Shijintan basic-ultrabasic rock body is a small copper-nickel mineralization rock that was recently discovered.The rock body is in the volcano stone tectonic melange zone and mineralized,it was composited of serpentinized dunite,olive two eclogite,gabbro,mafic to diabase;Metal mineral in pentlandite,chalcopyrite,pyrrhotite,magnetite ore rock;Comparison to the other ultrabasic rock body,Shijintan rock body has a low SiO2;high MgO,low TiO2,low magnesium iron characteristics;Aluminum supersaturation ANK greater than 1 and lower than the other body;Mg#value between79.99%- 81.19%,generally higher than Guaishishan and Heishan copper-nickel ore rock;Rare earth elements content was lower than the other body;Through analysis of geophysical and geochemical anomalies and surface mineralization body,conclude that Shijintan rock body has good mineralization potential.
