The moon has been hit by a bunchaton of impactors(asteroids n stuff)
of which are divided into three classes.
Type C - Carboniferous (water and organics)
Type M -metal (iron and such)
Type SS - $$ (platinum group metal)
Now consider a raisin cake.

It's lying about what's in the raisins.
Some digging might be required.
Note: my default setting is snark...can't help it. Birth defect I think.
No offense intended.
