Clay mineralogy of the Lower Cretaceous deep-sea fan, Deep Sea Drilling Project Site 603, lower continental rise off North Carolina.

Abstract

The clay mineralogy is dominated by smectite in most intervals, and by illite in samples from intervals of high sand input. Different intervals of high sand input are enriched in kaolinite. Kaolinite and illite levels do not correlate in this sediment, indicating that the input of each clay type was independent and represents either a different provenance or a different depositional mode.-from Author
