ID: 2860427
Proterozoic basement rocks - Felsic phaneritic intrusive rocks

Age: Mesoproterozoic (1000 - 1600 Ma)

Description: This porphyritic rapakivi granite is present only in Clark County where it intrudes Proterozoic gneiss and schist (Xm).

Comments: Original map source: Crafford, A.E.J., 2007, Geologic Map of Nevada: U.S. Geological Survey Data Series 249, 1 CD-ROM, 46 p., 1 plate; Scale 1:250,000.

Mesoproterozoic
1000 - 1600 Ma



ID: 3172761
Gold Butte Granite

Age: Mesoproterozoic (1000 - 1600 Ma)

Stratigraphic Name: Gold Butte Granite

Description: Described by Volborth (1962) as rapakivi granite. Coarse-grained porphyritic to locally equigranular biotite and biotite-hornblende granite. Contains 5 to 50 percent phenocrysts of potassium feldspar 1to 3 cm across; Fryxell and others (1992) mapped phenocryst content as decreasing generally westward. Mafic mineral content about 10 to 20 percent. Preferred alignment of tabular phenocrysts and biotite define faint igneous foliation. Locally gneissic. Age of 1.45 ± 0.25 Ga has been reported by Silver and others (1977; no location information available)
