Till - Wikipedia
...Till, or glacial till, is unsorted glacial sediment. Till 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....

BGS Lexicon of Named Rock Units - Result Details
...Till 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). Synonym: boulder clay. Obsolete: pinnel....

What Is Till Soil? Glacial Deposits Explained - ScienceInsights
...Till soil is a type of geological deposit left behind by glaciers. It consists of a completely unsorted mix of particles, from fine clay and silt all the way up to sand, gravel, and boulders, all jumbled together without any layering or organization....

Till | Glacial Deposits, Sediments & Soils | Britannica
...Till, 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....

The engineering properties of glacial tills - ScienceDirect
...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....

Till, glacial deposits, Quaternary, Cainozoic of north-east Scotland
...Tills consist of ice-transported material laid down sub-glacially at the base of active glaciers and ice sheets, proglacially and supraglacially at the margins of retreating ice sheets, and paraglacially soon after glaciation when sediment deposited earlier is remobilised....

The engineering properties of glacial tills - Emerald Insight
...Glacial tills, which are extensive throughout the temperate zone, are complex, hazardous soils that are spatially variable in composition, structure, fabric and properties, making them very difficult to sample, test and classify (Clarke, 2017; Griffiths and Martins, 2017)....
