BEDROCK GEOLOGIC MAPPING AND STRUCTURAL ANALYSIS OF THE WESTERN HALF OF THE PETERSHAM QUADRANGLE, CENTRAL MASSACHUSETTS: FURTHER TESTS OF THE MODEL FOR MIDDLE TO LATE PALEOZOIC DUCTILE TRANSPRESSION, VERTICAL EXTRUSION, AND LATERAL ESCAPE IN THE NORTHERN APPALACHIANS

BEDROCK GEOLOGIC MAPPING AND STRUCTURAL ANALYSIS OF THE WESTERN HALF OF THE PETERSHAM QUADRANGLE, CENTRAL MASSACHUSETTS: FURTHER TESTS OF THE MODEL FOR MIDDLE TO LATE PALEOZOIC DUCTILE TRANSPRESSION, VERTICAL EXTRUSION, AND LATERAL ESCAPE IN THE NORTHERN APPALACHIANS

Bedrock mapping, structural analysis, and geochronology reveal the distribution of lithologies and timing of metamorphism and deformation in the western half of the Petersham 7.5’ quadrangle, western Massachusetts. Underlying lithologies are: (from west to east) the Ordovician Monson granitic orthog...
