MINERALIZTION ENVIRONMENT AND REGULARITY OF MESOZOIC ERA VOLCANIC Au-Ag DEPOSIT IN ZHEJIANG-FUJIAN-GUANGDONG REGION AND ITS PROSPECTING CRITERIA

摘要

The geological environment for mineralization and the geological characteristics andrnmineralization regularities in special of the Mesozoic era volcanic Au-Ag deposits, in Zhejiang, Fujian and Guangdong Provinces, have been investigated. And it is pointed out that the prospecting criteria for this region can be summarized as two zones. three swells. three formations and seven areas; the majorrnprospecting targets are four zones. one point and one anormaly, those are stated in detail in the paperrnrespectively.
