The Francisco Brothers Quarry was a small pit in the Orange Mountain (First Watchung) basalt, which was operated by J. H. and S.G. Francisco, between 1905 and 1922. It was the southern most good exposure of the pillow lavas in the lower part of the second flow unit of the OMB. This horizon is known to extend from the reservoir in Cedar Grove, NJ, just south of the Francisco Brothers quarry and where there were some small exposures during its construction around 1902, to the Prospect Park Quarry. It is important not just for the mineral specimens that it produced but because it was a prime field location for the geologists of a century ago, who were studying the basalts.

During the period of the 1890’s and up to 1905 the Francisco brothers operated 2 quarries described as being adjacent to each other. These operations were discontinued by 1905 and the quarry that is mineralogically well known was begun. However, Fenner (1908) indicates that at least one of the older Francisco Brothers pits was also in pillow lava.

Most descriptions of the location of this quarry are vague saying only that it was “near the railroad station at Great notch”. As nearly as this author can determine the 1905 – 1922 operation was about 900 feet southwest of the station. It is now represented by a small pond in a small patch of woods, an isolated island in a sea of suburban sprawl. On some air photos, taken at the right season, the right angle and at the right time of day, one can discern what appears to be old quarry faces in the woods on the southeast side of the pond. This is almost certainly the place. The location of the earlier pit(s) discussed by Fenner (1908) is still unknown. They were probably very small and shallow and seem to have been completely erased by tract housing.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

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).
