Using GIS to Evaluate an Enigmatic Diamicton in the Spring Mountains, Southern Nevada

Professional Geographer, 2003
Abstract The Spring Mountains are located in southern Nevada and lie along the western margin of the Las Vegas Valley. A diamicton located approximately 2,590 m (8,500 ft) above sea level in the Spring Mountains contains numerous striated limestone clasts ranging in size from 0.5 cm to 1.0 m.

Pebble Fabric in an Ice-Rafted Diamicton

The Journal of Geology, 1985
Pebble fabric studies on ice-rafted diamictons have been limited to general observations, with authors noting preferences toward vertical, random, or horizontal orientations. To clarify such observations, pebble fabric data were collected from a fossiliferous diamicton of late Pleistocene age located on Whidbey Island, Washington. The ice-rafted origin

Microstructures in diamictons—evidence of subglacial bed conditions

Geomorphology, 1992
Abstract Examination of microstructures within diamictons from southern Ontario, Canada, and southern Bavaria, and Baden-Wurttemburg, Germany reveal evidence illustrative of certain subglacial bed conditions. The microstructures from Ontario were obtained from a complex glacial melange unit that forms the internal structure of an isolated drumlin ...

Sedimentology and depositional environments of the Lund Diamicton, southern Sweden

Boreas, 1990
The Lund Diamicton (earlier named Lund Till) in SW Skåne, S. Sweden, is a glacioaquatic sediment consisting of clay and massive and laminated diamictons. It is characterized by clasts derived from the Baltic depression and its depositional history can be summarized as follows: After deglaciation, large fields of stagnant ice remained in the area and a ...

Origin of diamictons on the Barents Sea shelf

Lithology and Mineral Resources, 2009
Occurrence conditions and lithological-paleontological characteristics of two diamicton units developed in the southeastern segment of the Barents Sea shelf are considered. It is shown that they are lithologically analogous to the present-day (undoubtedly aqueous) diamicton mud.

Problems associated with seismic facies analysis of diamicton-dominated, shelf glacigenic sequences

Geo-Marine Letters, 1990
Diamicton-dominated shelf glacigenic sequences are characterized on high-resolution seismic records by a structureless to chaotic acoustic texture, often with abundant hyperbolic (point-source) reflections. Existing depositional models, based primarily on seismic data, have been constructed on the basis that this acoustic signature is indicative of ...
