FIELD GUIDE FOR ROCK CORE LOGGING AND FRACTURE ANALYSIS

• 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

This field guide helps you think on your feet in the field. Use it to 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; and reduce log editing time. Double-sided, plastic-coated guide is clear, consistent, and concise. A list of general rock names is included for helping identify common rock types and schematic is provided for helping properly label the rock core box and place the rock core. 8.5x11
