Shear wave studies in Glacial Till

SEG Technical Program Expanded Abstracts 1996, 1996
Abstract Within a high-resolution shallow reflection survey program in Saskatchewan. Canada, S-waves were produced using a single seismo-electric blasting cap and were found to be distinguishable from surface wave phases. The local glacial deposits have average velocities of 450 m/s. V p /V s ratios average 3.6 in these sequences, but

Azimuthal Resistivity To Characterize Fractures In A Glacial Till

15th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2002
Azimuthal resistivity was used to characterize fractures in a glacial till at the King site, near Birsay SK. The King site is a hydrogeological test site where the presence of fractures has been identified, but the fracture orientation was not previously known.

Observations on the undrained strength of a glacial till

Géotechnique, 1974
The engineering character of stiff glacial tills has not been widely reported. There is increasing frequency of building heavily loaded structures bearing on tills and in the assessment of their foundation design difficulty has been experienced in interpreting the rather scattered results frequently obtained in testing such stony soils.

The Fracture Porosity of Glacial Till

Canadian Journal of Earth Sciences, 1975
The effective porosity of fractured till is obtained using two independent methods. The first method is based on tritium tracer studies, hydraulic head measurements and digital model simulations, while the second method is the mathematical evaluation described by Snow (1968) for fracture porosities of consolidated rock.

The influence of fissures on the consolidation of a glacial till

Geological Society, London, Engineering Geology Special Publications, 1991
Abstract The influence of fissures on the permeability, compressibility and consolidation rate properties of glacial till at three sites in and near Glasgow, Scotland has been studied. This included both the determination of the orientation and other characteristics of the fissures in the tills, both in-situ and in laboratory specimens, and ...

The Glacial Till of Fair Isle, Shetland

Geological Magazine, 1970
SummaryReddish-brown glacial till containing millet seed sand grains occurs on Fair Isle, Shetland. Both the colour and the millet seed grains may have come from Permo-Triassic sandstones on the sea floor in the neighbourhood of Fair Isle, since the Devonian rocks of the area are not often red and do not give rise to till containing millet seed grains.

A Flat Dilatometer to Operate in Glacial Tills

Geotechnical Testing Journal, 2001
Abstract The Marchetti flat dilatometer is a simple to operate in-situ testing device that was designed for use in clays, silts, and sands. A new dilatometer has been developed for use in a greater variety of soil types, in particular glacial tills.
