The Helsingør diamicton

open access: yesBulletin of the Geological Society of Denmark, 1987
Deglaciation sequences comprising glaciolacustrine sediments overlain by till deposited in a subaqueous environment around the Danish coast of 0resund and in central Northeast Sjrelland are grouped into five facies (a, b, c, d and e ). Facies a and facies bare clays deposited from suspension fall out in ice dammed la­kes.

Middle and Late Pleistocene environmental history of the Marsworth area, south-central England [PDF]

open access: yes, 2014
To elucidate the Middle and Late Pleistocene environmental history of south-central England, we report the stratigraphy, sedimentology, palaeoecology and geochronology of some deposits near the foot of the Chiltern Hills scarp at Marsworth ...

Asynchronous glacier dynamics during the Antarctic Cold Reversal in central Patagonia [PDF]

open access: yes, 2018
We present 14 new 10Be cosmogenic nuclide exposure ages quantifying asynchronous readvances during the Antarctic Cold Reversal from glaciers in the Baker Valley region of central Patagonia.

The sedimentary legacy of a palaeo-ice stream on the shelf of the southern Bellingshausen Sea: Clues to West Antarctic glacial history during the Late Quaternary [PDF]

open access: yes, 2010
A major trough ("Belgica Trough") eroded by a palaeo-ice stream crosses the continental shelf of the southern Bellingshausen Sea (West Antarctica) and is associated with a trough mouth fan ("Belgica TMF") on the adjacent continental slope.

Sedimentological characteristics of debris flow Deposits within ice−cored moraine of Ebbabreen, central Spitsbergen

open access: yesPolish Polar Research, 2015
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]

open access: yesClimate of the Past, 2012
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.

The Middle Pleistocene glacial evolution of northern East Anglia, UK: a dynamic tectonostratigraphic-parasequence approach [PDF]

open access: yes, 2017
The Middle Pleistocene glacial history of northern East Anglia is a controversial topic with differing opinions surrounding chronology, provenance and the relative stratigraphic framework.

Ice-crevasse sedimentation in the eastern part of the Głubczyce Plateau (S Poland) during the final stage of the Drenthian Glaciation

open access: yesOpen Geosciences, 2020
Glacial sediments in the eastern part of the Głubczyce Plateau, at the Krowiarki site, were studied. Two units were distinguished within the sedimentary succession.

Diamicton facies in the vicinity of Duhlata cave, Bosnek karst region, Southwestern Bulgaria

open access: yesReview of the Bulgarian Geological Society, 2021
Karst caverns in the Upper Triassic dolostones of the Rusinovdel Formation are filled with allochthonous clastics (brecciaconglomerates with maximum boulder size) and locally with speleothems (flowstones). Deposition of the former (diamicton facies) by debris flows resulted from extreme flood events along the upper reaches of Struma river. The polymict
