Furnace Bed (Pikes Peak mine)
New Jersey Highlands, United States
OtherFe
- Type
- Silicate-poor magnetite hosted in marbles
Small magnetite deposit in Mesoproterozoic marbles of the New Jersey Highlands, metamorphosed in Grenvillian times. The authors see Fe oxides and hydroxides brought by a back-arc submarine hydrothermal system (1.3 to 1.25 Ga), the same as for the zinc at Franklin and Sterling Hill.
