Till - Wikipedia
WEBTill is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes.

WEBTill, in geology, unsorted material deposited directly by glacial ice and showing no stratification. Till is sometimes called boulder clay because it is composed of clay, boulders of intermediate sizes, or a mixture of these.

7.12: Glacial Deposits - Geosciences LibreTexts
WEBDec 26, 2021 — Till is a genetic term applied to all unstratified and unsorted deposits made directly by or from glacier ice. The lithified equivalent of till, as seen in the ancient sedimentary record, is called tillite. Till is subdivided in turn into lodgement till and ablation till (Figure 7-47).
Glacial Till and Glacial Flour - U.S. National Park Service
WEBFeb 22, 2018 — Glacial flour is that smallest size of sediment (much smaller than sand) and is responsible for the milky, colored water in the rivers, streams, and lakes that are fed by glaciers. A road cut through a moraine in Yellowstone National Park exposes the …

The engineering properties of glacial tills - Geotechnical Research
WEBDec 19, 2018 — An overview of the formation of glacial tills and their properties shows that they are composite soils which should be classified according to their lithology, their mode of deposition to link the glacial processes with the facies characteristics and their engineering behaviour.

The BGS Lexicon of Named Rock Units - British Geological Survey
WEBTill is unsorted and unstratified drift, generally overconsolidated, deposited directly by and underneath a glacier without subsequent reworking by water from the glacier. It consists of a heterogenous mixture of clay, sand, gravel, and boulders varying widely in size and shape (diamicton).
