Quick Summary

Core logging is a field technique used in mineral exploration to analyze geologic formations penetrated by a drill hole. When a drill hole is made using coring techniques, the extracted rock core provides a visual record of the formations and rock types encountered. Geologists carefully describe, or log, the core to determine the location and kinds of rock and minerals present, as well as structural features and rock strength. This detailed description, or log, forms the basic data for geologic analysis, interpretation, and resource calculations. Core logging is a specialized skill requiring careful observation and accurate recording. Geophysical logging can also be performed without collecting a core.12
