The study area extends 27 km in an east-west direction and 8 km north-south and is located along the trace of a tunnel currently being constructed approximately 90 m below grade. Structural data are presently being collected from surface exposures along the tunnel trace and from within the 5 m diameter tunnel bore. These structural data will be compared with lineament data in the future. Reported here are the results of a comparison between the locations of lineaments and the position of major faults mapped on the Bedrock Geologic Map of Massachusetts (1:250,000). Lineaments were first mapped on acetate overlays in two independent trials and compared to determine which lineaments could be reproduced at the same geographic location. Reproducibility results indicate that 21 to 33% of the lineaments can be reproduced at the same spatial position and are comparable to results obtained from other studies. The length of reproducible lineaments proximal to and approximately parallel with mapped faults was compared with the total length of faults (137 km) within the study area. Results show that a small percentage of the faults are coincident with reproducible lineaments. Three percent of the lengths are mapped by reproducible lineaments observed on the SLAR imagery, 7% by the 1:80,000 scale photographs, and 5% by the 1:58,000 color infrared photography. This indicates that 97%, 93%, and 95% of the reproducible lineaments, respectively, are related to other geologic features in the bedrock or nothing at all.

Lineaments were drawn by three observers during two independent trials to produce 18 sets of lineaments (n = 9137) covering approximately 1,000 km (super 2) centered over the tunnel. All lineaments for each platform were compared. Three or more overlapping lineaments (azimuths within 5 degrees and within 1 mm at the scale of the imagery) define a single coincident lineament. This analysis generated three sets of coincident lineaments (n = 794), of these 37 cross the tunnel. Buffers were placed around the coincident lineaments at a distance of 1 mm from the center of the lineament at the scale of the platform (e.g. 250 m for the SLAR image). The Mann-Whitney U test was used to determine if the median flow from all tunnel structures which underlie the lineament buffer zones is significantly greater than that of all structures outside of the buffer zones. Results indicate that median flow (11,000 l/day) from structures located within the buffer zones of the BW are significantly greater at the 90% confidence level than the median flow (5,500 l/day) of structures located outside the buffer zones. No significant differences in flow were found for the other two platforms. Subsurface structures that parallel coincident lineaments (all platforms) and occur within the buffer zones have higher median flow (10,500 l/day) than those structures outside the buffer zones (6,600 l/day). However, this difference is significant at the 70% confidence level. These results suggest that, in some instances, a thorough lineament analysis can predict water-bearing subsurface structures in poorly exposed, glaciated, metamorphic terrain that has a high degree of suburban development.
