Shale Rock: Geology, Composition, Uses
Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth's crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.
Shale vs Clay: Differences And Uses For Each One
Shale is a sedimentary rock, while clay is a type of soil or sediment. Shale is often used as a source of oil and gas, while clay is used in ceramics and pottery. Shale can be more stable and durable than clay for building purposes. Precise language use is important for clear communication.
Oil Shale
OIL SHALE. Shale is a fine-grained sedimentary rock composed of a mud rich in clay- and silt-sized sediment grains. Some shale can also contain significant amounts of organic matter—the fossil remains of protozoans, microscopic animals, or plants—called kerogen. When kerogen-bearing shale is buried deeply enough and for millions of years ...
Shale: Sedimentary Rock
Shale is a rock composed mainly of clay-size mineral grains. These tiny grains are usually clay minerals such as illite, kaolinite, and smectite. Shale usually contains other clay-size mineral particles such as quartz, chert, and feldspar. Other constituents might include organic particles, carbonate minerals, iron oxide minerals, sulfide ...
