| 摘 要： | 白腊水锡矿是新近发现的一个超大型锡矿床,主要由矽卡岩化破碎带蚀变岩型、蚀变岩体型和斑岩型等类型的锡矿脉组成。通过矿床地质特征、矿物包裹体特征和同位素组成的研究认为:①锡矿的产出严格受断裂构造控制,其中高序次断裂控制着锡矿带的展布,低序次断裂控制着矿脉(体)的分布及其形态、产状等;②由均一法测温得出锡多金属成矿期有3个成矿温度区间;③同位素组成显示成矿物质为深部来源,成矿时代为燕山早期;④矿床应该属严格受断裂构造控制的中-高温热液矿床。 |

| Abstract: | Bailashui tin deposits, situated in the south part of Qitianling r oc k body in Hunan province, are large-scale tin deposits that have been discovere d in recent years. It consists of forty tin lodes covering a variety of types su ch as the alteration rock type in the skarnized fracture zone, the alteration ro ck body type and the porphyry type. Research about the geologic characteristics, mineral inclusion characteristics and isotopic compositions of the deposits poi nts out that the deposits are hydrothermal deposits that were formed at middle t o high temperatures and strictly controlled by the Early Yanshanian fracture str ucture. |
| Keywords: | Bailashui tin deposits geological characteristics inclusion metal logenic epoch Hunan |
