WebThe lithosphere consists of the crust and the upper mantle. As we read before, crust can be divided into two different types, continental and oceanic crust. Both types “float” on the denser mantle. Continental crust is about 25-90 km (15-55 mi) thick and divided into tectonic plates. These plates move slowly (just a few WebMineralogical-chemical differences suggest a higher FAN component in the rim and that this represents FANs excavated from the deep lunar crust.

How is the difference in crust and mantle composition explained?

WebMineralogical-chemical differences suggest a higher FAN component in the rim and that this represents FANs excavated from the deep lunar crust. If it exists, the Mg-rich olivine previously identified within the Crisium rim is most likely related to deep, complementary versions of the Mg-suite rocks from L-20. WebThe portion of the interior beyond the crust is called the mantle. It is in a solid-state. It has a density higher than the crust portion. The thickness ranges from 10-200 km. The mantle extends from Moho’s discontinuity to a depth of 2,900 km. The asthenosphere is the upper portion of Mantle.
