Has many known isotopes, with mass numbers range from 21 to 42; however, only Al (stable) and Al (radioactive, t1⁄2 = 7.2×105 years) occur naturally. Al has a natural abundance above 99.9%. Al is produced from argon in the atmosphere by spallation caused by cosmic-ray protons. Isotopes are useful in dating marine sediments, manganese nodules, glacial ice, quartz in rock exposures, and meteorites. The ratio of Al to Be has been used to study transport, deposition, sediment storage, burial times, and erosion on 10 to 10 year time scales. Cosmogenic Al was first applied in studies of the Moon and meteorites. Meteoroid fragments, after departure from their parent bodies, are exposed to intense cosmic-ray bombardment during their travel through space, causing substantial Al production. After falling to Earth, atmospheric shielding drastically reduces Al production, and its decay can then be used to determine the meteorite’s terrestrial age. Meteorite research has also shown that Al was relatively abundant at the time of formation of our planetary system. Most meteorite scientists believe that the energy released by the decay of Al was responsible for the melting and differentiation of some asteroids after their formation 4.55 billion years ago.
Because of its strong affinity for oxygen, is almost never found in the elemental state; instead it is found in oxides or silicates. Feldspars, the most common group of minerals in the Earth’s crust, are aluminosilicates. Native metal can only be found as a minor phase in low oxygen fugacity environments, such as the interiors of certain volcanoes. Native has been reported in cold seeps in the northeastern continental slope of the South China Sea. Chen et al. (2011) propose the theory that these deposits resulted from bacterial reduction of tetrahydroxoaluminate Al(OH)
