Ancient Microbes from Halite Fluid Inclusions: Optimized ...

Fluid inclusions in evaporite minerals (halite, gypsum, etc.) potentially preserve genetic records of microbial diversity and changing environmental conditions of Earth's hydrosphere for nearly one billion years. Here we describe a robust protocol for surface sterilization and retrieval of DNA from fluid inclusions in halite that, unlike previously published methods, guarantees removal of ...

C. Centrifugal force caused by the spin of the Earth on its axis contributes to the tide-generating force. D. Tides are generated partly due to gravitational pull of the Moon and (to a lesser extent) the Sun, and partly due to centrifugal "force" caused by motion of the Earth-Moon system around its center of mass.

Malachite - Wikipedia

Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
