| 摘 要： | 云龙铁厂锡矿位于青藏滇缅"歹"字型构造收缩部位的澜沧江变质带中,属于东南亚锡矿带东支——滇泰锡矿带的北延部分之云龙锡矿带。矿化与燕山晚期—喜马拉雅期细粒二云母花岗岩有关,矿体多产在岩体舌状边缘及外接触带的层间剥离带或混合岩体内的构造裂隙中。矿石类型以锡石-电气石、石英型为主,锡石-硫化物型和锡石-角岩型次之,成因类型为混合岩化-高温热液矿床。以混合岩化、主干断裂及硅化、电气石化为本区重要找矿标志,通过对铁厂锡矿矿床地质特征及找矿标志的研究,对该区寻找同类型矿产具有积极的指导意义。

| Abstract: | Yunlong Tiechang tin deposit is located in -Burma structure shrinkage parts which shape like Asian tin belt-- Yidian Thai tin ore belt of northern the Lancang River metamorphic belt of Qinghai -Tibet ＂歹＂,, which belongs to the east branch of the Southeast extension part of the Yunlong tin ore zone. Mineralization is related to late Yanshan Himalayan fine two mica granite. Orebody procuced in the layers＇ fissures of rock＇s tongue edge outer contact zones or tectonic fracture in mixed rock. The ore types mainly are cassiterite- tourmaline and quartz, next for cassiterite sulfide and cassiterite - hornfels. Genetic type is chorismitization -hypothermal deposit. The important prospecting cariteria are chorismitization, main controlling fault and tourmalinization. Through study on geological characterisitics and prospecting criteria, there is positive guiding significance for searching similar deposit in this area. |
