Description

Using the Multiband Imager on the [/Kaguya Kaguya] orbiter, mission scientists deduced the anorthosite content of 69 craters, finding that all large fresh craters have nearly pure anorthosite, supporting the proposal of a global magma ocean. 
 
 

Additional Information

Table 1 includes anorthosite abundance and optical maturity index for 69 mostly fresh craters.
A = >98% anorthosite (pure)
B = 90-98% anorthosite
C = <90% anorthosite

Optical maturity index values > 0.6 mean the crater is fresh. Note that Copernicus is not fresh enough to be considered fresh.
