... A of the Tidwell Member of the Morrison Formation. U/Pb ages and petrography suggest that the Wanakah Formation was sourced, in large part, from the McClure Mountain syenite on the southwestern flank of the Ancestral Front Range. This abrupt change in provenance occurred due to stream capture and drainage...

... in the Middle Proterozoic (1,485 to 1,440 Ma, 1,370 to 1,360 Ma, and about 1,060 Ma). We also report here a zircon age determination (536 ± 4 Ma) for syenite of the Cambrian McClure Mountain alkaline-mafic complex. The granitic gneiss was clearly formed before 1,700 Ma. Its protolith was probably pelitic...
