Shale - Wikipedia
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g., kaolin, Al 2 Si 2 O 5 4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. [1]
Shale: Sedimentary Rock - Pictures, Definition & More - Geology.com
Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." Shale is distinguished from other mudstones because it is fissile and laminated.

2023年8月21日 · Shale is a laminated or fissile clastic sedimentary rock that composed of predominance of silt and clay other minerals, especially quartz and calcite. Characteristic properties of shale is breaks along thin laminae or parallel layering or bedding called fissility. It is most abundant sedimentary rock.

Shale: Identification, Characteristics, and More
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.
