Bibliography of fine-grained siliceous deposits Bibliography of fine-grained siliceous deposits
This bibliography was compiled under the auspices of the International Geologic Correlations Project's (IGCP) Research Group 115, "Siliceous Deposits of the Pacific Region"; IGCP is sponsored by UNESCO and the International Union of Geological Sciences (IUGS). Research Group 115 was originally proposed to IGCP in 1974 by Professor Azuma Iijima, University of Tokyo, and is now headed by...

Clay mineralogy, fine-grained sediment dispersal, and inferred current patterns, lower Cook Inlet and Kodiak shelf, Alaska Clay mineralogy, fine-grained sediment dispersal, and inferred current patterns, lower Cook Inlet and Kodiak shelf, Alaska
Because lower Cook Inlet and Kodiak shelf are being explored and developed for their petroleum resources, it is essential for environmental reasons to understand the sediment dispersal routes and current patterns. The Susitna River flows into upper Cook Inlet and is the source of clay minerals in Holocene deposits found in western lower Cook Inlet. The Copper River, in the northern Gulf...

Episodes of Aleutian Ridge explosive volcanism Episodes of Aleutian Ridge explosive volcanism
Earlier workers have overlooked deep-sea bentonite beds when unraveling the Cenozoic volcanic history of an area. In the North Pacific, identification of Miocene and older volcanic episodes is possible only if both altered (bentonite) and unaltered ash beds are recognized. Our study, which includes bentonite beds, shows that volcanism on the Aleutian Ridge and Kamchatka Peninsula has...
