得耳布尔铅锌矿床属于典型的陆相火山－次火山热液矿床。通过对得耳布尔铅锌矿床地质特征的总结，分析了该矿床的控矿因素，提出正长斑岩体是矿床成矿地质作用的实物载体；次级断裂和地堑内部之间的弧形断裂或弧形断裂与次级断裂交汇部位为矿体提供了赋存的空间位置；铅锌银多金属成矿与上侏罗统塔木兰沟组地层密切相关，矿体形态、产状受构造控制明显，并指出寻找陆相火山－次火山热液型矿床的重要部位为经历了火山喷发、浅成岩浆就位产生的一系列环状、放射状断裂系统、破碎带、裂隙带等。
Derbur Pb-Zn Deposit belongs to typical continental volcanic-subvolcanic hydrothermal deposit.This paper,through summarizing the geological characteristics of Derbur Pb-Zn Deposit,analyzes the ore-controlling fac-tors of the deposit and puts forward that syenite phorphyry is the physical carrier in the mineralization process;it's the secondary faults and arc faults in the graben or the intersection of arc faults and secondary faults that provide the spa-tial location for the orebodies; the Pb-Zn -Ag polymetallic mineralization is closely related to the upper Jurassic Tamulangou formation strata, and the morphology and occurrence of orebodies are clearly controlled by tectonics. Meanwhile,it's pointed out that a series of ring and radial fracture systems, crushed zones and fissure zones going through the volcanic eruption and emplacement of hypabyssal magma are important locations for the seeking of conti-nental volcanic-subvolcanic hydrothermal deposits.
