Regional Geology
This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Paleoproterozoic 1600 - 2500 Ma ID: 2855565 | Felsic and hornblendic gneisses, either separate or interlayered Age: Proterozoic (1600 - 2500 Ma) Description: Includes metabasalt, metatuff, and interbedded metagraywacke; locally contains interlayered biotite gneiss. Derived principally from volcanic rocks Lithology: Major:{gneiss}, Minor:{metabasalt,metagraywacke} Reference: Horton, J.D., C.A. San Juan, and D.B. Stoeser.

Paleoproterozoic 1600 - 2500 Ma ID: 2209151 | Granitic gneiss Age: Proterozoic (1600 - 2500 Ma) Description: Light- to medium-gray, fine- to medium-grained, weakly to strongly foliated monzogranite, granodiorite, and trondhjemite. Composed mostly of quartz, plagioclase, and microcline, with lesser amounts of biotite, ±hornblende, and ±muscovite. Locally contains metasedimentary and amphibolitic inclusions indicating igneous origin, although protolith of some granitic gneiss is uncertain (Braddock, 1969). Age inferred by Sheridan and others (1972) to be same as Boulder Creek Granodiorite (XgdB) and may, in part, be equivalent to foliated facies of Boulder Creek Granodiorite. However, most mapped granitic gneiss probably older than Boulder Creek Granodiorite. Two preliminary U-Pb zircon ages from foliated granodiorite on Mount Morrison in the Morrison 7.5-minute quadrangle are 1,772±10 Ma and 1,771±11 Ma, and a foliated monzogranite from near Deer Creek in the southern Harris Park 7.5-minute quadrangle is 1,766±9 Ma (W.R. Premo, unpub. data, 2007) Reference: Kellogg, K.S., Shroba, R.R., Bryant, Bruce, and Premo, W.R. Geologic Map of the Denver West 30' x 60' Quadrangle, North- Central Colorado.
