After revealing traces of iron deposits and formation of craters recently, it is now showing pin-point evidence on the evolution of the Moon. This implies that the rocks of the Maria and Highlands cooled at different rates from the molten state and so were formed under different conditions. The lunar highlands were formed about 4.5 billion years ago, they are the oldest features (or regions) on the moon.
Chandrayaan proves lunar highlands were formed by magma. The rocky remains that floated to the top appear to have transformed into the Moon's highlands or mountains,” an Isro scientist explained. “The hot liquid, magma, seems to have flowed on to the surface and taken the form of lava.
From the highlands to the plains, the European Space Agency’s SMART-1 probe is giving scientists an up-close view of the dark and light areas on the …
Chandrayaan proves lunar highlands were formed by magma Chandrayaan-1 is certainly making strides in the time it has been around the Moon. The lunar highlands were formed about 4.4 to 4.6 billion years ago by flotation of an early, feldspar-rich crust on a magma ocean that covered the Moon to a depth of many tens of kilometers or more. The Highlands rocks are largely Anorthosite, which is a kind of igneous rock that forms when lava cools more slowly than in the case of basalts.
