the boundary between two stratified rock layers

A layer in a series of sedimentary beds that marks a change in the type of deposits.

surface parallel to the surface of a deposition of sediment. In shales, the rocks split along the bedding plane; in some sandstones however, the split is marked by changes in colour and grain size.

Horizontal plane of sedimentary stone in the position of its original formation.

A surface parallel to the surface of deposition, which may or may not have a physical expression. The original attitude of a bedding plane should not be assumed to have been horizontal. See also CROSS-BEDDING.

The bedding plane is the surface that separates one layer (or bed) of sedimentary stone from another.

Surface separating layers of sedimentary rocks and deposits. Each bedding plane marks termination of one deposit and beginning of another of different character, such as a surface separating a sandstone bed from an overlying mudstone bed. Rock tends to breaks or separate, readily along bedding planes.
