Synthesized from method descriptions across 14 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Model-based interpretation of solute exports and carbon partitioning during shale weathering in a mountainous hillslope (2026), Water Resources Research. Implementations in other papers (listed below) may differ.

1. Collect discrete solid phase samples
   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
   Equipment: soil sampling equipment, core drilling equipment
2. Analyze solid samples
   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
   Equipment: X-ray diffraction equipment, TOC analyzer, nitrogen analyzer

Typical Equipment

• X-ray diffraction equipment
