This heavily modifies its physical properties, chemical compositions and mineralogical features, and in turn, the optical reflectance spectra of the moon, said the paper.
The original perovskite, calcium titanium oxide, is a mineral discovered in the Ural mountains in 1839 and named after Count Lev Perovski, a Russian mineralogist.
Chandrayaan-1 (carrying a NASA Moon Minerology Mapper) found the first definitive spectroscopic signatures of water ice in dozens of craters congregated around the Moon's poles.
Chandrayaan-1(携带 NASA 月球矿物学绘图仪)在月球两极周围聚集的数十个陨石坑中首次发现了水冰的明确光谱特征。
Specimens of everything known in mineralogy lay there in their places in perfect order, and correctly named, divided into inflammable, metallic, and lithoid minerals.
The original perovskite was a mineral discovered in the Ural mountains, in Russia, in 1839, and named after Count Lev Perovski, a mineralogist from that country.
By this time his interests had developed beyond minerology into the harder sciences, particularly chemistry, but it was eventually physics which would prove his calling in years to come.
Assumed metallurgical recoveries and payabilities for all metals and discussion of the basis on which the assumed recoveries and payabilities are derived (metallurgical test work, detailed mineralogy, similar deposits, etc.).
He was professor at the Johannaeum, and was delivering a series of lectures on mineralogy, in the course of every one of which he broke into a passion once or twice at least.
I freely confess that I was exceedingly fond of geology and all its kindred sciences; the blood of a mineralogist was in my veins, and in the midst of my specimens I was always happy.
" I was always fond of mineralogy you remember, and I've been tapping round a good deal lately, so I've learned to know precious metals when I see them, " Mac said with his shrewd smile.
