广东信宜―贵子地区锡矿床主要分为花岗斑岩型、云英岩型、石英脉型、锡石―硫化物(绿泥石)型、磁铁矿矽卡岩型五种。花岗斑岩型锡矿主要锡矿体产于燕山晚期花岗斑岩体的深部内外接触带上。云英岩型锡矿产于钾长花岗岩岩体隆起部位内接触带上，与岩体接触的围岩为震旦系云开群兰坑组。磁铁矿矽卡岩型锡矿产于钾长花岗岩体的外接触带的层间裂隙中，含矿层位主要为震旦系云开群罗罅组内透辉石榴石矽卡岩。石英脉型锡矿主要产于钾长花岗岩体的外接触带旁侧的次级断裂和裂隙中。锡石―硫化物(绿泥石)型锡矿主要产于钾长花岗岩、花岗斑岩体的顶部和外接触带变粒岩和片岩中，且受各种方向的构造裂隙或断裂控制。研究各类锡矿床主要特点及其控矿条件，分析该地区锡矿分布规律与找矿标志，对锡矿勘查工作具有指导意义。

The tin deposits in Xinyi-Guizi area of Guangdong have five types such as granite-porphyry type, greisen type,quartz vein type,cassiterite-sulfide (chlorite)type and magnetite-skarn type.The granite-por-phyry type tin deposits mainly occur in the deep endocontact and exocontact zone of late Yanshanian granite-porphyry rock bodies.The greisen type tin deposits occur in endocontact zone of uplifted part of moyite rock bodies,and the wall rocks in contact with the rock bodies are of Lankeng Formation of Yunkai Group of Sini-an System.The magnetite-skarn type tin deposits occur in the interlayer fissures of exocontact zone of moyite rock bodies,and the ore-bearing horizon is griquaite-skarn of Luoxia Formation of Yunkai Group of Sinian System.The quartz vein type tin deposits occur in the secondary fractures and fissures along the side of exo-contact zone of moyite rock bodies.The cassiterite-sulfide (chlorite)type tin deposits occur in granulite and schist on the top part and exocontact zone of moyite and granite-porphyry rock bodies and are controlled by structural fissures and faults in different directions.The study on primary characteristics and ore-controlling conditions of various types of tin deposits and the analysis on the distribution regularity and prospecting clues of tin deposits in this area have a guiding significance for exploration works of tin deposits.
