The Intrusive Suite of Sonora Pass is ~92-89 Ma, and is the northernmost of four large Late Cretaceous zoned intrusive suites in the central Sierra Nevada batholith.[1] What rocks compose the Intrusive Suite of Sonora PassOn a large scale, it is composed of Kinney Lakes granodiorite and the younger Topaz Lake granodiorite.[2] On a finer scale, the Intrusive Suite of Sonora Pass is made of light-gray, coarse-grained biotite granodiorite, plus granite with roughly equant, well-formed potassium feldspar phenocrysts composing about 2–10% of the rock. Quartz usually occurs in clots of {{convert|0.5|cm|in}}. The mafic mineral content is about 10%.[3] References1. ^{{cite web | url=https://gsa.confex.com/gsa/2014RM/webprogram/Paper238414.html | title=Structure and Construction of the Cretaceous Sonora Pass Intrusive Suite, a large zoned intrusion of the Sierra Nevada Batholith, California | publisher=gsa.confex.com | date=May 2014 | accessdate=8 January 2019 | author=Leopold, Monika}} 2. ^{{Cite web |url=https://scholarworks.sjsu.edu/cgi/viewcontent.cgi?article=8310&context=etd_theses |title=Structure, Construction, and Emplacement of the Late Cretaceous Sonora Pass Intrusive Suite: Central Sierra Nevada Batholith, California |last=Leopold |first=Monika B. |date=2016}} 3. ^{{cite web | url=http://npshistory.com/publications/yose/nrr-2012-560.pdf | title=Yosemite National Park: Geologic resources inventory report.
