A major New Jersey iron mine started about 1722 and ultimately closed 1916 with stepped abandonment during the period 1907 & 1908. Estimated total production to 1916 is 5,000,000 tons of magnetite ore. Workings in 1910 went to a depth of 1,200 feet (SW end) and 1,500 feet (NE end).

This mine incorporated the following earlier workings: Scott mine, Lower Wood mine, Church mines, Wharton mine, Willis mine, Upper Wood mine, De Camp mine, Glendor (Crane) mine. Consolidation started about 1890 and was completed by 1901.

The Hibernia orebody had the longest outcrop length of any massive magnetite deposit in New Jersey, approximately 7000 feet. The southwest end was in the village of Hibernia. From here it stretched northeast to Shaft #12 Located just beyond the end of the surface outcrop.

Mesoproterozoic
1000 - 1600 Ma



ID: 2986227
Amphibolite

Age: Mesoproterozoic (1000 - 1600 Ma)

Description: Gray- to grayish-black, medium-grained amphibolite composed of hornblende and andesine. Some phases contain biotite and (or) clinopyroxene. Ubiquitous and associated with almost all other Middle Proterozoic units. Some amphibolite is clearly metavolcanic in origin, some is metasedimentary, and some appears to be metagabbro.

Comments: Rocks of Uncertain Origin (Middle Proterozoic) Original map source: Dalton, R.F., Herman, G.C., Monteverde, D.H., Pristas, R.S., Sugarman, P.J., and Volkert, R.A., 1999, New Jersey Department of Environmental Protection, Bedrock Geology and Topographic Base Maps of New Jersey: New Jersey Geological Survey CD Series CD 00
