- Abstract:
-
Cores collected from recent drilling in western Cape Cod, Massachusetts provide insight into the topography and petrology of the underlying bedrock. Cores from 64 drill sites spread over a ~140 km2 study area produced samples of granitoids (31), orthogneisses (20), basalts/diabases (4), amphibolites (3), felsic mylonites (2), and dolomitic rock (2). Granitoid composition ranges from granite to tonalite and quartz diorite, but it is dominated by two-feldspar granites. Hydrothermal alteration is common in nearly all cores as evidenced by the secondary growth of chlorite and epidote. Granitoids resemble rocks of the Dedham and Fall River plutons (Wones and Goldsmith, 1991). Gneisses generally contain the mineral assemblage K-feldspar+plagioclase+quartz±biotite± chlorite±muscovite±sphene±epidote+oxides. Amphibolites contain the assemblage hornblende+plagioclase+quartz+biotite+epidote±chlorite±sphene±K-feldspar±sericite+ oxides. Peak metamorphic grade based on mineral assemblages is estimated at lower amphibolite facies. X-ray powder diffraction of unmetamorphosed dolomitic cores shows presence of layered silicates (clays), plagioclase, and possible magnesite. Contours of the bedrock surface show locally irregular topography suggesting erosion by glacial scour. Lithologic distribution mapping suggests a possible continuation of the New Bedford gneissic terrane that outcrops 25 km to the west. Dolomitic rocks may represent a lithified fault gauge material at the eastern edge of the gneissic zone. Basalts/diabases are interpreted to be post-metamorphic dikes associated with Mesozoic rifting. Note: These data were reprojected from their native projection into North American Datum 1983 (NAD83) / Massachusetts State Plane coordinate system, Mainland Zone (Fipszone 2001) meters by the Massachusetts Office of Coastal Zone Management on June 21, 2006.
- Purpose:
-
The purpose of this data layer is to provide those interested in the composition and character of the bedrock beneath western Cape Cod with the ability to examine the well logs and sample descriptions in a geographic context.
