Description:1:12000 mapping within the pre-Silurian sequence of the Granville-Hancock area, central Vermont, has demonstrated the tectonic nature of contacts between the various units. Taconian pre-peak metamorphic faults (Tn-i) juxtapose discreet lithologies representative of the Pinney Hollow, Mt. Abraham, Hazens Notch, and Ottaquechee formations. Tn-i faults are believed to have large westward displacements which bring together thrust-bound lithologies from differing depositional environments. Kinematic evidence for this displacement is absent due to the obliteration of thrust related fabric by subsequent peak-phase metamorphism. Student paper presented in the Vermont Geological Society quarterly newsletter - Green Mountain Geologist, Spring 1987. Volume 14, Number 1, page 40 of 84 in PDF.
