摘要
都龙锡锌矿是云南省典型的伴生铟的锡石-硫化物多金属矿床。通过对矿区曼家寨矿段含铟矿石的研究,可知都龙锡锌矿床中的In并不是以独立矿物的形式存在,而是主要赋存于铁闪锌矿中,以离子替代的方式进入富铟矿物的晶格中。In的含量与Sn、与Zn的富集呈正相关关系;In的富集受岩浆岩作用、构造作用和围岩作用影响;同时铟本身的成矿专属性也是铟富集的原因。
Dulong Sn-Zn deposit is a typical cassiterite sulfide multimetallic deposit with associated In in Yunnan.According to the study on In-bearing ore of Manjiazhai ore block in the orefield,we have determined the In of Dulong Sn-Zn deposit isn t occurred in independent form,but mainly in ferrian sphalerite,and into the lattice of In-rich mineral in ion metasomatism.The In content is in normal correlation with Sn,Zn concentration.The In concentration is affected by magmatic rock,structure and wall rock.And the In metallogenesis specialization is also the origin of In concentration.
