Abundance and Distribution of Iron on the Moon
The abundance and distribution of iron on the moon is derived from a near-global data set from Clementine. The determined iron content of the lunar highlands crust (∼3 percent iron by weight) supports the hypothesis that much of the lunar crust was derived from a magma ocean. The iron content of low...

The abundance and distribution of iron on the moon is derived from a near-global data set from Clementine.
