云南马关都龙超大型锡锌铜多金属矿床成因评述

Review of the genesis of Dulong Tin-Zinc-Copper polymetallic deposit in MaguanYunnan Province China

通过总结前人对都龙矿床的研究成果,从成矿物质来源、主要赋矿层位和成矿时代等几个方面着手,探讨了都龙矿床的成因。结果表明都龙矿床成矿物质具有多源性的特点,层状含矿矽卡岩的形成与热水沉积、区域变质和岩浆热液等地质作用均有一定的关系,成矿时代也存在多期性。都龙锌锡铜多金属矿床是热水沉积—区域变质—岩浆热液叠加共同作用的产物。

The author summarizes the predecessors＇research results of Dulong deposit ,and then tries to ex‐plore the genesis of Dulong deposit from many respects ,such as the sources of metallogenic materials ,the main ore‐bearing strata ,the metallogenic epoch ,and so on .T he results show that the metallogenic materials of Dulong deposit have the characteristics of multi‐source ;the formation of stratiform ore‐bearing skarn re‐lates with many geological actions of hydrothermal exhalative sedimentary ,regional metamorphism and magmatic hydrothermal activities ;the metallogenic epoch is characterized by multi‐period .Dulong tin‐zinc‐copper polymetallic deposit is the product of common actions of magmatic hydrothermal superimposition transformation and stacking interaction of hydrothermal exhalative sedimentary‐regional metamorphism re‐formation .
