Summary
This series contains unpublished maps, cross- sections, and related information archived by the State Geological and Natural History Survey of Connecticut as part of the Survey Library Collection. These materials have not been reviewed for accuracy, consistency, or completeness. For many geographic areas, more current information exists, either in published or unpublished form. For the most part, these materials were developed under research and mapping agreements betweenthe State Geological Survey and individual scientists, academic institutions, or graduate students. Some of these materials have been received by the State Geological Survey as donations. The veracity of the information contained within these documents is the responsibility of the authorship. The State Geological and Natural History Survey of Connecticut, does not promote or endorse this content, nor does the State Survey attest as to its level of accuracy.
These materials have been preserved under a cooperative agreement between the State Geological Survey and the US Geological Survey as part of the National Geological and Geophysical Data Preservation Program (www.datapreservation.usgs.gov).
These materials are offered in the spirit of open government. Reproduction of these manuscripts was conducted to the highest practical degree, within the parameters of the funding mechanism. Original documents are available for inspection by contacting the Connecticut State Geologist. New Haven Harbor Study and Subsurface Geologic Interpretation- John Sanders (1965) Sanders, John E., 1965, Sediment-Filled Deep Valleys Underlying New Haven Harbor, Connecticut, Revealed by Continuous Seismic Profiling Using Sparker and Pneumatic Sources. American Geophysical Union, Forty Sixth Annual Meeting Program, April 19-22, 1965, Oceanography Abstracts, Marine Geophysics.
The Sanders New Haven Map Series details the work described in the 1965 AGU abstract, and includes unpublished boring logs, interpretive map overlays for depth to rock, thickness of Quaternary sand, organic silt, geophysical profile track lines, and summary figures. Sanders also provides early documentation of 3 deep V-shaped bedrock valleys within the harbor, interpreted to be extensions of Triassic faults, the largest of which near West Haven is interpreted to have several km of left-lateral strike slip movement.
Correspondence between Sanders and Connecticut Geological and Natural History Survey Director Joe Peoples (1971) provides detail on the surveys and suggests publication of the work as a State Survey Report of Investigations. A reply by Sid Quarrier of the State Geological and Natural History Survey supports consideration of the Study as a Report of Investigations, and describes both the purpose of the publication and a possible outline of content.
The Sanders unpublished map series and accompanying data is cited by Rodgers (1985) as source material for the Statewide Bedrock Geological Map of Connecticut for 1:24,000 scale map compilations for the New Haven quadrangle. As such, this work may be the basis for the extension of the Eastern Border Fault through New Haven Harbor into Long Island Sound through West Haven.
Original materials are not available for loan; content accessable online through the Connecticut Geological Survey, Department of Energy and Environmental Protection.
