Mineral dust deposition is suggested to be a significant atmospheric supply pathway of bioavailable iron (Fe) to Fe-depleted surface oceans.
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...
To simulate the discharge zone of hydrothermal systems in the laboratory, we developed a flow-type hydrothermal apparatus that can reproduce water–rock reactions at elevated temperatures and pressure...
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...
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...
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...

Abstract: The dissolution in 1 M HCl of Al-, Mn-, and Ni-substituted hematites and the influence of metal substitution on dissolution rate and kinetics of dissolution were investigated. The inhomogene...
Abstract: Selective-dissolution techniques by ammonium oxalate (OX), dithionite-citrate-bicarbonate (DCB), and dithionite-ethylenediaminetetraacetic acid (D-EDTA), and X-ray diffraction and M鰏sbauer s...
This study compared surface characteristics and dissolution behavior of well-crystallized (KGa-1b) and poorly crystallized (KGa-2) kaolinite standards. Atomic force microscopy (AFM) revealed that pa...

A combination of atomic force microscopy, scanning election microscopy, transmission electron microscopy, energy dispersive spectroscopy, electron diffraction, and X-ray dif-fraction were used to stud...

Abstract: The alteration experiments of phlogopite with 0.01 N HCl solution containing 0.1 M NaCl at 50°, 80° and 120°C have been carried out to aid in the understanding of the dissolution process of ...
