Analysis of the variation in carbonate Contint versus time in sediments from the basins of the California Continental Borderland reveals that the high carbonate sediments correlate with relatively warm water period. This is verified by oxygen isotopic data and micropaleontologic data. In warm times turbidity current contribution is small and the dilution effect of terrigenous sediments is minimal. Conversely, during periods when sediments have low carbonate content the terrigenous sediment rates are high turbidities are common and the influence of local clay sources increases. Examination of the regional patterns of sedimentation shows that the upwelling intensity increased in the area at least two-fold and terrigenous sediment input also increased as much as five-fold during the most recent cold period. It is suggested that this reflects a movement of climatic belts toward the Equator and a concommittant increase in runnoff and upweeling rate. (Author).

Download Mineralogy of Hemipelagic Basin Sediments, California Continental Borderland Book in PDF, ePub and Kindle
Minerals in Holocene and late Pleistocene basin sediments of the northern California Continental Borderland are derived from local sources, and in minor amounts from wind- and current-borne sediment. Source, sea level fluctuations, differential settling, and sedimentation by floods control the distribution of the mineralogy. River-sediment mineralogy can be divided into northern sedimentary, central igneous-metamorphic, and southern batholithic suites. Analysis of cores reveal mineralogic variations that are largely contolled by sea-level fluctuations. Numerous well-sorted gray silt layers in Santa Barbara Basin appear to be flood-deposits that formed after unusually heavy storms, such as occurred in 1969. (Author).

Download Late Pleistocene Sedimentary History of Continental Borderland Basins Off Baja California and Southern California: Changes in Terrigenous and Biogenic Sedimentation Rates Book in PDF, ePub and Kindle
Analysis of sediment cores yields a record of sedimentary history for the past 35,000 years and includes a complete cold to warm climate cycle. Sedimentation rates have been calculated using open ocean records as a dating tool plus some radiocarbon dates and data from micropaleontologic and oxygen isotopic data. These show that sedimentation rates have varied several fold and that the main effect is exerted by the terrigenous continental input. Pelagic biogenic input has also varied in parallel with the terrigenous contribution but at much lower rates. Organic carbon content parallels carbonate and shows a slight offset in terms of percent of total sediment due to terrigenous dilution and also to rapidity of burial. Slower rates over the past 6000 years have produced lower buried carbon values. Variations appear to be synchronous with the deep ocean record. (Author).

Download Economic and Palaeoceanographic Significance of Contourite Deposits Book in PDF, ePub and Kindle
There has lately been a growth in the number and level of studies of contourite deposits. Most recent studies of contourites have two major lines of interest. One, propelled by the oil industry's continuous move into increasingly deep waters, concerns their economic significance. The other involves the stratigraphic/ palaeoceanographic record of ocean circulation changes imprinted on contourite deposits that can be a key to understanding better the climate-ocean connection. The application of many different theoretical, experimental and empirical resources provided by geophysics, sedimentology, geochemistry, petrology, scale modeling and field geology are used in the 16 papers of this volume, proposing answers to those two main aspects. The papers are subdivided into two major categories (economic interest and stratigraphic/palaeoceanographic significance), with case studies ranging from well-documented drifts to new examples of modern and fossil series, involving a large diversity of geographic and physiographic scenarios worldwide
