glacial till

The striations are best preserved at the edge of freshly exposed glacial tills.

The northern end of the island is a flat plain, consisting of glacial tills and marine sediments.

It is named after the glacial tills found in the Karoo region of South Africa where evidence for this ice age was first clearly identified.

Glacial tills near the townsite of Westwold have provided fossils from the Sangamon interglacial period 130,000 years ago.

Derived from gneisses, sandstones and conglomerates the extensive glacial tills in Lewis have sandy loam textures.

Erie's bedrock is Devonian shale and siltstone, overlain by glacial tills and stratified drift.

Glacial tills and sands are the prominent geological features resulting in a relatively base-poor soil, characteristic of glacial drift geology.

This research found that at the type locations for the Kansan and Nebraskan tills numerous glacial tills, which were separated by numerous paleosols, existed.

The region of coastline is known as the Holderness Coast; geologically the land is formed of glacial tills (boulder clay), which are subject to coastal erosion.

Their rounded shape, whether found in glacial tills or glacial-fluvial (outwash) gravels, indicate that they were eroded from pre-existing littoral or fluvial deposits.

Dry Valley soils originate from weathering of bedrock and glacial tills that consist of granites, sandstones, basalts and metamorphic rocks.

Contrary to the interpretations of Baron von Toll and earlier geologists, glacial tills and related sediments are completely absent within Bolshoy Lyakhovsky Island.

An additional problem is that recent research demonstrates that the glacial tills, the Glasford Formation, of the Illinoian Stage are limited in age to Marine Isotope Stage 6.

Soil in Hamilton is predominately derived from glacial drift (glaciolacustrine sediments in the lower city; glacial tills in the upper city) and from limestone and shale erosion.

Glacial tills and residual soils in parts of the Lizard peninsula in Cornwall contain elevated levels of TiO&sub2;, as ilmenite, over thicknesses of several metres (Leake, personal communication May 1989).

As developed between 1894 and 1909, the Kansan Stage was based on a model that assumed that the Pleistocene deposits contained only two glacial tills and one volcanic ash bed within Nebraska and Kansas.

Detailed research by Boellstorff demonstrated that the two glacial tills and one ash bed stratigraphic model, on which the Yarmouthian, Kansan, Nebraskan, and Aftonian glacial - interglacial nomenclature was based, was completely wrong.

In addition, detailed studies of glacial tills in Kansas have found that at different outcrops, the same glacial till has been identified as being either a "Kansan" till or "Nebraskan" till.

The Illinoian Stage is defined as the period of geologic time during which the glacial tills and outwash, which comprise the bulk of the Glasford Formation, accumulated to create the Illinoian Glacial Lobe.

Successional dynamics beginning with colonization of an area that has not been previously occupied by an ecological community, such as newly exposed rock or sand surfaces, lava flows, newly exposed glacial tills, etc., are referred to as primary succession.

A publication by the New Brunswick Department of Natural Resources notes that the soils in Salisbury, made from calcareous sandstone and mudstone, are fine-textured and, when properly drained, "are the most fertile glacial tills" in the watershed.

In time, the stratigraphy of Pleistocene deposits was found to be far more complex then the two glacial tills and one volcanic ash bed on which the Yarmouthian, Kansan, Nebraskan, and Aftonian glacial - interglacial nomenclature was originally based.

Glacial erratics such as flint and rhomb porphyry, thought to originate from the Skagerrak and Oslo areas respectively, and deformed glacial tills found on the coast of Jæren provide the main onshore evidence for the Norwegian Channel Ice Stream.

The superficial geology in this area predominantly consists of Devensian glacial tills, which overlie the Middle and Upper Pennine Coal Measures; the same sequences of sandstones, mudstones and coal seams as forms the impressive coalfields of Lancashire.

Also, the "interglacial" deposits used by Leverett to originally define the Yarmouthian (Yarmouth) Interglacial in 1898 actually consist of interbedded glacial tills, diamictons, peats, sands, and silts, that are part of the Kellerville Till Member of the Glasford Formation.
