Clay Mineral Sedimentation in the Ocean SpringerLink

This underscores the interest and energy that he deployed throughout his scientific life in order to better understand clay mineral sedimentation in the ocean in the course of the earth’s geological history. His scientific and didactic approaches are expressed in all the publications he was part of or wrote by himself, especially in the

Clay mineralogy and sedimentation in the eastern

1973-8-1  This type of question requires data on relative rates of accumula- tion of the different mineral constituents and therefore depends upon absolute dating of the cores. Insufficient stratigraphic data exist at present to achieve this level of information. Clay mineralogy and sedimentation in the eastern Indian Ocean 731,,,/ =.(, "" -2 19 !,I !

Clay mineralogy and sedimentation in the western

1976-10-1  The clay mineral distributions in the western Indian Ocean are influenced not only by the continental climate and geology but also by the complex physiography of the ocean, submarine volcanism, and several modes of sediment trans- port; hence, the near-perfect latitudinal distri- butions of clay minerals shown by RATEEV, GORBUNOVA, LISITZIN and

Clay mineralogy and sedimentation in the eastern

The distributions of clay minerals in the surface sediments based on about 100 new samples from the eastern Indian Ocean reveal several distinctive sediment sources which differ from those reported previously by other workers. We observe the following: (1) large zones around the periphery of the study area are characterized by abundant smectite.

Clay mineralogy and sedimentation in the western

The clay mineralogy of 235 surface sediment samples from the western Indian Ocean reveals many sedimentary sources and processes: (1) some areas, mainly in the central Indian Ocean, where very little sediment transport is involved, have smectite-rich clays derived from the alteration of in situ submarine basalts. (2) In many other areas, the mineralogy is significantly influenced by several

Clay minerals in recent sediments of the World Ocean

2011-1-19  Problem of the distribution of clay minerals in water areas of the World Ocean and their relation to different (humid, arid, and volcanosedimentary) types of lithogenesis is considered. It is shown that layer silicates can be used as index minerals for distinguishing types of lithogenesis under conditions of marine sedimentation. Humid marine lithogenesis is represented by sediments of the

Mineralogy and Sedimentation of Recent Deep-Sea

From the patterns of mineral distribution, the following conclusions appear warranted: Most Recent Atlantic Ocean deep-sea clay is detritus from the continents. The formation of minerals in situ on the ocean bottom is relatively unimportant in the Atlantic but may be significant in parts of the southwestern Indian Ocean.

Clay Mineral Analysis of Sediments in the Changjiang

Clay mineral analysis was conducted on the fine-grained sediments of a 20-meter core of Late Quaternary deposit in the south-central portion of the modern Changjiang delta plain to understand and characterize paleoenvironmental depositional conditions. Four clay mineral suites (Zones I to IV) were recognized in the core. The lowest level (Zone I, Late Pleistocene) of kaolinite (48%) and illite

In this study, the grain-size and clay-mineral compositions of 73 surface sediment samples collected in a variety of environmental settings in the White Sea are presented to characterize recent sedimentation processes, reconstruct transport pathways, and identify potential source areas of the terrigenous components. Areas >100 m deep are invariably characterized by silty clay, whereas areas

Clay mineral continental amplifier for marine carbon

The majority of carbon sequestration at the Earth’s surface occurs in marine continental margin settings within fine-grained sediments whose mineral properties are a function of continental climatic conditions. We report very high mineral surface area (MSA) values of 300 and 570 m2 g in Late Cretaceous black shales from Ocean Drilling Program site 959 of the Deep Ivorian Basin that vary on

The fundamental motivation for this study was to establish how detrital clay coats and clay minerals (chlorite, illite, kaolinite, and smectite) are distributed in the near-surface (one meter cores; n = 23) of a modern estuarine setting (Ravenglass Estuary, UK; Fig. 1), on a scale similar to many oil and gas fields.This study provides the first integrated near-surface study, which compares the

Clay Minerals as Climate Change Indicators—A Case

The clay mineralogy of the Late Pliocene-Early Pleistocene Pinjor Formation of the type area, northwestern Himalaya, India has been investigated to understand the paleoclimatic conditions and paleotectonic regime prevailing in the frontal Himalayan terrain during 2.5 Ma to 1.7 Ma. The clay minerals were investigated by X-ray diffraction analysis and scanning electron microscope studies.
