Discovery and Exploration Enlighten-ment of the Dawutang Extra Large Tungsten Deposit in the Jiangnan Tungsten Mine Belt
The Dawutang super large tungsten deposit is located in the Jiuling area of northwest Jiangxi,whose discovery is another major exploration achievement in the Dahutang ore concentration area of the Ji-angnan tungsten ore belt in recent years.Summarizing the exploration experience of this depositis important and inspirational for guiding a new round of breakthrough exploration in this area.The transformation of ex-ploration ideas from searching quartz vein type scheelite mineralization as the center target to focusing on fine vein disseminated scheelite mineralization controlled by hydrothermal fluids after the granite magma in-trusion as the main goal is the key point in the discovery of the Dawutang tungsten deposit.The Yanshanian fine-grained muscovite granite intruding in the Jinning period magmatic rocks is the most effective prospect-ing clue in this area,and the hidden explosive breccia is the mineralization center.Based on the characteris-tics of tungsten and copper deposits coexisting in the northwest region of Jiangxi,this paper proposes a pros-pecting approach of"searching for copper based on tungsten"in the Xiuwu area and"searching for tungsten based on copper"in the Jiurui area.
