| Abstract: | Systematic Catastrophic Consequences triggered or caused by giant impacts of extraterrestrial bodies are summarized in this paper, including various geologic processes, palaeoclimatic fluctuations, mass extinctions and palaeogeomagnetic reversals. It's also pointed out that comprehensive and thorough studies on the catastrophic effects are of great importance for better understanding of the Earth's evolution and development. |
