【 摘 要 】

In the structure task, the goals for this reporting period were to: (1) complete analyses of field work on the NNW-SSE transect along the west side of Cayuga Lake. We have completed data input and analyses for this goal, and discuss the results. The additional data from the 2002 field season (and additional revised data from the previous season) demonstrate that zones of closely-spaced E-striking fractures bear a close spatial correlation with the E-striking Firtree Anticline. East-striking EarthSat (1997) Landsat lineaments also occur in the same general region as the Firtree Anticline. However, one E-striking lineament occurs where we have no sites with a high E-striking fracture frequency. ENE-striking closely-spaced fractures occur where ENE-striking lineaments occur. From the Seneca lake transect, these fractures intensification domains and lineaments are thought to mark zones of reactivated Trenton/Black River faults. In the advanced seismic analyses task, the goals for this reporting period were to complete analyses of the seismic data. We have completed data the data analyses and find that high porosity zones can be recognized along some of the Trenton/Black River fault zones. These data continue to demonstrate that integration of aeromagnetic and Landsat lineaments, surface structure, soil gas and seismic allows us to extrapolate Trenton-Black River trends away from confirmatory seismic lines.
