Abstract

Bedrock surfaces in the Ouachita Mountains, Arkansas, exposed by spillway construction and which had not been previously subjected to surface weathering environments, developed 15-20 cm thick soil covers in less than 3 decades. The results suggest that initial chemical weathering within newly-exposed rock fractures in resistant sandstone strata and chemical weathering of weak shale layers, coupled with accumulation of organic and mineral debris in fractures and microtopographic depressions facilitates plant establishment, wich accelerates local weathering rates
