sapphirine वाक्य

उदाहरण वाक्य

1. Some assemblages such as sapphirine + quartz indicate very high temperatures.
2. Khmaralite is closely related to sapphirine with a difference in the tetrahedral sequence chain.
3. Other possible minerals formed at dry conditions include sapphirine, spinel, sillimanite, and osumilite.
4. The tetrahedral sequence chain in sapphirine ( Al-Si-Al ) is replaced by the sequence Si-Be-Si in khmaralite.
5. Sapphirine's type locality is Fiskenaesset ( Fiskenaes ), Nuuk region, western Greenland, which is where the mineral was discovered in 1819.
6. "' Sapphirine "'is a rare mineral, a silicate of magnesium and aluminium with the chemical formula ( synthesized for experimental purposes via a hydrothermal process.
7. Gedrite occurs in contact and medium to high grade metamorphic rocks in association with garnet, cordierite, anthophyllite, cummingtonite, sapphirine, sillimanite, kyanite, quartz, staurolite and biotite.
8. Khmaralite has a superstructure that is best described as a doubled sapphirine unit cell because the an axis is in the direction of the tetrahedral chains along which the main cation ordering occurs.
