Unstratified sediment deposited by a glacier; generally does not yield a good supply of water to a well.
An unstratified or crudely stratified glacial deposit consisting of a stiff matrix of fine rock fragments and and old soil containing sub-angular stones of various sizes and composition, many of which may be striated (scratched). It forms a mantle from less than 1 m to over 100 m in thickness covering areas which carried an ice sheet or glaciers during the Pleistocene and Holocene periods.
A deposit of unsorted angular fragmentys of rock left by a glacier.
the mixture of sediments (rocks, sand, clay, and soil) of various sizes deposited by a glacier as it melts.
An unstratified and unconsolidated sediment deposited by glaciers.
Unstratified glacial and fluvioglacial deposits left after the retreat of glaciers and ice sheets; consists of clay, sand, gravel, and boulders intermingled in any proportion.
any sediment that is transported and deposited by a glacier without being sorted by meltwater. It consists of clay, sand and large rock fragments that are deposited in irregular sheets or in ridges called moraines.
A mixture of unsorted mud, sand, pebbles, and larger rocks deposited by glaciers.
Till - Unsorted, unstratified glacial deposits consisting mainly of silt and clay but also containing sand, gravel, cobbles, and boulders.
Dominantly unsorted and unstratified drift, generally unconsolidated deposited directly by and underneath a glacier without subsequent reworking by meltwater, and consisting of a hetergeneous mixture of clay, silt, sand, gravel, stones, and boulders.
Dense heterogeneous mixture of fine-grained and coarse-grained material of glacial origin and compaction. It often contains significant quantities of boulders and cobbles. See Glacial Till and Hardpan.
sand, gravel, and rocks carried and deposited by a glacier.
unsorted chaotic deposit of rocks deposited by a glacier
debris deposited directly by melting ice in a glacier.
Sediment laid down directly from ice, either underneath or at the margins of ice bodies. Till usually consists of a wide range of sediment from boulders to mud.
Till is a poorly-sorted sediment, containing particles ranging from clay- to boulder-size, that is deposited directly by glacial ice.
mixture of rock fragments ranging in size from clay to boulders, deposited beneath moving glacial ice or from the melting of glacial ice
An unsorted sediment deposited directly by a glacier and not reworked by meltwater.
An unconsolidated sediment containing all sizes of fragments from clay to boulder deposited by glacial action, usually unbedded.
Unconsolidated, nonsorted, unstratified drift deposited by and underneath a glacier and consisting of a heterogenous mixture of different sizes and kinds of rock fragments.
glacial drift composed of an unconsolidated, heterogeneous mixture of clay, sand, pebbles, cobbles, and boulders
(or "glacial till"): Deposits of a glacier - usually described as massive (not layered), poorly-sorted, and composed of multiple types of angular to sub-rounded rocks, but varying greatly with source material.
Unsorted, unstratified rock debris composed of a wide range of particle sizes that was deposited directly by and underneath a glacier.
unstratified soil deposited by a glacier; consists of sand and clay and gravel and boulders mixed together
a stiff unstratified clay mixed with sand , gravel and boulders
An unsorted and unstratified accumulation of glacial sediment, deposited directly by glacier ice. Till is a heterogeneous mixture of different sized material deposited by moving ice (lodgement till) or by the melting in-place of stagnant ice (ablation till). After deposition, some tills are reworked by water.
The unsorted mixture of sediment carried or deposited by a glacier. Also known as " glacial drift".
Nonsorted, nonstratified sediment carried or deposited by a glacier.
Unstratified drift, deposited directly by a glacier without reworking by meltwater, consisting of a mixture of clay, silt, sand, gravel, and boulders ranging widely in shape and size.
A glacial deposit, consisting of a wide range of sizes of chunks of rock and fine-grained, throughly-ground-up rock-flour, that ultimately lithifies to form a consolidated, poorly-sorted rock. It is a sediment laid down by glacial ice, without the intervention of water.
glacier deposits composed primarily of unsorted sand, silt, clay, and boulders laid down directly by the melting ice
Unsorted sediments laid down directly by glacier ice without the intervention of water
chaotic mix of clay and boulders deposited by glaciers during the last Ice Age.
Loose sediment deposited by glaciers.
that part of a glacial drift consisting of material deposited by and underneath the ice, with little or no transportation and sorting by water. It is generally unstratified, unconsolidated heterogeneous mixture of clay, sand, gravel and boulders.
Unsorted, unstratified rock rubble or debris carried on and/or deposited by the ice of a glacier
Deposit from a glacier of unsorted rocks, boulders, gravel and sand (glacial drift).
unstratified and unsorted material deposited directly by a glacier.
a stiff clay full of stones of varying size. Is used today to denote non-sorted clays, silts and sands carried by glaciers and deposited on the landscape during retreat (glacial till).
a deposit of sediment formed under a glacier, consisting of an unlayered mixture of clay, silt, sand, and gravel ranging widely in size and shape
Unsorted sediment deposited directly from glacier ice with little or no reworking by meltwater or mass movement. Usually contains particles ranging in size from clay to boulders, and may be partially consolidated depending on the geologic history. See: mudflow
An unstratified and poorly sorted sediment containing all sizes of fragments from clay to boulders, deposited by glacial action.
A general term for the rocks and material left behind after glacial retreat.
Glacially transported and unconsolidated material deposited directly by ice, without having been reworked by melt-water. Material size varies widely and can range from clay to boulders.
rock material released from a moving glacier.
A glacial soil consisting of rock debris, sand, silt, clays and boulders.
sediments laid down directly by glacial ice. Commonly consists of unsorted angular rock fragments mixed with clay.
POORLY SORTED and generally unstratified sediments, deposited directly by and underneath a glacier. Usually very hard and compact, with good bearing capacity and low permeability.
n. unstratified glacial drift consisting of clay, sand, gravel, and boulders
Unstratified glacial drift consisting of sand, clay and gravel with intermingled boulders.
A random mixture of finely crushed rock, sand, pebbles, and boulders deposited by a glacier.
general term refering to any kind of sediment deposited directly from glacier ice with little or no influence by running water; typically unstratified and unsorted; sometimes called boulder-clay. May originate in various manners: lodgement (basal) till is deposited below active ice, ablation till is let down to the ground by melting of stagnant ice, and flow till forms as mudflows off the edge of stagnant ice.
A non-sorted or poorly sorted sediment containing a wide range of particle sizes deposited by glacier ice. There are several kinds of till, determined by the mode of deposition.
Heterogeneous sediment deposited directly by a glacier. The particles within this deposit have not been size sorted by the action of wind or water.
is the unsorted rock debris deposited directly by the glacier without the extreme reworking by meltwater. Also called: Glacial till.
Drift that is deposited directly from glacial ice and therefore not sorted.
a glaciogenic, surficial deposit composed of unsorted clay, sand and matrix-supported rock fragments.
