Method synopsis
Depth-resolved sampling and analysis of subsurface materials for mineralogical composition, organic matter content, and spatial distribution of weathering products from soil through bedrock.
Synthesized from method descriptions across 4 papers using this protocol.
Procedure from a recent peer-reviewed implementation
Carry out discrete solid phase sampling and analyses down to a depth of 10 m to map the distribution of bulk biogeochemical properties and characterize the spatial extent of the weathering front
Quantities: Samples to 10 m depth, spacing between samples progressively increasing at greater depths, intervals ranging from 0.1 to 3 mDuration: Sample collection campaign described in Stolze et al. 2023b; Wan et al. 2021Conditions: Field sampling conditions
Analyze solid samples for bulk mineralogy via X-ray diffraction, solid-associated total organic carbon (TOC), and total organic nitrogen across soil, saprolite, and bedrock layers
Quantities: All collected solid samples across three layersDuration: Laboratory analysis periodConditions: Standard laboratory analytical conditions
