Characteristics and evolution process of the ridge-groove sequence of the Jiulongtan glacial accumulation in Mengshan, Shandong: with the discussion on the difference of accumulation sequence of glacier and debris flow

open access: yesDizhi lixue xuebao, 2021
The existence of Quaternary glaciers in the medium-low mountainous areas in the east of China has been disputed for a century. As an important evidence for glacial accumulation in the east, "mud-gravel" (moraine) has long been referred to as debris flow ...

The development of a late Weichselian - early Holocene subaqueous ice-contact fan, Teikangas, SW Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1996
The depositional environment of the Teikangas formation in southwestern Finland has been studied. The formation is an isolated, ice marginal accumulation of coarse-grained sediments north of the Hämeenkangas ridge, related to the Weichselian ice sheet ...

Soil formation in high elevation and permafrost areas in the Qinghai Plateau (China) Edafogénesis en zonas elevadas y con permafrost en el Plateau Qunghai (China) Formação do solo em áreas de elevada altitude e em ambientes"permafrost" do planalto de Qinghai Plateau (China) [PDF]

open access: yesSpanish Journal of Soil Science, 2012
<p style="text-align: justify;">Soil systems continuously gain and lose matter and energy even in areas where climate is too harsh to support the higher plants such as in high elevations and in permafrost environments. The purpose of this

Extent and dynamics of the Saalian ice-sheet margin in Neple, eastern Poland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2018
The Neple site is located on a marginal moraine between the valleys of Bug and Krzna rivers in the southern part of the Polish–Belarusian border area. A glacial diamicton is overlain there by glaciofluvial sand and gravel.

Sedimentary environments in the south-western Barents Sea during the last deglaciation and the Holocene: a case study outside the Ingøydjupet trough [PDF]

open access: yesPolar Research, 2016
A lithological and foraminiferal study of newly acquired sediment cores outside the Ingøydjupet (Ingøy Deep) trough has been carried out to improve constraints on the last deglacial history in the south-western Barents Sea.

Little Ice Age glacial geomorphology and sedimentology of Portage Glacier, South-Central Alaska [PDF]

open access: yesFinisterra - Revista Portuguesa de Geografia, 2009
The study of glacial landforms and deposits is important, as it isdifficult to observe processes under modern glaciers and ice-sheets. Thus landscapes and sediments that are the product of present glaciation can give insight into processes that occurred ...

Permafrost-derived dissolved organic matter composition varies across permafrost end-members in the western Canadian Arctic

open access: yesEnvironmental Research Letters, 2021
Organic matter, upon dissolution into the aqueous state as dissolved organic matter (DOM), can undergo mineralization by microbes. There has been increasing effort to characterize DOM released from thawing permafrost because it may perpetuate a ...
