GEOLOGICAL CHARACTERISTICS AND PROSPECTING ANALYSIS OF THE CIYUTAI MANGANESE DEPOSIT IN LIAONING PROVINCE

The Ciyutai manganese deposit of sedimentary metamorphic type dominated by manganese oxide, hosted in the first member of Tieling Formation, Jixian System, Mesoproterozoic, is the only manganese ore producer in Northern Liaoning Province. The ore hosting layer, which is mainly controlled by the Guguantun-Datun syncline, is stably and broadly distributed in the area. Recent research shows that the hinge zone of syncline, deep part of known ore bodies and the bottom of Mesozoic overburden in the south wing as well have a great prospecting potential, suggesting a breakthrough in the exploration for concealed and semi-concealed ore bodies in the area.
