摘　　要：锡矿是粤东优势矿种之一。在收集分析粤东莲花山地区61个锡矿床(点)成矿特征的基础上,对该地区锡矿床(点)矿产类型进行划分归类,建立了粤东莲花山地区锡矿工业类型,主要有为锡石-硫化物型、锡石-硅酸盐型、锡石-石英脉型、斑岩型4类;对4种不同类型锡矿床所具有的矿物组合进行归纳,并开展各类型代表性矿床综合研究,初步构建了4个类型代表性矿区的成矿模式图,为粤东地区锡矿研究提供了基础资料。Tin ore is one of the dominant minerals in eastern Guangdong Province.On the basis of collecting and analyzing the metallogenic characteristics of 61 tin deposits(points)in Lianhuashan area,eastern Guangdong Province,the tin deposit industry types in Lianhuashan area of eastern Guangdong Province have been established,which are classified into 4 kinds:cassite-sulfide type,cassite-silicate type,cassite-quartz vein type and porphyry type.At the same time,the mineral assemblages of 4 different types of tin deposits are summarized,and the comprehensive study of each type of representative deposits is carried out,and the metallogenic models have been preliminarily established,which can provide basic data for tin ore research in eastern Guangdong.
