Measurement of ¹⁴C content to distinguish between modern plant-derived and ancient shale-derived organic carbon sources

The most recent time during the last glacial period when ice sheets were at their greatest extent

Computational simulation of avalanche flow physics to predict runout distance and impact parameters

Temporal correlation of rock units based on fossil content

Forward movement of ice sheets that leave behind terminal moraines and other glacial deposits

Late Cretaceous geological time intervals

Linear scratches and grooves carved into bedrock by glacial ice movement

Evidence of marine or estuarine conditions during sediment deposition based on presence of marine taxa

Cycles of sea level rise and fall that control sediment deposition patterns in marine basins

Reconstruction of past glacier extents and ice thickness using geomorphic evidence and numerical modeling
