| Location and accuracy | The Barron prospect is at an elevation of approximately 900 feet on the southwest side of Lone Mountain, 2 miles north of Bear Creek and 1.2 miles west of Stephens Passage. It is in the NE1/4SE1/4 section 19, T. 41 S., R. 65 E. of the Copper River Meridian. The location is accurate within 1/4 mile. |
Geologic descriptionThe Barron prospect consists of a 10-foot thick magnetite- and pyrrhotite-bearing skarn in marble. The skarn can be traced 2000 feet to the northwest and a short distance to the southeast. A large claim block covered this area in 1984 (Wells and others, 1986). No other information is available. The rocks in the area are mainly Ordovician and Devonian to Triassic clastic strata, mafic-intermediate volcanic rocks, and subordinate limestone. The bedded rocks are intruded and locally metamorphosed by Cretaceous granodiorite (Gehrels and Berg, 1994). | |
