Sediments of the Continental Shelves

Geological Society of America Bulletin, 1932
Introduction Many geologists have stated that marine sediments vary from coarse to fine directly as the distance from shore and the depth of water increase. Such gradation seems so reasonable in view of our knowledge of waves and currents that what is practically a geologic axiom has come into existence.

Nature of Continental Shelves: DISCUSSION

AAPG Bulletin, 1951
In connection with a discussion of petroleum reserves attributed to shelf areas on the basis of the calculated volume of sediments, concludes that continental shelves are the seaward extension of land masses and that oil possibilities in the downwarped continental margins are related to favorable structure and stratigraphy of the adjacent land area.

Glaciation of the continental shelves (part II)

Polar Geography and Geology, 1984
Over the past two decades, in no small part due to the author's efforts, considerable evidence has accumulated to indicate that a significant proportion of the total mass of the Pleistocene ice sheets lay on the continental shelves rather than on the continents per se.

Holocene sedimentary systems on continental shelves

Marine Geology, 2014
The present knowledge of Holocene continental shelf deposits in relation to the processes for their formation, from the prospective of marine sediment dynamics, is examined. Over the last 50 years, various innovative techniques have been developed to measure and calculate currents, waves and suspended sediment concentrations.

Ocean Coasts and Continental Shelves

2007
Suess (1900) provided the first scientific treatment of the South American coast from a tectonic perspective when he distinguished between the Atlantic and Pacific structural styles on opposite sides of the continent. Inman and Nordstrom (1971) later complemented this approach by relating these styles to the concepts of plate tectonics that had emerged

Glacial Troughs of the Continental Shelves

The Journal of Geology, 1931
Submarine valleys may be classified into three groups. One group resembles youthful river valleys, another fault grabens, and a third glacial troughs. There are many reasons for believing that the valleys of this last group have been shaped by glacial excavation. They are found exclusively off glaciated coasts. They contain the deep-rimmed depressions,

Characteristics of Continental Shelves and Slopes

AAPG Bulletin, 1965
One of the most important and interesting geological questions awaiting solution is that of the origin of continental shelves and slopes. Just as for other geological features, more than a single origin is involved for different areas or for different times.

The effect of continental shelves on tides

Deep Sea Research Part A. Oceanographic Research Papers, 1981
Abstract Coastal tides are influenced by several factors and one of the most important of these is the character of the adjacent continental shelf. A continental margin theory is derived and used to discuss several different aspects of the effect “smooth” continental shelves have on tides. The main results are as follows.

Major Synchronous Events in Continental Shelves

Tectonophysics, 1976
Abstract Kent, P.E., 1976. Major synchronous events in continental shelves. In: M.H.P. Bott (editor), Sedimentary Basins of Continental Margins and Cratons. Tectonophysics, 36 (1–3): 87–91. The modern Atlantic-type continental shelves mostly originated around the Permian, and showed a history of dominantly fault-controlled subsidence through the ...

Variations in History of Continental Shelves

AAPG Bulletin, 1950
Some students of continental shelves consider the shore line which bounds the shelf toward the land as a hinge line, the landward side uplifted, and the shelf area downwarped with extensive sedimentation. The writer presents another theory, that the shore line is not the locus of any movement, but that the continental shelf and the adjacent land differ
