Abstract

Cores from this system illustrate typical lithology and structure of sediments in these environments. Deposits are late glacial and postglacial in age. The canyon and fan deposits can be identified as related because of the laterally continuous contacts between postglacial and glacial sediments, distinctive mineral and faunal compositions, and rhythmically interbedded turbidites and hemipelagites. Homogeneous silty clay beds dominate canyon deposits, which also contain more organic material and glauconite and show more evidence of slumping than do the fan deposits. The fan deposits contain numerous, thick, coarse, well-sorted sand and silt beds that exhibit well-developed internal structures. Distinctions can also be made between deposits from different parts of the fan.
