Field Guide for Rock Core Logging and Fracture Analysis

This Field Guide helps you to think on your feet in the field:

• Improve the accuracy of your rock core logs
• Reliably measure core recoveries: Total, Solid and Modified
• Measure Rock Quality Designation (RQD) with QA/QC steps
• Prepare consistent descriptions
• Analyze rock as the drilling program progresses
• Quickly characterize fractures and their distribution
• Build the geologic framework from boring to boring
• Identify general rock types
• Obtain guidance for placing and labeling cores in the box
• Reduce log editing time

Ensure that your rock core descriptions are clear, consistent, and concise. Follow common procedures for identifying natural fractures, calculating Total, Solid, and Modified Core Recovery and measuring Rock Quality Designation (RQD). Sharpen your observational skills for describing and characterizing rock core, stratigraphy and secondary rock weathering.

The back side of the chart includes a Fracture Characterization Guide for analyzing bedrock fractures from any size rock core. Help yourself to identify general rock types along with properly labelling the rock core box and placing the rock core.
