Silt

Silt is granular material of a size somewhere between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil or as sediment mixed in suspension with water (also known as a suspended load) in a body of water such as a river. It may also exist as soil deposited at the bottom of a water body. Silt has a moderate specific area with a typically non-sticky, plastic feel. Silt usually has a floury feel when dry, and a slippery feel when wet. Silt can be visually observed with a hand lens.

Sources

Silt is created by a variety of physical processes capable of splitting the generally sand-sized quartz crystals of primary rocks by exploiting deficiencies in their lattice. These involve chemical weathering of rock and regolith, and a number of physical weathering processes such as frost shattering and haloclasty. The main process is abrasion through transport, including fluvial comminution, aeolian attrition and glacial grinding. It is in semi-arid environments that substantial quantities of silt are produced. Silt is sometimes known as "rock flour" or "stone dust", especially when produced by glacial action. Mineralogically, silt is composed mainly of quartz and feldspar. Sedimentary rock composed mainly of silt is known as siltstone.

Silt (album)

Silt is the debut album by Mistle Thrush, a Boston, Massachusetts-based band. It was released in 1995 on CD by Bedazzled (catalog #BDZ26). The previous year, the band released a five-song EP titled Agus Amàrach. The band didn't release another full-length album until 1997's Super Refraction. Silt saw original guitarist Brad Rigney (departed to Big Monster Fish Hook) replaced by former teenage hardcore semi-star, Matthew Kattman (ex-Funny Wagon/Kingpin).
