A PROVENANCE ANALYSIS OF PASSAIC FORMATION FANGLOMERATE FACIES ADJACENT TO THE RAMAPO FAULT, NEWARK BASIN
Detailed stratigraphic and sedimentological data were collected along a semi-continuous N-S exposure of fanglomerate-sandstone lithofacies north of Milford, New Jersey on Riegelsville/Milford Road along the Delaware River. More than 250 meters of stratigraphic section were measured in shallowly northward dipping strata along a transect that exhibited a general coarsening of conglomerate units north toward the fault. Lithologic variation of component clasts within the conglomerates were estimated and recorded as percentages. Seven clast types have been consistently observed: white/grey quartz/quartzite, oxidized quartz, carbonates, arkosic sandstones, clasts containing abundant quartz veins, and samples containing iron bands. Precambrian metamorphic clasts are uncommon in the measured section. These samples are compared to potential Paleozoic parent materials through hand sample and thin section analysis along with element analysis via SEM-EDS. Analysis of other exposures of the border conglomerates will provide a lateral view of the provenance variability and depositional variability.
