Mesoproterozoic
1000 - 1600 Ma



ID: 2855986
Granitic rocks of 1400-m.y. age group

Age: Mesoproterozoic (1000 - 1600 Ma)

Stratigraphic Name: Silver Plume Granite; Sherman Granite; Cripple Creek Granite; St. Kevin Granite; Vernal Mesa Granite; Curecanti Granite; Eolus Granite; Trimble Granite

Description: Includes Silver Plume, Sherman, Cripple Creek, St. Kevin, Vernal Mesa, Curecanti, Eolus, and Trimble Granites or Quartz Monzonites; also, San Isabel Granite of Boyer (1962) and unnamed granitic rocks

Comments: Original map source: Green, G.N., 1992, The Digital Geologic Map of Colorado in ARC/INFO Format: U.S. Geological Survey Open-File Report 92-0507, 9 p., scale 1:500,000.

Paleoproterozoic
1600 - 2500 Ma



ID: 2442070
Gneiss

Age: Proterozoic (1600 - 2500 Ma)

Description: Composed primarily of gray medium-grained foliated gneiss, consisting mainly of quartz, plagioclase, and biotite, and foliated micaceous schist. Includes large areas of migmatite and migmatitic gneiss near major bodies of Pikes Peak Granite, Silver Plume Quartz Monzonite, and Boulder Creek Granodiorite, as well as garnet, sillimanite, and cordierite-bearing gneisses.

Paleoproterozoic
1600 - 2500 Ma



ID: 3186950
Paleoproterozoic crystalline metamorphic rocks

Age: Proterozoic (1600 - 2500 Ma)

Lithology: Orthogneiss/paragneiss

Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154]

Paleoproterozoic
1600 - 2500 Ma



ID: 2209305
Biotite gneiss

Age: Proterozoic (1600 - 2500 Ma)

Description: Gray, medium-grained, equigranular, well-foliated gneiss typically containing approximately 25–50 percent quartz, 20–30 percent plagioclase (approximately An30), 0–30 percent microcline, 10–15 percent biotite, 0–15 percent muscovite, 0–10 percent sillimanite, 0–5 percent hornblende, 1–2 percent opaque minerals, and a trace zircon. Most outcrops contain 5–20 percent granitic layers (leucosomes). Sillimanite, where abundant, occurs in fibrous, elongate, light-colored aggregates or clots as wide as about 1 cm. Migmatitic biotite gneiss in Clear Creek gave preliminary U-Pb zircon date on nonmelt phase of 1,773±18 Ma; near Pine, just south of map area, similar rock gave U-Pb zircon date of 1,780±9 Ma (W.R. Premo, unpub. data, 2005)
