sillimanite मीनिंग इन हिंदी

उदाहरण वाक्य

1. At higher temperatures and pressures, andalusite may convert to sillimanite.
2. Unusual minerals found in the volcanics include andalusite, muscovite, sillimanite and tourmaline.
3. Andalusite is trimorphic with kyanite and sillimanite, being the lower pressure mid temperature polymorph.
4. Other possible minerals formed at dry conditions include sapphirine, spinel, sillimanite, and osumilite.
5. Kyanite is triclinic, while andalusite and sillimanite are both orthorhombic and belong to the dipyramidal point group.
6. These minerals, known as index minerals, include sillimanite, kyanite, staurolite, andalusite, and some garnet.
7. The Angara-Kan terrane also includes two pyroxene plagioclase and one garnet-biotite-sillimanite-cordierite gneisses.
8. In a few cases rocks are fused and in the dark glassy product minute crystals of spinel, sillimanite and cordierite may separate out.
9. The mineral occurs as exsolution lamellae and particles in rutile, coexisting with kyanite, sillimanite, and tourmaline in a highly metamorphosed gneiss.
10. Andalusite is stable at low pressure, kyanite is stable at high pressure but relatively low temperature and sillimanite is stable at high temperature.
