The duties of a core analyst are to analyze the components of the earth, such as water, rock, or minerals. These responsibilities include collecting samples and testing them in specialized labs. After testing, they record the data and analyze the samples for specific properties. For example, a core analyst who works in oil extraction or water exploration may collect samples from a potential well and determine the composition of the soil or rock and provide advice related to extracting the material wealth of the land. Additional responsibilities are to manage and maintain equipment in the labs.
