Cherty limestone
consists of stromatolitic and cherty limestones (Table 1). Further, Shrivastava recognized three mapable units; Pokran boulder bed, Sonia shale (salt psuedomorph shale) and Bandero limestone as formal members of the Jodhpur Formation. According to Shrivastava (1971) the red beds of the western Rajasthan, previously called as •VindhyanChert--Commonly called flint, chert is a fine-grained, microcrystalline sedimentary rock made up of silicon dioxide (SiO2)--the same chemical formula as the mineral quartz. Usually found as rounded nodules in limestone and dolomite or, less often, an extensive layered deposit, chert is harder and more resistant to erosion than limestone.

Very thick calciruditic and pebbly limestone bodies are interbedded in the cherty limestone, in turn newly overlain by marls and shales, followed by thin bedded mudstone. Four fusulinid ...Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges.The contact where described in two measured sections is a cherty, locally fossiliferous limestone and dolomite (Kaibab) that is overlain by a 42+ ft thick chert pebble conglomerate interbedded with yellow-gray sandstone and mudstone (Black Dragon) or by a yellow-gray micaceous mudstone and siltstone (Black Dragon).

Dolostone (Limestone) The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg (CO3)2). Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock. Their color is typically some shade of ...Shale and interbedded limestone. Shale is gray, green, red, reddish brown, or maroon, sandy, calcareous, fossiliferous, locally fissile; several fissile black shale beds are in lower 75 feet. Interbedded dark- to light-gray, medium- to thick-bedded, argillaceous, cherty limestone beds are very fossiliferous and locally contain shale partings.

Some of the gullies are deep enough to expose even older Pennsylvanian-age layers of cherty limestone, sandstone, siltstone, and shale known as the Paradox Formation. Between these cut valleys are erosion-resistant, upward-pointing triangles of rock called “flatirons.”Geology: The Boone Formation consists of gray, fine- to coarse-grained fossiliferous limestone interbedded with chert. Some sections may be predominantly limestone or chert. The cherts are dark in color in the lower part of the sequence and light in the upper part. The quantity of chert varies considerably both vertically and horizontally.
