| 中文摘要: |
| 云南省马关县南捞锡多金属矿区位于滇东南老君山锡钨多金属成矿带上，成矿条件较为优越。矿区内锡钨多金属矿床的形成与花岗岩体的演化有着不可分割的亲缘关系，岩体控制了矿床的空间分布、矿床类型、金属矿床贫富，其作用是提供金属和介质，使之成为具有经济意义的矿床。通过对该矿床的成矿地质特征、矿化富集规律等总结，本文探讨了矿床成因及矿床工业类型，初步认为矿床成因属于燕山期中酸性岩浆活动有关的“中高温构造 -岩浆热液接触交代 ”型(矽卡岩型)锡多金属矿床。 |
| 英文摘要: |
| The Nanlao tin polymetallic mining area of Maguan County,Yunnan is located on the Laojunshan tin-tungsten polymetallic metallogenic belt in southeastern Yunnan with superior metallogenic conditions The formation of tin-tungsten polymetallic deposits in this mining area has an inseparable relationship with the evolution of granite The rocks control the spatial distribution,types and richness of metal deposits and provide metals and media to form the economically signi cant deposits By summarizing the mineralization geological characteristics and enrichment rules of the deposit,the genesis of the deposit and its industrial type have been discussed in this paper According to the discussion,it is preliminarily believed that the genesis of the deposit belongs to the “medium-high temperature structure-magmatic hydrothermal contact metasomatism”(skarn type) tin polymetallic deposit which is related to the Yanshanian intermediate-acid magmatic activity |
