Wellman Hall is one of the main building, completed on 1902, on the west entrance of the UC Berkeley campus. The main circular tower entrance of the building has a large archway with light, fine grained granodiorite hanging overhead, the wall and the trim of the windows are also covered in this light colored granodiorite, the rocks covering the wall and windows has mostly quartz, potassium feldspar, mica, and biotite. The small pieces biotite creates a “flaky” and “sparky” effect when walking by the building at a close proximity. This granodiorite is an intrusive igneous rock, that comes from the Sierra Nevada Mountains, the rocks are not smooth or polished but rather have a hand-chiseled and rough look, from a distance the outside of the building
