The Mt. Dartmouth 7.5’ Quadrangle, west of the Presidential Range, contains the southeastern portion of the Jefferson Dome, the largest of the Oliverian Domes. As part of a USGS NHGS EdMap StateMap project, the purpose of this study was to remap this part of the Jefferson Dome and perform a structural and mineralogical analysis of its rock units to develop a better understanding of the tectonic history of the Northeast. Structural analyses show dextral shear zones and folded foliation which suggest at least three phases of deformation post-doming. Literature claims shear zones exist throughout the Northeast, and this analysis discovered shear zones through the Jefferson Dome.
