Atmospheric dissolved iron deposition to the global oceans: effects of oxalate-promoted Fe dissolution, photochemical redox cycling, and dust mineralogy
global oceans oxalate-promoted Fe dissolution
2014/12/12
Mineral dust deposition is suggested to be a significant atmospheric supply pathway of bioavailable iron
(Fe) to Fe-depleted surface oceans.
Molecular-level mechanisms of quartz dissolution under neutral and alkaline conditions in the presence of electrolytes
quartz dissolution molecular-level mechanisms electrolytes pH conditions quantum chemistry calculation
2017/4/11
The mechanisms of quartz dissolution are affected intricately by pH conditions and electrolyte types. Most previous
studies have focused on the mechanisms of quartz dissolution under one specific con...
Elemental dissolution of basalts with ultra-pure water at 340°C and 40 MPa in a newly developed flow-type hydrothermal apparatus
hydrothermal system water–basalt reaction elemental dissolution flow-type experiment sub-terrestrial microbial ecosystem
2017/4/11
To simulate the discharge zone of hydrothermal systems in the laboratory, we developed a flow-type hydrothermal

Significant quantities of sulfidic sediments have been reported to have recently accumulated in inland wetlands of Murray Darling Basin due to a combination of long periods of inundation and the entra...
Dissolution processes of elements from subducting sediments into fluids: Evidence from the chemical composition of the Sanbagawa pelitic schists
element mobility subduction zones pelitic schists
2017/4/12
In order to evaluate the dissolution processes of elements from subducting sediments into fluids during early stages of
metamorphism (up to oligoclase–biotite zone at about 30 km depth), the chemical...
Desferrioxamine-B adsorption to and iron dissolution from palygorskite and sepiolite
DFOB Siderophore Fibrous clays Weathering Kinetic Isotherm
2011/11/4
Dissolution weathering of minerals can be greatly affected by the presence of siderophores and their adsorption in soil environments. In this research, adsorption equilibria and kinetics of desferriox...
