A recently discovered gabbroic-granitic complex closely resembles other huge stratiform or lopolithic bodies. The complex was emplaced within and below a thick volcanic pile that formed slightly before the gabbroic phase, Folding, faulting, and locally intense shearing hav e affected the complex and its country rock. Younger stocklike masses of hornblende and biotite granite cut indiscriminately the igneous complex and adjacent rocks and appear emplaced by ring-fracture sloping.
