The coalfields of southwest Virginia lie in the Appala- chian Plateau physiographic province.The area is charac- terized by a deeply dissected,mature topography of V- shaped valleys with steep slopes and narrow ridges.The landforms were shaped by the erosion of a high plateau of sedimentary origin.These sedimentary rocks,which range from Cambrian through Pennsylvanian in age,were uplifted as a block,with minimal deformation compared to the Valley and Ridge physiographic province.Accord- ingly,geologic strata remain nearly level to gently slop- ing,except near the edge of the eastern thrust block that marks the beginning of the Valley and Ridge province.In northern Dickenson County near the Buchanan Coun- ty border,the Russell Fork fault bisects the Virginia coal- fields (Fig.1).
