摘　　要：广东丰顺县十字路矿区矿体主要赋存于早白垩世花岗岩体外接触带构造破碎带中,近矿围岩为侏罗系中-上统热水洞组流纹质岩屑晶屑凝灰岩。初步认为矿区浅部为脉状铅锌多金属矿、深部为斑岩型锡铜多金属矿体,矿床成因类型为与中酸性-潜火山岩有关的斑岩型矿床。The orebody of Shizilu orefield in Fengshun,Guangdng is mainly in the structual defracure zone of Early K granite outer contact,the wall rock near orebody is Middle-Upper J Reshuidong Formation liparite lithic crystallinoclastic tuff.We preliminarily think the veined Pb-Zn multimetallic ore is in the shallow part,whereas the porphyry Sn-Cu multimetallic orebody in the deep.It is a porphyry ore deposit related with intermediate-acid buried volcanite in genesis.
