Hainan Mining Area is a mining area famous for its rich quality iron ore, copper, cobalt and other minerals.According to the achievements of predecessors and based on our geological exploration over the past few years, we have put forward the following understandings on the geological features and causes of the mining area I. Geological Profile of the Mining Area The tectonism of the mining area is located in the northwestern part of the South China Sea uplift of the Cathaysian fold belt in the South China Straddle Platform.The strata are mainly Cambrian-Ordovician (? ) Is a suite of shallow sea lacustrine facies consisting of sand shale, dolomite and argillaceous interbedded dolomite, with large changes in facies and thickness,
