| Abstract: | Geologic marks related to extraterrestrial impact events, such as im pact split gravels, impact brecciate layers, impact dikes, microirghizites, micr otektites, especially meteoritic residues, were discovered on the boundary betwe en Sinian/Cambrian in Tianmenshan of Western Hunan, which may possibly demonstra te that an extraterrestrial impact event has ever occurred there on the SC bound ary. |
