  • Minerals Free Full Text Trace Elements in Magnetite

    Magnetite is a common accessory phase in various types of ore deposits. Its trace element content has proven to have critical implications regarding petrogenesis and as guides in the exploration for ore deposits in general. In this study we use LA ICP MS (laser ablation inductively coupled plasma mass spectrometry) analyses of trace elements to chemically characterize magnetite from the Pagoni

    The Candelaria orebody does not outcrop but is overlain by 100 200m of barren siliceous hornfels and calc silicate skarn. Copper sulphides occur as stringers, disseminations, breccia in fillings and mantos. The orebody measures one kilometer in length, 600 metres in depth and is being exploited by low cost, open pit bulk mining.

  • Abstract

    The relatively high vanadium content of the Ti magnetite in the Kennedy's Vale orebody (average of 2.0 to 2.2 weight % V 2 O 5) is consistent with melts sourced from the lowermost group of Ti magnetite layers in the Upper Zone. The internal zonation of the dyke is ascribed to contamination of melt with distance from the conduit.
