SHALE Meaning and Definition

  1. Shale is a type of fine-grained sedimentary rock that is composed primarily of compacted and hardened clay and silt particles. It is characterized by its laminated or layered structure, with individual layers often referred to as "shale beds." Shale typically has a smooth texture and can exhibit various colors, including shades of gray, brown, black, and occasionally green.

    The formation of shale occurs over long periods, as layers of sediment settle on the ocean or lake floor. Over time, the weight of the overlying sediments compresses the lower layers, causing them to become compacted. This compaction, combined with the presence of water and the natural cementing of particles, results in the hardening and solidification of the shale rock.

    Shale is known for its low permeability, meaning it does not allow the easy flow of fluids through its pores or fractures. This property has significant implications for industries such as oil and gas production, as it can restrict the movement and extraction of hydrocarbons trapped within the rock.

    Furthermore, shale has become a key source for unconventional oil and natural gas extraction through a process called hydraulic fracturing, or fracking. This involves creating fractures in the shale using pressurized fluids to release trapped hydrocarbons.

    In addition to its economic significance, shale also holds geological importance, as it often contains fossils and detailed records of past environments, providing valuable insights into Earth's history and the evolution of life.

  2. A shell or husk; in geol., argillaceous strata that exhibit a laminated structure, and split into irregular plates-some varieties being bituminous, others calcareous, arenaceous, &c.

Etymology of SHALE

The word "shale" is derived from the Old English word "scealu", which means "shell" or "husk".

This connection originally referred to the easily breakable quality of shale rock, compared to other types of rock. Over time, the term "shale" became specifically associated with the fine-grained sedimentary rock composed of mud or clay particles that can be split into thin layers.
