Sediments And Shallow Stratigraphy Of A Portion Of The Continental Shelf Of Southeastern Virginia, Carl H. Hobbs Iii Aug 1997

Sediments And Shallow Stratigraphy Of A Portion Of The Continental Shelf Of Southeastern Virginia, Carl H. Hobbs Iii

Reports

A network of high-resolution, seismic-reflection profiles and grab samples of the surficial sediments of the inner continental shelf of southeastern Virginia demonstrate that the Quaternary geology of the region is more complex than indicated by earlier studies. The spatial variability of the surficial sediments depicts active processes, such as outflow from Chesapeake Bay, as well as the underlying geology in outcrops of finer grained sediments near False Cape.

The complexity of the Quaternary geology results from large and small scale fluctuations in sea level. Individual, relatively large-scale, seismostratigraphic units are separated by erosional surfaces formed during the major changes in ...


Pliocene And Pleistocene Depositional Environments On The York-James Peninsula, Virginia; A Field Guidebook, Gerald H. Johnson, Carl H. Hobbs Iii Jun 1990

Pliocene And Pleistocene Depositional Environments On The York-James Peninsula, Virginia; A Field Guidebook, Gerald H. Johnson, Carl H. Hobbs Iii

Reports

The late Cenozoic deposits of southeastern Virginia represent a wide variety of depositional environments and record numerous marine transgressions. The formations range in age from Miocene to Holocene. This fieldguide provides an opportunity to visit and sample highly fossilferous marine bay and fluvial-estuarine sediments exposed in river bluffs and borrow pits on the York-James Peninsula.

Assessment Of Economic Heavy Minerals Of The Virginia Inner Continental Shelf, C. R. Berquist, C. Hobbs Jan 1986

Assessment Of Economic Heavy Minerals Of The Virginia Inner Continental Shelf, C. R. Berquist, C. Hobbs

Reports

The Virginia Division of Mineral Resources and the Virginia Institute of Marine Science jointly made three cruises over the Virginia continental shelf in April and July of 1985 to sample known heavy-mineral sites for minerals of potential economic and/or strategic value. In addition to sampling, side-scan sonar and sub-bottom profiling surveys were performed at a site off Smith Island. At the Smith Island site, as many as four acoustic horizons were detected within the upper 6 meters of sediment. The uppermost seismostratigraphic layer consists of fine and very fine sand and contains the higher concentrations of heavy minerals. There ...

Bahamas Bibliography : A List Of Citations For Scientific, Engineering And Historical Articles Pertaining To The Bahama Islands, Carol Fang, W. Harrison Jan 1972

Bahamas Bibliography : A List Of Citations For Scientific, Engineering And Historical Articles Pertaining To The Bahama Islands, Carol Fang, W. Harrison

Reports

Specialized bibliographies are sometimes needed in connection with the research studies being pursued at the Virginia Institute of Marine Science. The Bahamas Bibliography arose out of the needs of marine geologists, biologists and physical oceanographers engaged in studies of beaches, fishes and inlet currents in the Bahama Islands. Although the present bibliography may suffer from completeness, it significantly surpasses in number of citations the only other known bibliography of like kind.


Inner Shelf Sediments Off Chesapeake Bay. I - General Lithology And Composition, Maynard M. Nichols Jan 1972

Inner Shelf Sediments Off Chesapeake Bay. I - General Lithology And Composition, Maynard M. Nichols

Reports

The sedimentary materials and bottom topography of more than 2400 square miles of the inner continental shelf floor north off the Chesapeake Bay entrance have been surveyed for potential mineral resources. Sediments consist of two principal types: (1) fine sand and (2) medium to coarse sand. The fine sand is grey-colored, subrounded, rich in quartz and relatively 11clean 11 and well sorted. The medium-coarse sand is typically iron-stained, rich in shell and poorly sorted. The fine sand covers inner parts of the shelf floor whereas medium to coarse sand covers seaward parts. Additionally, shell-rich medium to coarse sand occurs on ...
