Pennington Traprock Co. Quarry


A trap rock (diabase) quarry located 1.0 km (3,400 feet) SW of Marshall's Corner within Hopewell Township.

The Pennington Quarry is excavated in the eastern end of Pennington Mountain. For at least the last 40 years the Pennington Quarry has been operated by Trap Rock Industries. It is just west of Rt. 31 approximately 1.8 miles north of the center of Pennington Boro (Delaware Avenue) in Hopewell Township, Mercer County, New Jersey.

Pennington Mountain is one of several diabase bodies that intrude the middle of the Passaic Formation. These bodies look like stocks in map view but are interpreted as north dipping, finger-like projections from a continuous sill or sheet down dip. They are among the southwestern most extensions of the Palisades intrusive complex. Pennington Mountain is just south of the Hopewell Fault, a major intrabasin fracture. Splays from the Hopewell fault transect the quarry.

In spite of the extensive fracturing of the diabase in the Pennington Quarry secondary minerals have always been very sparse. In addition there has been almost no collecting in this quarry for a very long time if ever.
