Meteorite Impacts, Craters and Multi-ring Basins
One of the principal new results of space exploration has been the demonstration that impact cratering was endemic throughout the solar system. Whether one is contemplating the cratered face of Mercury, the traces of the bombardment surviving on Venus or the Earth, the heavily cratered highland surface of the Moon or the southern hemisphere of Mars, the battered potato-like surfaces of Phobos a...
متن کاملThe formation, morphology, and economic potential of meteorite impact craters
One quarter of the known terrestrial impact craters are associated with economic deposits of some kind whether they are mineral ores, hydrocarbons or even evaporite minerals and fresh water. Detection of new structures is hindered by the apparent randomness of impact, terrestrial erosional processes, non-systematic search efforts, and that 30% of craters are buried. The vast expanse of the Eart...
متن کاملThe Search for Possible Source Craters for Martian Meteorite Alh84001
ALH84001 is the only martian meteorite currently known with a crystallization age of 4.5 Ga. This ancient age indicates the meteorite must come from the ancient crust of Mars, located primarily in the southern hemisphere of the planet. The 4.56 Ga crystallization age, the 16 Ma ejection, and theoretical models of how material is ejected off Mars were used to identify possible source craters for...
متن کاملMonazite Dating of Lunar Meteorite Nwa
Introduction. According to their textural and geochemical similarity it was suggested previously that the lunar meteorite NWA 4734 could be launch paired with Antarctic Mare basalts (LAP 02205/224/226/436-03632-04841) themselves possibly paired with NWA 032/470 lunar meteorites despite their different textures (1-5). A possible clue about the pairing issue is evidently their age. Method : After...
متن کاملAfrican meteorite impact craters: characteristics and geological importance
Abslzact Geologists have realized that impact cratering is the single most important surface-forming and modifying process for the other terrestrial planets and the satellites of all planets. The recognition of impact cratering as an important geological process on earth has been rather slow. However, geologists are now realizing that giant impacts have had a determining influence on the geolog...
