Non-clay and clay mineral compositions of Western North Atlantic sediments

The data set represents an extensive collection of the sediment non-clay and clay mineral compositions, based on quantitative X-ray diffraction (qXRD) data. Mineral compositions are included from 90 bedrock or large ice-rafted clasts from around the Western North Atlantic. Sediment samples on the < 2mm sediment fraction were obtained using the whole pattern approach to mineral identification from the same area that include cores and sites collected on CCS Hudson and Marion Dufrense expeditons. Several cores include one or more detrital carbonate Hudson Strait Heinrich events.
