摘要:Abstract(#br)This paper reviews the occurrence of platinum-group elements nanoparticles (PGE-NPs) in mantle-hosted chromite deposits, showing that PGE-NPs are more frequently found in these deposits than previously thought. A comparison of published experimental data with obser...

摘要:...(#br)Mineral inclusions in chromite from the Wafangdian kimberlite, Liaoning Province, China were used to demonstrate the applications of electron probe microanalysis and microscopy technique in characterizing minerals associated with ore deposits, specifically, in this p...

摘要:... These rocks host voluminous chromite deposits with lenticular or vein-like shapes. The podiform chromitites are associated with, and cross-cut by, numerous troctolite dykes. Chromite in the chromitites has Al 2 O 3 (23–31 wt%), TiO 2 (0.29–0.44 wt%), and Cr 2 O 3 con...

摘要:Abstract(#br)The Jacurici Complex, located in the NE part of the São Francisco Craton, hosts the largest chromite deposit in Brazil. The mineralized intrusion is considered to be a single N-S elongated layered body, disrupted into many segments by subsequent deformation. The ...

摘要:Abstract(#br)Chlorite occurring in tremolite-chlorite schist rock of Byrapur chromite deposit of southern India has been investigated by 57 Fe Mössbauer spectroscopy along with XRD, IR and EPMA analyses. From XRD and EPMA results the chlorite is identified as clinochlore. The f...

摘要:... The Dehsheikh massif consists of relatively unaltered harzburgite, lherzolite, dunite and several chromite deposits that are cut by pyroxenitic dykes. These peridotites display numerous evidences of mantle metasomatism at various scales. Dunite dykes, bands and patches as we...

摘要:... These BMS were found forming composite inclusions (<60 μm across) within larger unaltered chromite from the Caridad chromite deposit, which is hosted in the mantle section of the Mayarí-Baracoa Ophiolite in eastern Cuba. Electron probe microanalysis of BMS revealed PGE va...

摘要:Abstract(#br)I have oversaturated the immiscible system SiO 2 Al 2 O 3 FeO K 2 O with FeCr 2 O 4 to study the fractionation of chromite between conjugate siliceous and fayalitic melts. Although both melts are oversaturated with chromite, chromite only nucleates in the fayalit...
