Mount Eve Granite (NJYgm;11)

Mount Eve Granite (Drake and others, 1991a) - Light-pinkish-gray or grayish-tan-weathering, light-gray to pinkish-gray, medium- to coarse-grained granite containing microcline microperthite, quartz, oligoclase, and biotite. Common accessory minerals include hornblende, biotite, magnetite, and allanite. Most of the rock is a syenogranite. Upper intercept U-Pb age of 1,020 +/- 4 Ma (Drake and others, 1991a). Occurs in Pochuck Mountain area along New York boundary.
