A mass or heap of anything arranged like a bed; as, a bed of ashes or coals.
A layer or seam, or a horizontal stratum between layers; as, a bed of coal, iron, etc.
The superficial earthwork, or ballast, of a railroad.
It is a layer or sheet of the rock mass that is horizontal, usually curved and lenticular, as developed by fractures. Sometimes the term is also applied to the surface of parting between sheets.
A prepared heap of thatching material from which materials are pulled to remove unwanted material and ensure the stems are parallel.
Deposition layer in sedimentary rock. In walling, the flattish base of a stone or any plane along which it splits readily.
(geology) a stratum of rock (especially sedimentary rock); "they found a bed of standstone"
a stratum of ore or coal thick enough to be mined with profit; "he worked in the coal beds"
a foundation of earth or rock supporting a road or railroad track; "the track bed had washed away"
A stratum of coal or other sedimentary deposit.
A random heap of thatching material from which straws are pulled to remove unwanted rubbish and ensure the stems are parallel
a distinct rock unit in a stratigraphic sequence.
The smallest division of stratified layers marked by more or less well-defined divisional planes.
It is a deposit of granular rock which is the result of the erosion of solid rock.
that portion of an outcrop or face of a quarry which occurs between two bedding planes.
A stratum or layer in a sedimentary rock sequence, or unconsolidated sediment.
a layer of sediment turned to rock
(1) In granites or marbles, a layer or sheet of the rock mass that is horizontal, commonly curved and lenticular, as developed by fractures. Sometimes applied also to the surface of parting between sheets. (2) In stratified rocks, the unit layer formed by sedimentation; of variable thickness, and commonly tilted or distorted by subsequent deformation; generally develops a rock cleavage, parting, or jointing along the planes of stratification. (3) The top or bottom of a joint, or natural bed/surface of stone parallel to its stratification.
A layer of sedimentary rock, distinguishable from layers above and below.
A centimetre to decimetre layer in a stratigraphy. Beds can be massive or contain structures, such as cross bedding, ripple marks or laminations. Beds are grouped into formations. ... More
The result of the chopping operation. A mat of chopped glass fibers that is deposited onto a layer of resin mix on a carrier film under the chopper.
a layer of sediment or sedimentary rock
a layer of rock, usually sedimentary or volcanic.
A single layer of sedimentary rock or a single stratum
Layer of sedimentary rocks or sediments bounded above and below by bedding surfaces. Bedding surfaces are produced during periods of nondeposition or abrupt changes in depositional conditions, including erosion. Bedding surfaces are synchronous when traced laterally; therefore, beds are time-stratigraphic units. See Campbell, 1967 (Sedimentology 8:7-26) for more information.
A layer of rock or mineral.
Sedimentary structure that usually represents a layer of deposited sediment.
A subdivision of a stratified sequence of rocks, lower in rank than a member or formation, internally composed of relatively homogeneous material exhibiting some degree of lithologic unity, and separated from the rocks above and below by visually or physically more or less well defined boundary planes.
In geology a bed is the smallest division of a geologic formation or stratigraphic rock series marked by well-defined divisional planes (bedding planes) separating it from layers above and below. A bed is the smallest lithostratigraphic unit, usually ranging in thickness from a centimeter to several meters and distinguishable from beds above and below it. The term is generally applied to sedimentary strata, but may also be used for volcanic flows or ash layers.
