Diabase dikes of widespread occurrence intrude only middle Proterozoic rocks in the New Jersey Highlands. These dikes are enriched in TiO2, P2O5, Zr, and light rare earth elements, and have compositions that range from tholeiitic to alkalic.

Dike descriptions, field relations, petrography, geochemistry, petrogenesis, and tectonic setting are discussed. Late Proterozoic diabase dikes of the New Jersey Highlands: a remnant of Iapetan rifting in the north-central Appalachians.

Mafic dikes of late Proterozoic age which cut Grenvillian crust in the northeastern Adirondack Mountains are mostly mildly alkaline basalts except for a few tholeiitic examples. All dikes are high in Ti, P, K, Zr, Y, and LREE, and plot in within-plate fields on tectonic discriminant diagrams.

The Highlands is mainly underlain by highly metamorphosed igneous and sedimentary rocks of Middle Proterozoic age ( billion to about million years old). There are also small areas of Late Proterozoic age metasedimentary rocks and diabase dikes.

Many of the elongate northeast trending valleys within the Highlands are underlain with sedimen. environmental geology of warren county, new jersey bedrock fracture map open-file map ofm 15b plate 1 of 2 new jersey location map row new jersey geological survey bedding 63 —n dip 19 ze- o- 49 6e- 69 79 89 19 39 6e- 69 ze- 29 49 se— 59 69 89 99 b is ne-z19 zn-z;g zze-zpg 59 Ratcliffe, N.M.,High TiO 2 metadiabase dikes of the Hudson Highlands, New York and New Jersey--Possible Late Proterozoic rift rocks in the New York recess: American Journal of Science, v.
