In a few places quartzite of Cambrian age may be mapped with the Belt series or quartzite of Belt age with the Cambrian rocks. Upper regressive lake margin, playa lake, and mudflat deposits are light- to dark-gray silty mudstone to argillitic siltstone or very fine grained sandstone, mostly thick bedded to massive, with desiccation cracks, intraformational breccias, faint wavy laminations, burrows, euhedral pyrite grains, and dolomite or calcite specks. Composite thickness of all Pre-Illinoian till may be up to 1,000 ft (305 m). Correlation of these sediments to the formations of the Hawthorn Group exposed to the east and in the subsurface is uncertain. However, it crops out or is near the surface is an area too small to be shown on a map of this scale. Bryn Mawr Formation - Red and brown quartz sand with silt, clay and fine gravel. Erosional unconformity at top. Tuscaloosa Group undifferentiated - Light-gray to moderate-reddish-orange clayey, gravelly fine to very coarse sand; massive mottled sandy clay; local wood and leaf beds; and thin beds of indurated sandstone.

Silurian(?) Jurassic) - Dark-gray to greenish-gray (weathers brown or gray), medium- to fine-grained, commonly porphyritic, generally massive with well-developed columnar jointing, grading from basalt near contacts to fine-grained gabbro in the interior, composed of plagioclase and pyroxene with accessory opaques and locally devitrified glass, quartz, or olivine. Sand ranges from massive to locally crossbedded and locally has fine organic matter. The Navesink and Red Bank deposits represent a transgressive (Navesink)-regressive (Red Bank) cycle of sedimentation (Owens and Sohl, 1969). Deposits are moderately to strongly consolidated, and commonly contain coarser grained sediment than younger deposits in the same area. MADISON GROUP--Group includes Mission Canyon Limestone (blue-gray massive limestone and dolomite), underlain by Lodgepole Limestone (gray cherty limestone and dolomite). Ordovician-Early(?) Includes older alluvium of Smith and others (1982) in the Klamath Mountains and both high- and low-level terraces along Oregon coast. reason. Superimposed on these landforms are swarms of Carolina bays. Undivided pre-Cenozoic metasedimentary and metavolcanic rocks of great variety. On these is placed 40 inches of fine sand. Not approved for concrete sand This material is not be a complete replacement of concrete sands in mix designs. Limestone, black, gray and green; micritic to coarse grained; thin bedded to concretionary with marine fossils common in lower half of interval; thin to medium bedded, nonmarine limestone common in upper half of unit. The transition to the underlying Sandy Hook Member occurs within several feet and is characterized by an increase in clay, quartz, silt, mica, and fine pieces of wood downward. Thickness 1,000 to 8,000 feet. Petters (1976) proposed a new formation, the Bass River Formation, which included the Raritan as well as the lowermost part of the Magothy and the uppermost part of the Potomac Formation, unit 3. These beds are mainly sand, as are those at Cliffwood Beach, but they tend to have more crossbedding than the typical Cliffwood strata and no burrows or marine fossils. [1967]). South Amboy Fire Clay Member - Basal member of the Magothy Formation. Thickness generally less than 30 feet. Clay layers are also common and some lower delta plain deposits form commercial kaolin bodies. Conc. FLATHEAD SANDSTONE--Dull-red quartzitic sandstone.

SHALE, CHERT, AND MINOR AMOUNTS OF QUARTZITE, GREENSTONE, AND LIMESTONE-Includes units such as Vinini Formation of north-central Nevada, Palmetto Formation in southern and central parts of Esmeralda County, and Comus Formation in Humboldt County. The Wildwood subcrops beneath surficial deposits where the Belleplain Member and Cohansey Formation were stripped away. Most Belleplain sand is quartz with lesser amounts of feldspar and mica. WHITEWOOD DOLOMITE, AND WINNIPEG AND DEADWOOD FORMATIONS (northeast Wyoming). The Woodbridge is approximately 20 m (66 ft) thick in the vicinity of Sayreville, Middlesex County, where the South River has stripped away the overlying Magothy Formation, and it crops out in many places in the Perth Amboy and New Brunswick quadrangles to the north, but not in the quadrangles to the south or southwest.

In some areas, planar bedding is well developed in sections that have abundant marine burrows (mostly the clay-lined trace fossil Ophiomorpha nodosa). CLINTON- Reddish-brown shale with some thin, greenish-gray siltstone and orange-brown sandstone and siltstone beds; thickness, about 500 feet. The age of the Shiloh is early Miocene (Burdigalian) as determined from diatoms. Exhibits a distinctive weathered, dissected surface. Thickness up to 150 ft (46 m). The formation is best exposed in the central sheet from the Fort Dix Military Reservation, Burlington County, southwestward to the Medford Lakes quadrangle. Thickness, 20 to 40 feet. It contains significant amounts of clay, silt and gravel which may occur as beds and lenses and may vary considerably over short distances. The South Amboy is a dark, massive to finely laminated clay, locally oxidized to white or red.
