Laboratory Modeling of Meteorite Impact Craters by Z-pinch Plasma
Desai, et al. [1] simulated microparticle lunar impact craters using laser impacts. They produced crater diameters of several hundred μm in Al. Ford [2] made observations about lunar craters simulated by spark-machining on metal. These were also very small scale craters. This work expands the size of simulated impact craters from their sub-millimeter craters to craters over a centimeter and exp...
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 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...
متن کاملZ-pinch Discharge in Laser Produced Plasma
Z-pinch effects in a laser produced aluminium plasma were investigated with a relatively low current fast coaxial electrical discharge. The ion flux in the laser produced plasma (LPP) was monitored with a Langmuir ion probe and the line density was controlled by using an aperture to select the portion of the LPP which enters the discharge cell. The Zpinch dynamics were recorded using time-resol...
متن کاملMeteorite 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...
