Although a gneiss is commonly feldspar- and quartz-rich, the mineral composition is not an essential factor in its definition. Varieties are distinguished by texture (e.g., augen gneiss), characteristic minerals (e.g., hornblende gneiss), or general composition and/or origins (e.g., granite gneiss.

Gneissic rocks in the Rawhide Mountains include both mafic (dark) and felsic (light) layers. The light-colored layer here contains a faint foliation (layering) that is inclined to the left at an angle that is steeper than layering in the surrounding gneiss. This suggests that the rock is sheared, with shearing parallel to layering in the gneiss that is top-to-the-right.
