A wind blown deposit or parent material. Mainly silt. Often formed by wind action on dried-up glacial lake beds.
An aeolian deposit of angular sand-, silt- and clay-sized particles.
Unconsolidated, silt-sized particles with accessory clay and sand particles that are deposited primarily by the wind. Loess that has filtered down into cracks in the lava and between the cinders provides the growth medium for vegetation.
A load of silt that is produced by the erosion of outwash and transported by wind. Much loess found in the Mississippi Valley, China, and Europe is believed to have been deposited during the Pleistocene Epoch.
a widespread windblown deposit of dust, usually of silt-sized rock or mineral fragments. The fragments are usually held together weakly by a limy cement.
1.)Unconsolidated, wind-deposited silt and dust. 2.)An extremely fertile, fine-grained loam composed of quartz, feldspar, hornblende, mica, and clay; deposited by the wind during the Pleistocene Age. It originates in arid regions from glacial outwash (Morris 1992).
A wind blown, uniform fine-grained soil.
Deposits of silt laid down by aeolian processes over extensive areas of the mid-latitudes during glacial and postglacial times.
a soil where wind has deposited clay and silt; Austria and Germany in particular.
Material transported and deposited by wind and consisting primarily of silt size particles.
A buff-colored, wind-blown deposit of fine silt, which is frequently exposed in bluffs with steep faces. The thickness can range from 6 to 30 m. The loess of the USA and Europe is thought to be the fine materials first transported and deposited by the waters of melting ice sheets during the glacial period. It was later blown considerable distances with, in some cases, deposition in lakes. The origin of Asiatic loess, however, is apparently wind-blown dust from central Asian deserts.
An unstratified, wind-deposited, dusty sediment rich in clay minerals.
A homogeneous, unstratified accumulation of silt-sized material deposited by the wind.
Unconsolidated, wind deposited sediment composed largely of silt-sized quartz particles (0.015-0.05 mm diameter) and showing little or no stratification. It occurs widely in the central USA, northern Europe, Russia, China, and Argentina. In all but China, it is evidently derived largely from reworked glacial outwash deposits.
A soil made up of small particles that were transported by the wind to their present location.
an unstratified, buff- to yellow-brown, loamy clay originating in arid regions and transported by the wind.
A form of wind-blown silt or dust.
a blanket of windblown silt.
a fine-grained unstratified accumulation of clay and silt deposited by the wind
A clay, consisting of fine rock-flour (mainly quartz) that originates in arid regions and is transported by wind.
silt deposited by winds blowing across sparsely vegetated ground during the last Ice Age; mantles many plains, terraces and downs in the eastern South Island and southern North Island.
Non-stratified silt, clay, and dust, originating as glacial sediment, but re-deposited by wind. Wind-blown silt.
sedimentary deposits of fine grained windblown dust often originating from the last Ice-Age.
Wind born dust derived from rock exposed around ice sheets during the Ice Ages.
Windblown glacial deposits, often covering vast areas. Made up largely of silt size, angular particles, with strong water holding ability. Extremely fertile and a major contribution to the highly productive agricultural lands of the Midwest to the south.
An unconsolidated sediment composed chiefly of silt-sized particles laid down by the wind.
a wind blown deposit of silty soil having little or no stratification. List of Glossary Terms
A wind-blown deposit of sediment made mostly of silt-sized grains.
Material transported and deposited by wind and consisting of predominantly silt-sized particles.
A wind-carried deposit consisting of very small sediments.
Layers of fine-grained sediments deposited from the wind.
(approx: luss) A blanket deposit of buff-colored calcareous silt, homogeneous, non-stratified, weakly coherent, porous, and friable. A rude vertical parting allows it to stand in steep or vertical faces. Loess covers wide areas in Northern Europe, eastern China, and the Mississippi Valley. It is considered to be windblown dust of the Pleistocene age.
A wind-deposited sediment consisting mostly of silt, the silt commonly derived from finely ground rock washed out of continental glaciers.
n. A widespread, loose deposit consisting mainly of silt; most loess deposits formed during the Pleistocene as an accumulation of wind-blown dust carried from deserts, alluvial plains, or glacial deposits.
An unstratified, usually buff to yellowish brown, loamy deposit created by fine mineral particles carried by the wind. Pronounced "less."
silt-sized sediment which mantles uplands in deserts and periglacial regions. Represents wind-blown (aeolian) dust deposits.
A marly deposit of recent (Post-Tertiary) date, which occupies a great part of the valley of the Rhine. 114
Fine grained material, dominantly of silt-sized particles, deposited by the wind.
Windblown silt* and fine sand* that collects on the lee sides of ridges at higher elevations within the Pasco Basin.
An unstratified, usually buff to yellowish brown, loamy deposit found in North America, Europe, and Asia and believed to be chiefly deposited by the wind ( Merriam-Webster Online).
Fine-grained soil material, consisting predominately of silt-sized particles, deposited by wind. Loess soils are usually well drained.
(Pronunciation: "LESS") A yellowish brown, earthen material whose low clay content prevents distortion during drying and firing.
A deposit of windblown sand and clay weakly cemented by calcite.
Nonstratified sediment composed of silt-sized particles deposited by the wind. These windblown dust deposits were derived from glacial materials. Loess is found throughout Kansas but is especially common in the northeastern and northwestern parts of the state.
A uniform, porous, fine-grained, wind-blown deposit consisting predominantly of silt-sized particles, with smaller amounts of clay and fine sand. While the classical loesses of Europe, North America and China are commonly calcareous, most New Zealand loesses, being derived from greywacke detritus, are not.
a homogenous, nonstratified, deposit consisting predominantly of silt, with subordinate amounts of very fine sand and/or clay. AGI
a yellowish-brown marl or loam, usually deposited by the wind. [AHDOS
lO es, les, lus] Fine grained soil deposited in Ordos bend by winds from central Asia; created fertile soil for sedentary agricultural communities. (p. 63)
Loess is the term for soil particles that have been moved to another location by the wind.
Among the classifications of soil types, loess, from the German Löss, and ultimately from Swiss German lösch, loose; pronounced in several different ways in English (IPA: ]), it is a fine, silty, windblown (eolian) type of unconsolidated deposit; sometimes the term refers to the soil derived from it. It is derived from glacial deposits, where glacial activity has ground rocks very fine (rock flour). After drying, these deposits are highly susceptible to wind erosion, and downwind deposits may become very deep, even a hundred metres or more, as in areas of China and the midwestern United States.
