In geology and related fields, a stratum (pl.: strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either bedding surfaces or bedding planes. [1]
stratum, sedimentary rock layer bounded by two stratification planes, the latter being produced by visible changes in the grain size, texture, or other diagnostic features of the rocks above and below the plane.
21 Φεβ 2023 · A stratum is a rock layer with a lithology (texture, color, grain size, composition, fossils, etc.) different from the adjacent ones and several form strata. Each stratum is separated by a visible bedding surface or plane.
STRATUM definition: 1. one of the parts or layers into which something is separated: 2. a layer of rock, soil, or…. Learn more.
stratification, the layering that occurs in most sedimentary rocks and in those igneous rocks formed at the Earth’s surface, as from lava flows and volcanic fragmental deposits. The layers range from several millimetres to many metres in thickness and vary greatly in shape.
A stratum is a distinct layer of rock or sediment that has formed over time, often representing a specific period in geological history. Strata can vary in thickness, composition, and fossil content, which can provide important clues about the Earth's past environments and biological evolution.
