Description
Using the Multiband Imager on the 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.
