The Deep Sea Drilling Project: A Decade of Progress
At the present the Glomar Challenger has drilled over 500 holes over the world ocean, involving hundreds of scientists from dozens of countries. This volume is intended as a review of some of theimportant results from the most comprehensive, ambitious and successful earth-bound geologic project ever undertaken. The symposium upon which this volume originated was held April 4, 1979 at the SEPM/AAPG Annual Meeting in Houston. No comprehensive synthesis of all aspects of the DSDP has appeared, and the topic coverage in this volume is biased towards the sediments and fossils, and their significance for certain aspects of earth history – paleogeography, bathymetry, climatology, oceanography, ecology, environments – all in keeping with the audience of sedimentary geologists.

Quantitative studies of the preservation and biogeographic distribution of calcareous nannofossils in Mid-Cretaceous sediments from the Atlantic are combined with observations on the temporal and spatial distribution of major facies patterns to put constraints on speculations about the paleoceanographic evolution of the Atlantic about 110 to 90 m.y.BP. Organic-rich sediments in deep ocean and continental margin settings are indicative of organic carbon influx from terrestrial and marine sources and considerable carbonate dissolution largely caused by carbon dioxide production during catabolic breakdown of organic matter. Preservation of organic carbon in sediments is the result of rapid burial, especially along continental...
