Printing Office) 56-57 https://doi.org/10.2973/dsdp.proc.5657.127.1980 887-893 Approximately 20 meters of the section near the bottom of Hole 436 was "unfossiliferous," overlain by middle Miocene mudstone with siliceous microfossils and underlain by Cretaceous chert. Therefore we attempt to determine the age of these pelagic clays on the basis of the ichthyoliths. Site 436 is at 39°55.96'N, 145°33.47'E, in a water depth of 5240 meters. The cores investigated here (Nos. 39 and 40) are from 359.5-378 meters below the sea floor. In addition, we studied one sample from Core 41, containing Late Cretaceous radiolarians (436-41-1, 26-31 cm). 145.5578 145.5578 39.9327 39.9327 145.5578 39.9327 1977-10-01T00:00:00 1977-10-01T00:00:00 -5240.0 -5240.0 not specified DSDP Deep Sea Drilling Project https://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 56-436 39.9327 145.5578 North Pacific/RIDGE -5240.0 1977-10-01T00:00:00 Leg56 Leg56 1977-09-11T00:00:00 1977-09-11 1977-10-07T00:00:00 1977-10-07 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Langseth, Marcus G Langseth, Marcus G von Huene, Roland von Huene, Roland Okada, H Okada, H Nasu, Noriyuki Nasu, Noriyuki doi:10.2973/dsdp.proc.5657.1980 This leg comprised 24 days in the shipyard, 1 day in port calls, 36 days cruising and 19 days on site.
