Some black shale contains organic compounds that can be converted to oil or natural gas. Other colors of shale are crushed and mixed with water to create clay.Shale is a type of sedimentary rock, a rock formed either from the remains of organic creatures or from shattered pieces of older rocks. In shale’s case, layers of ancient silt and mud underwent extreme pressure that compounded them into thin sheets of striated rock. Shale is strong but brittle. It easily breaks into jagged shards.Shale oil, in fossil fuel production, either a synthetic crude oil that is extracted from oil shale by means of pyrolysis or a naturally occurring crude oil that is extracted from underground shale deposits by means of fracking (hydraulic fracturing). In the extraction of oil from oil shales,Shale is similar to siltstone but with even finer grain size, less than 1/256 of a millimeter in diameter. It is a very common sedimentary rock. It is composed of silt or clay. This is very fine particles of weathered and deconposed rock. What size particles make up shale? Geologists are specific about the definition of the rock called “shale.”

Shale is a fine-grained sedimentary rock composed primarily of clay minerals and other clay-sized particles of minerals like quartz and calcite. It is laminated and fissile, easily breaking along bedding planes. Shale forms from the deposition and compaction of clay-sized minerals in a low-energy environment.

Shale is a sedimentary rock formed from clay and silt, while slate is a metamorphic rock formed from shale or clay. Shale has a layered structure and is rich in organic matter, while slate has a fissile texture and is highly compressed and durable. Shale is softer and less durable than slate, which makes it more prone to weathering and erosion ...Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Shale is 3 whereas its compressive strength is 95.00 N/mm 2. Streak is the color of rock when it is crushed or powdered.Shale can be fairly hard if it has a silica cement, making it closer to chert. Typically, it is soft and easily weathers back into clay. Shale may be hard to find except in road cuts, unless a harder stone on top of it protects it from erosion. When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate.Oil Shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid organic material. Liquid and gaseous hydrocarbons can be extracted from the oil shale, but the rock must be heated and/or treated with solvents.
