云南省芒市大矿山铅锌矿矿床控矿构造特征

The Ore-controlling Structure of Da kuang-shan Lead-Zinc Deposit in Mang city,Yun nan Province

矿区大地构造单元属冈底期—念青唐古拉褶皱系,潞西-畹町复式背斜带,位于芒市弧形构造带,该区具有良好的成矿条件,本文通过对该矿床控矿研究表明,矿区次级大矿山背斜是矿床的主要容矿构造,大矿山断裂的北段F6断裂为矿床的导矿构造,F5断裂为矿床的配矿构造。矿床类型为矽卡岩型矿床。

The mining ground tectonic unit belongs to the Okadi period-Niangqing Tangula fold system,the Luxi-Wanding duplex back slant belt,located in the arc-shaped tectonic belt of Mang City,the area has good mineralization conditions,this paper through the study of the mineral control of the deposit,The back slope of the secondary Da kuangshan in the mining area is the main capacity structure of the deposit,the northern section of the Da kuangshan break skewed the North section f6 fault is the guiding structure of the deposit,and the F5 fault is the distribution structure of the deposit.The type of deposit is the Rada rock deposit.
