Plunge
Plunge is a basic measurement term used in geological surveying and mining to describe how steeply something goes down into the ground. Think of it like measuring the steepness of a slide at a playground, but for rock layers, mineral deposits, or drill holes. When someone mentions "plunge" in their resume, they're typically talking about their experience in measuring and recording these angles, which is important for planning mining operations, understanding rock formations, or setting up drilling projects. Similar terms you might see include "dip," "inclination," or "pitch."

Example Interview Questions
Senior Level Questions
Q: How do you ensure accuracy when measuring plunge angles in challenging terrain?
Expected Answer: A senior surveyor should discuss multiple measurement methods, error checking procedures, and how to adapt to different field conditions. They should mention both traditional and modern digital tools.
Q: How do plunge measurements factor into mine planning?
Expected Answer: Should explain how plunge measurements help determine drilling directions, predict resource locations, and influence safety considerations in mining operations.
Mid Level Questions
Q: What tools do you use to measure plunge, and how do you maintain them?
Expected Answer: Should be able to discuss various measurement tools like clinometers, digital survey equipment, and explain basic maintenance and calibration procedures.
Q: How do you document plunge measurements in the field?
Expected Answer: Should describe recording methods, field notation systems, and data management practices, including both paper and digital documentation.
Junior Level Questions
Q: What is plunge and why is it important in geological surveying?
Expected Answer: Should be able to explain that plunge is the vertical angle of geological features and its basic importance in understanding rock structures and planning work.
Q: Describe the basic process of taking a plunge measurement.
Expected Answer: Should explain the fundamental steps of using basic measurement tools and recording readings accurately.
