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.

Permian - Devonian
252.17 - 419.2 Ma



ID: 3187583
Paleozoic sedimentary rocks

Age: Paleozoic (252.17 - 419.2 Ma)

Lithology: Sedimentary rocks

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]

Early Ordovician - Late Cambrian
470 - 501 Ma



ID: 3301453
Manitou Dolomite, including Upper Cambrian Taylor Pass Member of Myrow and others

Age: Paleozoic (470 - 501 Ma)

Stratigraphic Name: Manitou Dolomite

Description: Gray to light tan, locally mottled, fine- to medium-crystalline, thin to thickly bedded, dolostone and rare beds of dark-gray limestone; locally fossiliferous (crinoids, gastropods, echinoderms, nautiloids, and trilobite fragments). Lower part contains mostly white, but also gray and black chert nodules, lenses, and layers; very sparse white chert in upper part of formation. Contains flat-pebble (limey mudstone clasts) conglomerate (Widmann and others, 2011), just above Upper Cambrian Taylor Pass Member of the Manitou Dolomite of Myrow and others (2003). The Taylor Pass Member has an upper, resistant, purple-tinged dolomite overlying dark-red shale; the member was historically called the “red-cast beds” (Emmons and others, 1886), and was formerly considered the upper part of the shaly Peerless Formation (Behre, 1953; Tweto, 1974a). The Taylor Pass Member pinches out southward beneath the Buffalo Peaks, so the Upper Cambrian beds of the Manitou are mapped only north of the Buffalo Peaks (Widmann and others, 2011; Houck and others, 2012; Tweto, 1974a; Bohannon and Ruleman, 2013). Has disconformable contact with underlying Dotsero Formation. About 65 m thick

Paleoproterozoic
1600 - 2500 Ma



ID: 2855911
Granitic rocks of 1700-m.y. age group

Age: Proterozoic (1600 - 2500 Ma)

Stratigraphic Name: Boulder Creek Granite; Cross Creek Granite; Denny Creek Granodiorite; Kroenke Granodiorite; Browns Pass Quartz Monzonite; Powderhorn Granite; Pitts Meadow Granodiorite; Bakers Bridge Granite; Tenmile Granite

Description: Includes Boulder Creek -M.Y. AGE GROUP (AGE 1650-1730 M.Y.)--Includes Boulder Creek, Cross Creek, Denny Creek, Kroenke, Browns Pass, Powderhorn, Pitts Meadow, Bakers Bridge, and Tenmile Granites, Quartz Monzonites, or Granodiorites; also, unnamed granitic rocks

Lithology: Major:{granite}, Minor:{granodiorite,quartz monzonite}
