Where is shale formed.

Environmental characteristics include the nature and distribution of inorganic contaminants, such as metals and metalloids like arsenic, iron, and lead, in clay-bearing rocks. These environmental factors have the potential to affect the use of clays in natural and industrial applications. --NORA K. FOLEY.Detritus sedimentary rocks are formed when rock fragments, debris or sediments accumulate over time and can be either organic or inorganic in makeup. These detrital rocks come together under great pressure, usually over many years. The debris, or matter that form the rocks, can be either organic or inorganic. A chunk of coal.The Green River formation, an oil-shale formation in Colorado, Utah, and Wyoming, is a potentially valuable source of synthetic crude oil. In eastern Germany and Poland the Kupferschiefer , a bituminous shale , is mined for copper, lead, and zinc. The Burgess Shale is found in an area of the Canadian Rocky Mountains known as the Burgess Pass, and is located in British Columbia's Yoho National Park. Part of the ancient landmass called Laurentia, centered in Hudson Bay, the Burgess Shale represents one of the most diverse and well-preserved fossil localities in the world.

The shale formation may be inclined or declined from a single point, or it may be thicker or thinner. It is possible for the shale formation to be discontinuous if there was an isolated geologic uplift.) Why does the natural gas output of a well decline over time?
