This is a list of possible impact structures on than features on Earth include candidate impact sites that have appeared several times in the literature and/or have been endorsed by the Impact Field Studies Group (IFSG) and/or Expert Database on Earth Impact Structures (EDEIS),. The Earth Impact Database (EID) is used at Wikipedia as authoritative .   Incredible Meteorite Found With Hieroglyphics Canada - This story was published by TW Patterson at the Conwichan Valley Citizen on Jan, The Cowichan Valley is a region around the Cowichan River and Cowichan Lake on Vancouver Island, in British Columbia, Canada.

The St. Robert meteorite has been typed as an H5 chondrite and the first stony meteorite to be found in Quebec. Studies of the fall indicate the total fall mass of meteorites larger than 55 g to be between 65 kg to kg distributed through to fragments.   M eteoric impact craters are among the most interesting geological structures on our planet. While most of these craters have been eroded away by natural processes over the vast expanse of geological time, many of these ‘astroblemes’ (literally meaning star wound in Greek) still remain in the form of a circular geological scar of crushed and deformed bedrock.

Export of Canadian Meteorites Reporting of a meteorite found in Canada is not mandatory. Meteorites found in Canada can be sold in Canada. The. export Under the Cultural Property Export and Import Act (S.C. , c), which came into force September 6, a Canadian find cannot be exported without a permit from the.

Glass from the West Clearwater Lake hypervelocity impact crater contains numerous spheroids, 10 to μm across, which appear to have formed at high temperatures as fluids immiscible in the enclosing melt. The spheroids are distinguished from small, normal, largely void gas vesicles, which are also present, by being completely filled in all cases; by having Cited by: Clearwater Lakes, Quebec, Canada.

Twin impact craters, which are formed simultaneously by two separate, but probably related, meteorite impacts, are very rarely recognized on Earth. This pair is situated in crystalline bedrocks of the Canadian Shield. Hische, R., Clearwater impact structure, Quebec, Canada, II: Modelling of the impact conditions (abstract).

Init was suggested that the Clearwater lakes were of an impact origin (Beals et al., ).
