Particle size distributions within nonsorted stony earth circles, Colorado

Auteur :
BEYER, P.

Description :
This study evaluates 2 models (frost heave and deflation) for the formation of nonsorted stony earth circles in 2 populations of circles on Niwot Ridge, Colorado, by examination of the coarse particle and silt distributions within the circles using principal components, cluster, and discriminant analyses. Data generated in this study do not support the idea that circles within a small region necessarily result from the same process.
