Topic: Solifluction


  
  AW2004 Abstract: Kinnard
In the spring of 2002, surface movement was monitored on five solifluction lobes using repetitive surveying of surface targets, while groundwater levels and thaw depths were measured on these lobes and along the entire slope.
Spatial analysis of lobe dispersion suggest that the population of solifluction lobes represents an organized succession of wave-like benches, whose wavelength and amplitude are controlled by the downslope increase in solifluction activity.
Excavation of a solifluction lobe to uncover the buried humus horizon.

Solifluction lobes can be seen drooping downhill near many of the roads in the Interior, including the Steese and Taylor highways.
Solifluction is a combined flow and slip movement, involving the surface layers in areas of permafrost.
Solifluction can occur on even moderate slopes, because of the ease with which a lobe slides on the frozen substratum.

Like loose folds of mossy skin hanging down the flanks of sleeping giants, solifluction flows can be seen on the sides of hills of interior Alaska.
Solifluction is a slow downward flow of water-saturated soil.
In contrast to unitary flow in solifluction, soil creep moves the soil particles individually and thereby tends to mix them up as the creep proceeds.

 The Geobotanical Atlas: Regional Description, Glacial Geology
Solifluction is most widespread during spring and early summer, when the active layer generally is saturated with moisture that is released by thawing but remains confined above the surface of impermeable permafrost.
Solifluction has redistributed much of the loess cover from upper to lower parts of moraine flanks, and ubiquitous horsetail drainages and a lack of stream channels indicates that solifluction probably is still active.
For example, solifluction continued to be at least intermittently active on slopes, and silty, ice-rich sediments continued to accumulate in swales and along the courses of sluggish small streams.

 The hunt for Solifluction Placers - common in cold regions?   (Site not responding. Last check: 2007-10-14)
The solifluction placers are confused with fluvial placers due to both types being prevalent on valley floors.
The solifluction placers tend to have blurred contacts with the underlying bedrock and - in the Sergelen Goldfield - are the only, or dominant, sediment on almost all valley floors.
Solifluction placers are dominant in the Forest-Steppe Transition Zone and the Steppe Zone where extremely cold winters and semi-arid conditions favour solifluction and suppress surface water flow.

 Solifluction   (Site not responding. Last check: 2007-10-14)
Solifluction is a special type of creep that occurs in areas of permafrost.
During cryoturbation, "small ridges and mounds of bare soil are produced by the processes of frost churning (cryoturbation) and soil flow (solifluction).
Freeze-thaw generates a circular motion in the surface material, heaving the soil to the surface (the light- coloured areas) and dragging it down at the margins to form gutters (the darker, vegetated areas).

 Solifluction Cairngorm
A contemporary solifluction slope in Siberia, showing lobes and terraces and the gradual displacement of material downslope towards the river.
As delicate features such as tors have survived beneath ice covers, it is possible that the larger solifluction terraces and lobes may be of considerable age.
Although solifluction deposits are not an obvious feature on the Cairngorm Granite, considerable thicknesses of frost-shattered and soliflucted debris occur on Dalradian metamorphic rocks in the Ladder Hills.

Solifluction is a type of mass wasting that is restricted by climate to high latitudes.
As you are very unlikely to ever see this in your lifetime, it is included here as more of a curiousity than a topic for detailed study.

But as pertaining to questions i must answer from class, the general idea behind this project is to see if solifluction occurs on mars in a small scale.
For example if solifluction occurs at a proposed building site...the building would collapse in only a couple years.
For this project it is just as important if there is no solifluction then if it is present because then we definately know what is not there.

Solifluction or Solifluxion is an errosion process that occurs in areas with a perma-frost.
During the winter the whole thickness of the soil is frozen.
The gentle flow of the material will tend to align rocks to the direction of flow.

This is based on a general statement that the downslope component of solifluction causes elongated clasts to become oriented in the direction of the slope.
Fabric data were collected in areas of active solifluction at Eagle Summit, Alaska, and Niwot Ridge in the Colorado Rockies.
The results from Eagle Summit indicated that, contrary to previously reported solifluction fabrics, a high degree of variability was evident across a meso-scale slope.

 Welcome to Adobe GoLive 5
The latter approach had never been tried, but because the soil profile became incorporated into the permafrost as it was buried by the erosional process of solifluction, we were hopeful that this would preclude ‘contamination’ of the ancient seed bank with recent seeds.
Earthwatch volunteers in Alaska ranged in age from 16 – 76, and were crucial to the discovery of ancient viable seeds in the arctic tundra.
Although we examined the seeds buried by solifluction, it is reasonable to assume that such long-term dormancy exists in permafrost not buried by solifluction as well.

 Solifluction
Solifluction is a type of earth flow found in periglacial environments underlain by permafrost.
During the summer the surface layer of permafrost melts creating a water-saturated layer that becomes mobile.

Solifluction steps and risers, Lee Ridge, Glacier National Park
Abstract: Solifluction patterns on Lee Ridge, Glacier National Park, Montana, USA, were characterized through a combination of field transects, enhanced, digital aircraft data, and geostatistics.
The objectives were to (i) assess the role of high spatial resolution digital imagery for mapping the areal extent and spatial pattern of solifluction steps and risers through digital enhancements [i.e., principal components analysis (PCA) and wavelet transforms (WTFs)] of ADAR-5500 aircraft imagery; (ii)...

 mass wasting study questions   (Site not responding. Last check: 2007-10-14)
According to the ternary diagram illustrating mass wasting mechanisms and their products (on page 2 of the Mass Wasting web pages), which of the mass wasting products may consist of approximately 50% flow and 50% heave?
On the ternary diagram, a mass movement that is 50% flow and 50% heave would be located on the edge of the diagram, half way between the flow apex and the heave apex.
By far the mass movement that involves the lowest initial slope (ignoring ground subsidence, which is not among the choices) is soil creep.

The study regions have a cold continental climate that is favorable for the development of continuous permafrost in the upper altitudes, and discontinuous permafrost in the lower altitudes which are exposed to the south.
The Mongolian mountain areas near the southern boundary of permafrost are shaped by cryogenic processes, forming cryoplanation terraces, active solifluction valleys, cryopediments and solifluction cirques.
