Famennian glaciation in the eastern side of Parnaíba Basin, Brazil: evidence of advance and retreat of glacier in Cabeças Formation

Brazilian Journal of Geology
Glaciotectonic features studied in the siliciclastic deposits of Cabeças Formation, Upper Devonian, represent the first evidence of Famennian glaciation in Southeastern Parnaíba Basin, Brazil. Outcrop-based stratigraphic and facies analyses combined with

Neoglacial readvance of the East Antarctic Ice Sheet to the northern Drygalski Basin (western Ross Sea)

Geoscience Letters
Our study investigates late Holocene ice-sheet activity in the northern Drygalski Basin (western Ross Sea) using a multi-proxy approach, including sediment properties, geochemical indicators, and diatom assemblages, combined with AMS 14C ages of a ...

The “Lund Moraine”–the geomorphic limit of the last Young Baltic ice advance in the Öresund region

, 2023
Here we present geomorphological evidence of a previously unrecognised ∼50 km long, ice-marginal moraine complex in southwestern Skåne, southernmost Sweden, which we name the “Lund Moraine”.

Massive ice of the Tuktoyaktuk area, western Arctic coast, Canada

, 1992
The extensive coastal exposure of massive underground ice at Peninsula Point, southwest of Tuktoyaktuk, Northwest Territories, is believed to be intrasedimental ice.

Sedimentology of placer gravels near Mt. Nansen, Central Yukon Territory

, 1993
Bibliography: p. 172-180.Unconsolidated sediments in the Mount Nansen area can be subdivided into eight elastic facies: I) clay-rich diamicton; 2) massive/stratified silt/clay; 3) massive/disorganized pebbly sand/sand; 4) stratified pebbly sand/sand; 5 ...

Evidence for a Middle Pleistocene glaciation of MIS 8 age in the southern North Sea

, 2005
In the cores of borehole 89/2, situated at 54° 00 01′N and 5° 00 04′E about 70 km north of the Frisian Islands in the southern North Sea, two diamictons levels are found at ±70 and 100 m below sea floor (i.e.

Distribution of foraminifera, pre-Pliocene foraminifera and macrofossil debris in sediment core CRP-2 (Table 1)

, 2000
The stratigraphic distribution, assemblage content, paleoecology and age of foraminifera recovered in fourteen of sixteen samples from the 5.63 m thick CRP-2 (Lithostratigraphic Unit 2.2) are discussed.

Stratigraphy and glaciotectonics structures of a relict deforming bed of permafrost at the northwestern margin of the Laurentide ice sheet, Tuktoyaktuk Coastlands, Canada

, 2004
The upper 5-20 m of ice-rich permafrost at three sites overridden by the northwest margin of the Laurentide ice sheet in the Tuktoyaktuk Coastlands, western Arctic Canada, comprise massive ice beneath ice-rich diamicton or sandy silt.

Pre-Late-Wisconsin Glacial History of the Naknek River Valley, Southwestern Alaska [PDF]

, 1996
The lower Naknek River in southwestern Alaska dissects thick (~20m) exposures of Pleistocene glaciogenic sediments. The stratigraphy of the deposits and their physical, geochemical, mineralogical, and geochronological properties were studies to determine

14C ages, grain size distribution and foraminifer abundance of sediments from the Barents Sea shelf

, 2009
The origin of friable sediments blanketing the Barents Sea shelf is considered. It is shown that their characteristic seismoacoustic record patterns reflect low degree of diagenetic transformations and indicates continuous sedimentation.
