Middle Pleistocene Till Lithostratigraphy in South Bedfordshire and the Hitchin Gap [PDF]

open access: yes, 2009
A revised lithostratigraphy and glacial history of north Hertfordshire and south Bedfordshire is based upon detailed textural data in the clay to fine gravel fraction, carbonate content, small clast lithological data and macrofabrics, derived from ...

Grain-size distribution and origins of unconsolidated fine sediments in ice-free areas, Soya Coast, East Dronning Maud Land, East Antarctica

open access: yesAntarctic Record, 2005
Unconsolidated fine sediments (UFS), sporadically deposited in Soya Coast ice-free areas, have often been described as glacial deposits (till) or subglacial till in previous studies, but their genesis and depositional environments have never been ...

Automated X‐ray computed tomography‐based analysis of clast fabric in drill‐cores of glacial diamicts using deep learning models

open access: yesBoreas
Clast‐fabric analysis is a widely used method for investigating depositional and deformation processes in glacial sediments. However, traditional field‐based approaches lack standardization, are time consuming and introduce sampling bias.

Mechanical properties of soils in internal waste bank of lignite mines and their primary characteristics [PDF]

open access: yesArchives of Civil Engineering
The modern development of urban areas is related to, among others, the location of industrial facilities on the outskirts of cities. More and more often, commercial buildings are founded on areas that have not been used for construction so far.

Two-dimensional apparent microfabric of the basal Late Weichselian till and associated shear zone: case study from western Latvia [PDF]

open access: yesEstonian Journal of Earth Sciences, 2008
The examination of glacial sediments in thin sections has become a common procedure in recent years. Apparent sand grain orientation (microfabric) in thin sections is one of the key elements marking certain microstructures.

Exploring the use of zircon geochronology as an indicator of Laurentide Ice Sheet till provenance, Indiana, USA [PDF]

open access: yes, 2017
A pilot study was designed to evaluate the potential of zircon geochronology as a provenance indicator of till from the Lake Michigan, Saginaw, and Huron-Erie Lobes of the Laurentide Ice Sheet. Based on existing ice flow-path models, we hypothesized that

Soil Development in Quaternary Glacial Deposits, Waterton Park Area, Southwestern Alberta [PDF]

open access: yes, 1988
Pedological investigations in the Waterton Park area provide a useful means of testing subdivisions of Quaternary glacial deposits based on geomorphic relations. Soils in the region, however, including Podzols, Brunisols, Luvisols, and Chernozemics, also

Marine record of late quaternary glacial-interglacial fluctuations in the Ross Sea and evidence for rapid, episodic sea level change due to marine ice sheet collapse [PDF]

open access: yes
Some of the questions to be addressed by SeaRISE include: (1) what was the configuration of the West Antarctic ice sheet during the last glacial maximum; (2) What is its configuration during a glacial minimum; and (3) has it, or any marine ice sheet ...
