Thus, the basement underlying the Island has been practically inaccessible, sampled only in scattered borings, building excavations, and municipal construction efforts. In the last few years, however, construction of the Queens Tunnel (Stage 2 of City

Rather, internally sheared and migmatized units of the Hartland and Walloomsac formations and associated granitoid rocks clearly predominate. This extended abstract outlines the distinction between the various schist units in four of the more interesting sites and offers

For most of its course, the Bronx River flows in such a strike-valley lowland. However, just at the point where the NW-SE-trending Mosholu fault offsets this marble lowland, the Bronx River leaves the lowland and flows southward across the more-resistant gneisses and schists of the Hartland Formation in the narrow-N-S-trending Snuff Mill gorge.
