Division of Island arc Metallogenic Series in Gubikou Ocean Basin

in Bikou volcanic rock series, a series of deposits such as iron, copper, lead, zinc, gold, silver and pyrite are produced. Under the theory of "metallogenic series", new resources as BIF type gold, jasper, and white marble, and also a large number of new deposits (spots), have been discovered in the new round of geological exploration fund project, further enriching the connotation of Bikou volcanic rock series. Most of these deposits are are superimposed by magmatic hydrothermal, volcanic hydrothermal and volcanic sedimentary minerals related to the original volcano in the later metamorphism and transformation.Based on the original division of regional metallogenic series, the redivision of metallogenic series is carried out taking Bikou Group as the unit. This research considers that Bikou-Yangba-heimulin is in the position of the island arc in ancient Bikou ocean basin. The island arc volcano has roughly experienced three major cycles, thus forming two metallogenic series and five metallogenic subseries. The result has a certain guiding role in mineral exploration in Bikou area.
