The astron type of graben ('astrobleme' + 'craton') formed by high-energy impact on the planet's (or moon's) surface is defined, cratering experiments with explosives and coring of debris and subjacent impacted layers are scrutinized, and a search for eroded astrons on the earth comparable with ancient lunar cratering is announced. Earth arcuate features possibly representative of primary astrons or of astron grabens reactivated by plate tectonics are examined: the West African circular bulge, China coast, Himalayas, Gulf of Mexico, Aleutian archipelago, or Great Australian Bight. Attention is directed to the transform faults of the Pacific floor, apparently radiating from the world's largest positive gravity anomaly NE of Australia, and reminiscent of lunar maria mascons (mass concentrations). Possible effects of such post-Cambrian high-energy impacts on the biosphere (with sequelae detectable in discontinuities in evolution of life forms over a wide area, and drastic modifications of paleogeomagnetism and climate), and use of the phenomenon in global prospecting, are mentioned.
