[SCG16-13] Carbon in lunar mantle
Keywords:Earth, Moon, mantle, carbon, Remote sensing, Kaguya
Another evidence of volatile inside moon is pyroclastic glass in Apollo samples. Volatile-induced pressure is required to produce them even under low gravity and no atmosphere on the Moon. The global survey by spectral profiler (SP) onboard Kaguya has discovered that Sinus Aestuum is the largest pyroclastic deposit on the Moon (Yamamoto et al. 2014) . From the spatial extent and thickness, we deduce the total amount of volatile gas which have rapidly brought the parent magma to the surface. Assuming that the gas consists of only CO, we will estimate the carbon content in the lunar mantle.
