water exploitation, mining, and quarrying (Drew, ) (fi g. 2). Minerals associated with karst have been exploited for many years. Some car-bonate rocks contain valuable supplies of water, oil, and gas, may weather to form bauxite deposits, and are associated with manganese and phosphate rock (guano). Coal is often found within thick carbon-Environmental characteristics include the nature and distribution of inorganic contaminants, such as metals and metalloids like arsenic, iron, and lead, in clay-bearing rocks.

Hence they provide a lateral support to vertical slopes of soil that would otherwise collapse into a more natural shape. Most common materials used for retaining walls are:The country rock is micaceous sandstone with thin layers 1 to 2 inches of bluish slate. The eastern wall is sandstone, and western wall slate, dipping both east and west. The lower levels of the mine contain graphitic shale with pyrite cubes.
