The Great Notch Corp. Quarry is located approximately 2000 feet northwest of the Houdaille quarry in Little Falls Township, New Jersey. This quarry ceased operation at the beginning of the 1970’s. As I recall closure was due to a family dispute among the owners. Later the site was occupied by Franklin Contracting, a construction firm, as an equipment storage yard.

This quarry was certainly one of the fainter stars among the constellation of specimen producing quarries in the Orange Mountain (First Watchung) basalt. Prior to 1970 it apparently did produce a small amount of material typical of the region. The Great Notch Quarry is notable only because it is the type locality of canaphite. This mineral, described by Peacor, et al (1985) was attributed to “Haledon, NJ” with noted uncertainties. Steriss, et al (1987) indicated that the mineral actually originated from the Great Notch quarry. According to their note Steriss was the original collector.

The quarry exposes the lower part of the Orange Mountain (First Watchung) basalt.

Early Jurassic
174.1 - 201.3 Ma

ID: 2821781
Orange Mountain Basalt

Age: Early Jurassic (174.1 - 201.3 Ma)

Stratigraphic Name: Orange Mountain Basalt

Description: (Olsen, 1980) - Dark-greenish-gray to greenish-black basalt composed mostly of calcic plagioclase (typically An65) and clinopyroxene (augite and pigeonite); crystals are generally less than 1 mm (0.04 in) long. Consists of three major flows. The flows are separated in places by a weathered zone or by a thin, up to 3-m- (10-ft-) thick bed of red siltstone (not shown on map) or volcaniclastic rock. Lowest flow is generally massive and has widely spaced curvilinear joints; columnar joints in lowest flow become more common toward the northeast. Middle flow is massive or has columnar jointing. Lower part of the uppermost flow has pillow structures; upper part has pahoehoe flow structures. Tops and bottoms of flow layers are vesicular. Maximum thickness is about 182 m (597 ft).
