magnetite ore in new york

Magnetite ore formed during regional metamorphism,

This investigation is a geological and geochemical study of several magnetite deposits in the Ausable magnetite district of New York. Geologic maps were prepared of part of the district and of these deposits, and laboratory investigations were carried out on the host rock gneiss and its constituent minerals.The Lyon Mountain granite gneiss appears to have been the source rock from which the
