Processes dominating macro-fabric generation in periglacial colluvium

Description :
This study uses two-dimensional macro-fabric analysis as a recorder of the dominant mode of mass-wasting on a slope. Clast trend and plunge data were collected from 68 sites at Eagle Summit, Alaska, and examined in two separate dimensions : the plane of the slope to represent the sress-field driven by gravity; and in a vertical plane trending down the slope to represent the stress-field created by frost heaving pressures. The results presented here suggest that slope angle plays an important role in determining the relative importance of frost heave versus gelifluction.
