Method synopsis

Standardized preparation of rock samples for weathering experiments including crushing to uniform size, ultrasonication cleaning to remove fines, and oven drying. Designed to expose fresh surface area while maintaining uniform grain size for column packing.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Contact Metamorphism of the Mancos Shale: Impacts on Solute Release and Weatherability in the East River Valley, Gothic, CO (2018). Implementations in other papers (listed below) may differ.

1. Sample collection and preparation
   Four samples were collected from the East River watershed: weathered and unweathered unmetamorphosed Mancos shale (WU and UU) from lower reaches where river banks are wide and meandering, and two metamorphosed samples (UM1A and UM1B) from upper reaches in close proximity to tertiary aged granitic intrusions. All samples were crushed to a median size of approximately 2.5 x 2.5 cm to expose fresh surface area and minimize differences in column packing material size.
   Quantities: Four samples total: 2 unmetamorphosed (1 weathered, 1 unweathered) and 2 metamorphosed samplesDuration: Not specifiedConditions: Samples collected from outcrop locations in East River watershed
   Equipment: crushing equipment
2. Sample cleaning and drying
   Crushed samples were placed in Nalgene bottles with deionized water in an ultrasonicator bath for five minutes, the fluid was decanted to remove fines, and the samples were oven dried at 50°C for 48 hours.
   Quantities: All four samples processedDuration: 5 minutes ultrasonication, 48 hours dryingConditions: 50°C oven temperature
   Equipment: Nalgene bottles, ultrasonicator bath, oven
