Description

Collection of continuous vertical and horizontal drill cores from shale bedrock to characterize sulfur speciation changes with depth and weathering extent. Combines drilling techniques with subsequent XANES analysis.

Typical Equipment

• track-mounted drill rig
• 0.14-m diameter ODEX drilling bit
• hand drill
• 24.5-mm diameter diamond drilling bit

Output Measurements

• sulfur speciation profiles
• weathering gradients
• pyrite oxidation state
