Metallogeny of Serpentinite‐hosted Magnetite Deposits: Hydrothermal Overgrowth on Chromite or Metamorphic Transformation of Chromite?

Chromite – Platinum-Group Element Magmatic Deposits

Chromite chemistry in SNC meteorites

Hydrothermal phase transformation of hematite to magnetite

Different phases of iron oxide were obtained by hydrothermal treatment of ferric solution at 200°C with the addition of either KOH, ethylenediamine (EDA), or KOH and EDA into the reaction system. As usually observed, the α-Fe2O3 hexagonal plates and hexagonal bipyramids were obtained for reaction with KOH and EDA, respectively. When both KOH and EDA were added into the reaction system, we obser...

The Spatial Distribution of Some Chromite Deposits in Iran, Using Fry Analysis

The spatial distribution of mineralization is the foremost concern in regional exploration and it could be considered as a very important tool in the investigation of mineral deposits. There are several data manipulation methods by which the data can be evaluated. Fry analysis is a good method to determine the direction(s) of maximum continuity of the deposits and could be used in different typ...

Novel preparation of highly photocatalytically active copper chromite nanostructured material via a simple hydrothermal route

Highly photocatalytically active copper chromite nanostructured material were prepared via a novel simple hydrothermal reaction between [Cu(en)2(H2O)2]Cl2 and [Cr(en)3]Cl3.3H2O at low temperature, without adding any pH regulator or external capping agent. The as-synthesized nanostructured copper chromite was analyzed by transmission electron microscopy (TEM), UV-vis diffuse reflectance spectros...
