摘要
都龙锡锌多金属矿床位于云南省文山州马关县的东南部,是老君山成矿区内最为重要的锡锌矿床之一,是我国继云南个旧锡矿床和广西大厂锡矿床后的第三大锡矿床。在研究区域地质特征和矿床地质特征的基础上,通过对都龙锡锌多金属矿床的闪锌矿电子探针分析得出,矿床中的Zn元素置换了Fe元素,矽卡岩的形成温度逐渐降低,并且通过Fe元素和Zn元素的含量能够得出矿床的温度是由中温到中低温。
Dulong Sn-Zn Polymetallic Deposit is located in the southeast of Manguan County, Wenshan prefecture, Yunnan Province. It is one of the most important Sn-Zn polymetallic deposit in Laojunshan metallogenic area and the third largest tin deposit in China after Gejiu Sn Deposit in Yunnan Province and Dachang Sn Deposit in Guangxi Province. On the basis of geological features and ore deposit geology, through the analysis of Dulong Sn-Zn Polymetallic Deposit with the phalerite electron microprobe, it shows that the Zn deposit element displaces Fe element, and the formation of skarn temperature gradually decreases;and it can lead to that the temperature of the deposit changes from the medium temperature to low temperature through the contents of Fe element and Zn element.
