| The binding of a DNA molecule to freshly cleaved mica surface in solution has also been measured. |
| 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. |
| There is a clear correlation between sieve fraction and apparent age for white mica separates. |
| Corundum occurs as an accessory mineral in some metamorphic rocks, such as mica schist, gneiss, and crystalline limestone. |
| Her collection is not large, but it includes mica, aquamarine, tourmaline, and other pretty stones. |
