clastic rock that contains mostly silt-sized material, from 0.0039 to 0.062 mm.
A fine-grained sedimentary rock composed mainly of silt, intermediate in grain size between sandstone and shale, lacking the fissility of the latter.
A very fine-grained consolidated clastic rock composed predominantly of particles of silt.
type of fine grained sedimentary rock
Sedimentary rock made up of dominantly silt-sized particles.
sedimentary rock like shale but lacking in the tendency to split into layers.
a fine-grained, layered sedimentary rock composed primarily of grains between 1/256 mm and 1/16 mm in size. Siltstones tend to be "flaggy" and contain hard thin layers. They feel grittier than shales or mudstones.
An indurated silt having the texture and composition of silt but lacking its fine lamination or fissility; a massive mudstone in which silt predominates over clay; a non-fissile silt shale.
a fine-grained sandstone of consolidated silt
The consolidated equivalent of silt.
A rock whose grainsize composition is finer than sandstone but coarser than shale.
fine-grained sedimentary rock consisting of consolidated silt.
a very fine-grained rock composed primarily of silt-size grains
A rock made up of silt-sized particles.
sedimentary rock made mostly of silt-sized grains.
A sedimentary rock formed by consolidation of fine silt.
Siltstone - A sedimentary rock in which silt (1/256 to 1/16 millimeter in diameter) predominates over clay ( 1/256 millimeter in diameter).
A fine-grained sedimentary rock composed mostly of silt-size particles.
Fine-grained sedimentary rock generally composed of very small quartz grains.
Sedimentary rock composed of silt-size (0.004-0.06 mm) particles (i.e., silt is coarser than clay, but finer than sand and has a slightly gritty feel when rubbed between the fingers or placed between the front teeth and lightly ground). See: sedimentary rock
A rock integrated by lÃ©gamo hardened, a fine sedimentario material.
an exceptionally fine-grained sedimentary rock.
a very fine grained sedimentary rock, sometimes referred to as a shale
Similar to shale, but has greater than 2/3 silt and lacks the fine laminations.
(220) - Sedimentary rock consisting of fine-grained particles in the size range of 0.004 to 0.062 mm. Composed chiefly of clays and fine-grained quartz with mica.
a sedimentary rock made of silt-size particles cemented together.
Siltstone is a fine-grained type of sandstone that is made from silt
A sedimentary rock similar in composition to mudstone, but slightly coarser grained
A fine-grained, consolidated sedimentary rock, composed largely of silt-sized particles.
Siltstone is a geological term for a sedimentary rock whose composition is intermediate in grain size between the coarser sandstone and the finer mudstone.
