FRACTURES IN THE COLLINS CENTER 7.5' QUADRANGLE, WESTERN NEW YORK STATE: IMPLICATIONS FOR FAULTING
Fractures coincident with short-length topographic lineaments indicate structural control of streams. Long lineaments (> ~1 km) are colinear with fracture sets that have a high fracture frequency; these integrated data may indicate locations of faults. In the eastern and western part of the map area, long N-striking topographic lineaments are coincident with N-striking FIDs. A series of at least four NW-striking FIDs are colinear with long NW-striking topographic lineaments. Soil gas anomalies (Nelson, 2001) confirm the NW-striking shallow faults. NE-striking FIDs are present in the northeastern part of the map area where the lineaments are less developed than the NW-striking and NS-striking lineaments. The NE and NW-striking FIDs/lineaments may indicate shallow Alleghanian thrust ramps and lateral ramps associated with the BIT. Deeper structures may also follow these trends. E-W lineaments and fractures also occur in a few localities. The E-W and N-striking FIDs/lineaments may indicate deeper faults that probably affect the Trenton/Black River section.
