Abstract

Aeolian erosion is known as the process of desert areas. However, it sometimes can be observed in the rural environment, which is open directly to wind affects such as open-mine quarries or weak and soft rock formation areas. In desert regions, particles suspended in the air erode rock surface and cause cavity and drift canals. Rarely, surface erosion due to wind force without suspended particles may be occurred on the rock faces by only wind force without suspended particles. That event is observed in weak and soft rock formations. In this study, the wind effects on the soft rock samples were investigated with using a new designed wind tunnel in the laboratory. Three soft rock types such as ignimbrite, mudstone and fossiliferous limestone obtained from quarries were used in wind erosion tests. Throughout six months, rock core samples had been exposed wind effects under constant air temperature, and month intervals, and weight changes of the samples were measured. The maximum weight loss was measured on mudstone samples with the lowest compressive strength and the highest apparent porosity values.
