Other common minor constituents of eclogite include kyanite, orthopyroxene, rutile, amphibole, pyrite, and white mica. |
The mineral assemblage comprises quartz, K-feldspar, albitic plagioclase, white mica, apatite, tourmaline and garnet. |
There is a clear correlation between sieve fraction and apparent age for white mica separates. |
Secondary titanite, chlorite, white mica and pyrrhotite are abundant, and some samples contain metamorphic biotite. |
Thus, the competition between monovalent and divalent cations acts only on the DNA sites and does not act on the mica sites. |
Amazingly, the wind rose on the compass, and the original mica cover have survived intact. |
