Meteorite hunter : ウィキペディア英語版 | Meteorite hunter
A meteorite hunter is a person engaged in the search for meteorites. Meteorite hunters may be amateurs who search on the weekends and after work, or professionals who recover meteorites for a living. Both frequently use tools such as metal detectors or magnets to discover the meteorites. == Searching ==
If the meteorite is of the iron or stony iron variety a magnet (usually mounted at the end of a stick) will pick it up from the soil surface or a metal detector will often detect it through many inches of soil. Stony meteorites —which make up the large majority of meteorites that fall— may not have a high enough nickel iron content to set off a metal detector. Large and very sensitive metal detectors may be used as well as ground-penetrating radar, lidar, and even landmine detectors.〔(Rare meteorite found in Kansas field ), MSNBC, October 16, 2006.〕 Although meteorites fall uniformly across the globe they do not typically remain on the surface in areas with a large amount of yearly rainfall. If a newly fallen meteorite is not recovered within a few months it is likely to be buried with alluvium or covered by plant growth. Some arctic and desert regions have proven to be well-suited to preserving meteorites, and can provide excellent surfaces for hunting visually.
