Multiple bullets containing a tiny spectrometer could be shot into the lunar soil by an astronaut or rover, allowing analysis ...

The widespread natural occurrence of two-pyroxene assemblages and the temperature effect produced by the component redistribution between the constituent minerals have long been used to obtain ...

But one problem with that idea is that the South Pole–Aitken basin seems to be dominated by a mineral called pyroxene, which doesn’t quite fit Pragyan’s data, says Anand. Resolving this will ...

The moon was once engulfed by a massive magma ocean, analysis of geological samples collected by India's Chandrayaan-3 ...

Other samples have contained more pyroxene than olivine; the samples taken by Pragyan, however, had more olivine than pyroxene. As the paper notes, “This a new finding and is at odds with other ...

Compared to the pristine mantle, there is a lot less of the mineral pyroxene in the rocks. They also have very high concentrations of magnesium. Both of these result from a high degree of melting.

This forms when the mantle partially melts. The results surprised them. “There is a lot less pyroxene in the rocks, and the ...

As the magma ocean cooled, denser minerals such as olivine and pyroxene sank to form a deeper layer called the mantle, while the ferroan anorthosite – being less dense than the surrounding magma ...

Earlier researches indicated that small amounts of water are contained in a variety of lunar soil minerals such as glass materials, plagioclase, olivine and pyroxene. Meanwhile, the water content ...

My research has concentrated in several fields in petrology. My major fields of interest include: Geologic evolution of the Wyoming Province: The Wyoming province is one of the oldest Archean ...
