Streambed Sediment Data for Missouri and Niobrara Rivers, 2015

Four supplemental data sets describe deltaic sand deposits at the head of Lewis and Clark Lake, Nebraska-South Dakota, investigated for suitability as a proppant feedstock. Data includes core lithology descriptions in CSV, apparent resistivity profiles in PNG, laboratory reports on particle size and shape in PDF, and sample photomicrographs in JPEG. The dataset was authored by Brent M. Hall of the United States Geological Survey and relates to a 2015 investigation.

Use Cases

• Assess proppant feedstock suitability based on particle size and shape statistics.
• Analyze subsurface sediment structure based on capacitively coupled resistivity profiles.
• Characterize core lithology and texture from direct-push core samples.
• Evaluate sediment crush resistance at a stress level of 34.5 MPa.
• Perform visual grain analysis using photomicrographs with a 0.5-mm scale reference.

Strengths

• Includes multiple data modalities: tabular core descriptions, geophysical images, laboratory PDFs, and photomicrographs.
• Laboratory tests include a specific crush-resistance stress level of 34.5 MPa (5,000 lbf/in2).
• Photomicrographs include a standardized 0.5-mm diameter pencil lead for scale.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
