Cratonic basins are mysterious features of the interior of continents. A saucer-shaped feature filled with sedimentary rock is formed but the mechanism of subsidence is unknown. These basins have collected thousands of metres of sediments that in most cases have received little deformation until uplift. Moreover, these basins commonly have thinned crust and an uplifted mantle underneath, and the said crust has relatively high density. Such features are amazingly similar to what is expected after impacts. A brief description of the Belt, Williston, Illinois, Michigan, and Hudson Bay Basins of North America shows that these basins fit an impact origin. Two other amazing basins from other continents, the South Caspian and Congo Basins, also described, can readily be explained by large impacts.To finish reading this technical article from the Journal of Creation, click on "Large cratonic basins likely of impact origin".
