It typically breaks into thin flat pieces. Shale is typically formed on the floor of the ocean and lakes, and may include some organic material. These tiny grains are usually clay minerals such as illite, kaolinite, and smectite. However, there are more precise names within these broader categories that are based on clastic sediment features other than grain size.  Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility. Its grains are often so small that they cannot be seen without a microscope. Clastic Sedimentary Rocks. Most rocks that form from fragmental rock particles. foliated phyllite. The famous White Cliffs of Dover consist of chalk, a type of limestone.

Common in some Paleozoic and Mesozoic strata, black shales were deposited in anoxic, reducing environments, such as in stagnant water columns. This is a red shale with greenish mottling. Although these are sand-sized, the bulk of the rock is silt- and clay-sized and thus is a shale. Shale is a clastic sedimentary rock, composed mainly of small clay minerals, derived from the weathering of felsic igneous rock. Sandstone is composed of sand. Rocks with similar particle sizes but with less clay (greater than 2/3 silt) and therefore grittier are siltstones. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone. Clastic sedimentary rocks are made up of pieces of other rocks. Q. Graywacke clastic. SURVEY . SHALE.

In the context of underground coal mining, shale was frequently referred to as slate well into the 20th century. They typically form in environments where muds, silts, and other sediments were deposited by gentle transporting currents and became compacted, as, for example, the deep-ocean floor, basins of shallow seas, river floodplains, and playas. Non-clastic textures are found chiefly in rocks that have precipitated chemically from water (chemical sedimentary rocks), such as limestone, dolomite and chert. Addition of variable amounts of minor constituents alters the color of the rock. Shale is considered a fissile rock because it splits very naturally along its layers. clastic organic sandstone. Sedimentary. Shale. Non clastics are typically carbonate rocks, composed chiefly of calcium carbonate, is, the shells of other organisms. The common names of clastic sedimentary rocks—conglomerate, sandstone, siltstone, and shale—are based solely on grain size.
