Highly silicic compositions on the Moon.

摘要: Using data from the Diviner Lunar Radiometer Experiment, we show that four regions of Moon previously described as "red spots" exhibit mid-infrared spectra best explained by quartz, silica-rich glass, or alkali feldspar. These lithologies are consistent with evolved rocks similar to lunar granites in Apollo samples. The spectral character these spots is distinct surrounding mare and highlands material composed pure plagioclase variety landforms associated silicic suggests both extrusive intrusive magmatism occurred on Moon. Basaltic underplating preferred mechanism for magma generation, leading formation landforms. This silicate liquid immiscibility could lead bodies.
