Experiments on co 2-brine-mineral interactions were designed to provide kinetic data for individual rock-forming minerals. Samples of an illite-smectite mixed layer mineral and a labradorite separate were stored in flexible ti-cells together with 2 m nacl brine and pure co 2 at 80 °c and 20 mpa for two and three weeks, respectively.

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible.
Moisture response functions for soil microbial carbon (c) mineralization remain a critical uncertainty for predicting ecosystem-climate feedbacks. Theory and models posit that c mineralization declines under elevated moisture and associated anaerobic conditions, leading to soil c accumulation. Yet, iron (fe) reduction potentially releases protected c, providing an under-appreciated mechanism.

Labradorite and oligoclase are the feldspar minerals that most often have aventurescence. In some localities colored but non-aventurescent labradorite is also called sunstone, but aventurescent material is usually mined nearby. Labradorite is sometimes intergrown in microscopic layers with albite or other plagioclase minerals. When light enters a polished gem and strikes these layers at just the right angle, the light is scattered, its wavelengths are modified, and an iridescent reflection.
