چکیده انگلیسی
Geochronologic data provide a temporal constraint on late-stage hydrothermal activity and a metallogenic event in New Jersey at â¼990 to 940 Ma that mineralized pegmatites with subeconomic to economic deposits of magnetite ± U ± Th ± rare earth element (REE) and formed metasomatic calcic skarn bodies in marble and reactive carbonate rocks. Mineralization associated with this event overlaps the timing of pegmatite emplacement, suggesting a petrogenetic relationship. Coeval metallogeny at 975 to 950 Ma in the New York Hudson Highlands and 980 to 937 Ma in the Canadian Grenville Province implies that this event was widespread following the Ottawan phase of the Grenville Orogeny.
