Published: 01 February 1979
Geology (1979) 7 (2): 79-82.
...Joel W. Block; Richard C. Clement; Laurence R. Lew; Jelle de Boer Abstract Since precolonial times, low-magnitude seismic activity has been noted in southeastern Connecticut. South of Colchester, drill holes made in 1970 for roadcut blasting soon developed offsets that provide evidence for recently...

DOI: 10.1130/SPE245-p209
... Revised correlations of critical units in south-eastern Connecticut contradict earlier stratigraphic correlations that led to the interpretation of major recumbent fold napping in the Avalon terrane. The revisions are required in part by the discrimination between lithodemic...

...RICHARD GOLDSMITH; ISIDORE ZIETZ; H. R. DIXON Abstract Radioactivity patterns in southeastern Connecticut, adjacent Rhode Island, and New York closely reflect bedrock units. This relationship is not greatly affected by surficial deposits of Pleistocene age because most deposits are locally derived...

... A section comparable in general aspect to that presented by Bell (1971) for northeastern Massachusetts is present in the New London area, southeastern Connecticut (Fig. 1). Disregarding a fossiliferous sequence, which is possibly in a different structural block, Bell described a 12,800-m-thick...

... terrane of southeastern Connecticut. It also precludes the lithostratigraphic correlation of these orthogneisses with paragneisses. Given this geochemical and geologic evidence, we believe that previously advanced stratigraphic arguments that major recumbent folds relate gneiss bodies now interpreted...

... it. My pleasure is enhanced by knowing Prof. Rodgers personally, albeit rather peripherally. We first met shortly after I began regional mapping in southeastern Connecticut for the U.S. Geological Survey in 1956, and our paths crossed frequently at meetings and NEIGC field trips during the ensuing decade...

... in the south ( Muñoz and Stern, 1989 ). A number of these Pliocene to Pleistocene centers have experienced caldera collapse, including the Copahue-Caviahue volcanic complex, Pino Hachado, and Palao Mahuida. In the early Pleistocene, volcanic centers on the southeastern margin of the uplift erupted alkali...

The belt of transition, however, moved southeast in younger rocks, so that in the middle Paleozoic rocks it lies between the Green, Sutton, and Notre Dame Mountains and the Connecticut and St. Johns Rivers.

... In southwestern Connecticut and southeastern New York, a sequence of Precambrian rocks is unconformably overlain by a Cambrian-Ordovician quartzite-carbonate sequence. This, in turn, is unconformably overlain by a dark-gray fissile sillimanite schist that locally has calcite marble and calcite...
