Perhaps like porphyry, it was ignored by the successive dynasties of Egypt and only heavily mined during Ptolemaic or Roman times. This is evidenced ...
Tonalite–trondhjemite–granodiorite (TTG) rocks are intrusive rocks with typical granitic composition (quartz and feldspar) but containing only a small portion of potassium feldspar. Tonalite , trondhjemite , and granodiorite often occur together in geological records , indicating similar petrogenetic processes. [ 1 ]
Kuna Crest Granodiorite (also called Granodiorite of Glen Aulin), [1] is found, in Yosemite National Park, United States. The granodiorite forms part of the Tuolumne Intrusive Suite (aka Tuolumne Batholith), one of the four major intrusive suites within the Sierra Nevada.

Sentinel Granodiorite is a light-gray and medium-grained biotite-hornblende granodiorite. The color index is normally about 15, and ranges from 10 to 25. The hornblende is tabular, of crystals which are usually 4 - 6 millimeters long, and helps to define a weak to moderately strong magmatic foliation and lineation .
