IRON ORE DEPOSITS OF THE NEW JERSEY HIGHLANDS
History Iron mining activity in the New Jersey Highlands pro bably began about 1710 (Sims, 1958). Maximum pro duction was attained in the early 1880's when New Jersey ranked second only to Michigan in iron ore pro duction. For several years before and during 1880 New Jersey was the leading iron ore producing state. Geologic Setting

The Mineville district produced two distinct varieties of iron ore (Birkinbine 1890): magnetite-apatite and magnetite-silicate ore. The magnetite-apatite ore was produced from what was called the "Old Bed" and the magnetite-silicate ore came from the "New Bed". These names were applied to the ore mined from different mining works.
