Structures caused by repeated freezing and thawing in various loamy sediments: A comparison of active, fossil and experimental data
Abstract In this paper, the authors present the results of both macroscopic and microscopic investigations on structure development created by repeated ice lensing in various loamy experiments. Experimental data are compared with observations performed on active forms in High Arctic and Alpine Mount...
