The Ebbabreen ice−cored moraine area is covered with a sediment layer of up to 2.5 m thick, which mostly consists of massive diamicton. Due to undercutting by lateral streams, debris flow processes have been induced in marginal parts of this moraine.

Depositional dynamics in the El'gygytgyn Crater margin: implications for the 3.6 Ma old sediment archive [PDF]
The combination of permafrost history and dynamics, lake level changes and the tectonical framework is considered to play a crucial role for sediment delivery to El'gygytgyn Crater Lake, NE Russian Arctic.

Distinguishing characteristics of Diamictons at the Margin of the Matanuska Glacier, Alaska [PDF]
The origins of diamictons deposited at the Matanuska Glacier are identified in stratigraphic sequences mainly by the presence or absence of a pebble fabric, internal structure, and variation in gravel-size clast distribution. These properties correlate with major differences in depositional mechanisms and source material.

A glaciotectonic landform in the Shyok valley, Trans-Himalayan Karakoram Range, India
This study reports and discusses the first case of glaciotectonic landforms in the Shyok valley of the Trans-Himalayan Karakoram Range, Ladakh, where a large decomposed granite megablock (8.2 km2) along with underlying diamicton is thrust over the ...

The origin of water‐borne diamictons and their relation to turbidites [PDF]
Summary The term “diamicton” has recently been proposed as a non‐genetic name for any non‐calcareous terrigenous sediment containing a wide variety of grain sizes; the lithified equivalent is a “diamictite.” The present paper deals with the origin and classification of water‐borne diamictons. The latter have been divided by the writer

We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Late Wisconsinan Glacial Geomorphology of the Kent Interlobate Complex, Ohio, USA [PDF]
The northern sector of the Kent Interlobate Complex, created by twomajor ice lobes of the Laurentide Ice Sheet during late Wisconsinan times, dominates the glacial landscape of northeast Ohio.
