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: Shale breaks into thin pieces with sharp edges. It occurs in a wide range of colors that include red, brown, green, gray, and black. It is the most common sedimentary rock and is found in sedimentary basins worldwide. What is Shale?
Shale | Formation, Composition, Sedimentary | Britannica
Shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth.

Shale: Identification, Characteristics, and More - Rockhound …
To identify shale, first observe its grain size and ensure that no individual grains can be seen with the naked eye. Next, look for thin, parallel layers and note if the rock tends to break along those surfaces. Shale specimens usually have sharp edges, and it is common for fossils to be present.

Shale Definition & Meaning - Merriam-Webster
The meaning of SHALE is a fissile rock that is formed by the consolidation of clay, mud, or silt, has a finely stratified or laminated structure, and is composed of minerals essentially unaltered since deposition.
What is Shale? - AllTheScience
2024年6月4日 — Shale is a very common form of sedimentary rock found in deposits all over the world. It is distinguished by being soft and highly fissile. Shale has a number of ornamental and practical uses, in addition to being a rich source of fossil depositions which can provide information about different eras in Earth's geological history.
