Mesoproterozoic
1000 - 1600 Ma



ID: 2208152
Granodiorite of Mount Evans batholith

Age: Mesoproterozoic (1000 - 1600 Ma)

Description: Gray, massive to strongly foliated, coarse-grained, mostly porphyritic biotite-hornblende granodiorite, which ranges in composition from monzogranite to tonalite (Aleinikoff and others, 1993a). Locally contains as much as 5 percent of an aplite-pegmatite phase consisting of dikes and irregular-shaped bodies of massive to weakly foliated aplite and magnetite-bearing pegmatite. Formerly believed to be part of the Early Proterozoic Routt Plutonic Suite of Tweto (1987), due to petrographic and textural similarities to rocks of that suite and limited Rb-Sr data (for example, Bryant and Hedge, 1978). However, U-Pb zircon date is 1,442±2 Ma (Aleinikoff and others, 1993a), confirming emplacement with Middle Proterozoic Berthoud Plutonic Suite of Tweto (1987)

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
