Brucite formation and dissolution in oceanic serpentinite

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

On the Formation of Brucite and Cronstedtite on Ceres

Direct synthesis of hexagonal Mg(OH)2 nanoplates from natural brucite without dissolution procedure.

A facile, dissolution-free route to direct synthesis of hexagonal magnesium hydroxide nanoplates from natural brucite is reported. Stable brucite undergoes disaggregation into thin nanosheets and subsequent solid-solid transformation in the presence of p-toluene sulfonate, circumventing the threshold of size effect from bulk brucite to Mg(OH)(2) nanoplates.

Planktonic Foraminifera of the Dariyan formation and implications of Oceanic Anoxic Event 1a

The investigated section cropping out in Kuh-e-Banesh, Zagros basin (southern Iran) is represented by limestone, Cherty beds and marllevels bearing abundant Planktonic foraminifers, radiolarian microfaunas, and ammonite imprints. For the first time, well to moderatelypreserved forms of Planktonic foraminifera have been extracted from black shale and marls levels. Extracted biota was studied wit...

Fluid mixing and the deep biosphere of a fossil Lost City-type hydrothermal system at the Iberia Margin.

Subseafloor mixing of reduced hydrothermal fluids with seawater is believed to provide the energy and substrates needed to support deep chemolithoautotrophic life in the hydrated oceanic mantle (i.e., serpentinite). However, geosphere-biosphere interactions in serpentinite-hosted subseafloor mixing zones remain poorly constrained. Here we examine fossil microbial communities and fluid mixing pr...
