Fate of copper complexes in hydrothermally altered deep-sea sediments from the Central Indian Ocean Basin.
The current study aims to understand the speciation and fate of Cu complexes in hydrothermally altered sediments from the Central Indian Ocean Basin and assess the probable impacts of deep-sea mining on speciation of Cu complexes and assess the Cu flux from this sediment to the water column in this area. This study suggests that most of the Cu was strongly associated with different binding site...

متن کاملPossible structure types derived from Pbca - orthopyroxene TAKEO
The possible structure types derived from the Pbca-orthopyroxene are shown. There are sixteen space groups, as subgroups of Pbca, without destroying the original unit-cell type setting. Five structure types have two kinds of tetrahedral chain, nine types have four kinds of tetrahedral chain and two types have eight kinds of tetrahedral chain, respectively. Introduction Since the first structure...
متن کاملMechanisms of arsenic and lead release from hydrothermally altered rock.
This paper describes the effects of pH, dissolved oxygen (DO), redox conditions, and mixing ratio of different rocks on the leaching behaviors of As and Pb from hydrothermally altered rock as well as the functional groups incorporating As and Pb in the rock. Most of As and Pb were incorporated in the residual or crystalline phase although significant amounts were also determined to be exchangea...
متن کاملSolubility of andradite, Ca3Fe2Si3O12, in a 10 mol% NaCl solution at 800 °C and 10 kbar: Implications for the metasomatic origin of grandite garnet in calc-silicate granulites
The solubility of andradite garnet was determined at 800 °C and 10 kbar in a solution of 10 mol% NaCl and 90 mol% H2O. Experiments were syntheses carried out with high-purity natural wollastonite, reagent hematite or natural specular hematite containing ~1 wt% TiO2, and fluid. All experiments were performed with Mn2O3-Mn3O4 or Fe2O3-Fe3O4 oxygen buffers in a piston-cylinder apparatus with NaCl ...
