Geologic Units
The geology for the South Pass belt was investigated by Hausel.
This elongate greenstone belt is characterized by Hausel as a synclinorium of metamorphosed volcanic, sedimentary and plutonic rocks that have been regionally metamorphosed to greenschist and amphibolite facies, and locally overprinted by a later retrogressive greenschist facies event. The axis of the belt is paralleled by foliation, shear zones, and lower order fold axes, and has been intruded along its flanks by granite and granodiorite.

Famous quotes containing the word units:
“Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbours household, and, underneath, anothersecret and passionate and intensewhich is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.”
—Willa Cather (18731947)
