q: What are the three main types of rocks and how do you identify them?
Expected Answer: Should be able to explain the basic differences between igneous, sedimentary, and metamorphic rocks in simple terms and describe basic identification methods.
Q: What tools do you use for basic rock classification in the field?
Expected Answer: Should mention basic field tools like hand lens, rock hammer, streak plates, and reference charts, explaining how each is used.
