摘要
瑶岗仙矿床是南岭地区典型的石英脉型黑钨矿床,并伴生石英脉型和矽卡岩型两类白钨矿化。经过野外地质现象系统的观察以及精细的镜下矿物学研究,厘定了两种类型白钨矿化的成矿阶段,对不同类型白钨矿进行了宏观和微观地质特征对比。结果表明,石英脉型和矽卡岩型白钨矿的成矿环境、成矿规模、显微组构等有着明显区别。通过对比两种矿体白钨矿的岩相学特征,约束不同类型白钨矿的成矿过程与成矿作用。
Yaogangxian deposit is a typical quartz-vein type wolframite deposit in Nanling area,accompanied by two types of scheelite mineralization:quartz-vein type and skarn type.Through systematic observation of field geological phenomena and fine mineralogical study under microscope,the metallogenic stages of the two types of scheelite are determined,and the macroscopic and microscopic geological characteristics of different types of scheelite are compared.The results show that there are obvious differences between quartz-vein type scheelite and skarn type scheelite in metallogenic environment,metallogenic scale and microstructure.By comparing the petrographic characteristics of scheelite in two ore bodies,the metallogenic process and mineralization of different types of scheelite are restricted.
