长岭子铅锌矿床位于黄岗—甘珠尔庙多金属矿带南部，该成矿带是大兴安岭南段地区最重要的银—铅—锌—铜等多金属成矿带。从地层、岩性和构造等方面入手对矿床地质特征及成因进行了探讨，认为Ⅰ号矿带成矿物质主要来源于二叠系碳酸盐岩，深源岩浆活动促使含矿热液形成和运移，并与碳酸盐岩发生接触交代作用，从而形成矽卡岩型锌多金属矿体；Ⅱ号矿带燕山期花岗岩分异出的含矿热液为成矿提供了热源和成矿物质，矿体产出方式为热液充填脉状，矿体的形成和分布受NE向断裂控制明显，形成了中温热液脉型多金属矿。

Changlingzi Lead-Zinc deposit is located in the south of Huanggang-Ganzhuermiao polymetallic ore belt，which is one of the most important Ag-Pb-Zn-Cu polymetallic metallogenic belts in the Southern Da Hinggan Mountains.Based on the strata，lithology and structure，the  geological characteristics and genesis of the deposit are discussed in this paper.It was thought that the Ⅰore belt of metallogenic material mainly comes from Permian carbonate rocks，deep source magma activity，the formation and migration of ore-bearing hydrothermal，and contact with carbonate metasomatism to form the skarn type zinc polymetallic ore body；Ⅱore zone of Yanshan period granite differentiation of ore and metallogenic hydrothermal ore-forming provide the heat source material，the occurence mode is hydrothermal filling vein，the formation and distribution of ore bodies are controlled by the north-east thrend structure significantly，formed the warm fluid pulse type metal body.
