of several proven impact craters (e.g., Steen River, Bow Island, Eagle Bute, Whitecourt) where shock metamorphic effects were found and other inferred astroblemes (e.g., James River, Manyberries). Impact craters are either 'simple' or 'complex' structures that may be associated with production of hydrocarbons. Simple craters are bowl-shaped depressions with a structurally uplifted rim area, which is overlain by ejecta with discernible reversed stratigraphy, at least close to the rim. Complex craters are larger and are characterized by a complex and downfaulted rim area, a relatively flat annular floor surrounding uplifted target rocks in the form of a topographic peak or ring or both, depending on size. At even larger diameters, impact craters may form impact basins, which are characterized by (multiple) interior rings. Hydrocarbons production at impact structures occurs from structural traps in the rim and central uplift and from brecciated target rocks, including crystalline rocks. The crater form is usually altered by erosion and sedimentation processes and, at longer time-scale, tectonism.</SPAN></SPAN></P></DIV></DIV></DIV> A compilation of several proven impact craters where shock metamorphic effects were found and other inferred astroblemes.
