This rock is predominantly composed of quartz, alkali feldspar, and plagioclase. The alkali feldspar grains are large and take up a decent amount of the slide. The perthite is mainly one grain that is large and is about 11mm. The plagioclase has
polysynthetic twinning.The muscovite is pleochroic under PPL and has clinopyroxene embayed in the core. Clinopyroxene is present because the melt reacted with the clinopyroxene and create muscovite. Leucite is also present in a minimal quantity. The leucite is embayed in the alkali feldspar. This happened when the alkali feldspar started to crystalize. The silica content was too great and the leucite reacted with the melt to form alkali feldspar. Due to the composition the rock would just be classified as a granite.

Composition includes: biotite, muscovite, chlorite, feldspars, oxides, and quartz. Feldspar poikiloblasts with inclusions of quartz and oxides are prominent throughout much of the sample. Most poikiloblasts occurred synkinematic to the 1st deformation event (D1) and rotation occurred. D1 had a direct effect on the foliation (S1) of minerals that already crystallized. D2 led to crystallization of quartz which is seen in quartz ribbons and pressure fringes throughout the sample.
