二道河铅锌银矿床位于内蒙古扎兰屯市柴河镇西北部,是一个新近发现的铅锌银多金属矿床。据该矿床2012年详查结果,已探明的铅锌储量达到中型规模,具有较大的开发利用价值。由于该矿床发现较晚,加之该区植被覆盖严重,对该矿床成矿理论研究十分薄弱(王忠等,2012),笔者在对该矿床区域地质背景、矿床地质特征研究的基础上,探讨其矿床成因,以期为今后对该矿床的勘探及外围预测提供理论依据。
The Erdahe Lead-Zinc-Silver Deposit, located in the northwestern part of Chaihe Town, Zhalantun City, Inner Mongolia, is a newly discovered lead-zinc-silver polymetallic deposit. According to the 2012 detailed investigation of the deposit, the proven reserves of lead and zinc have reached the medium scale and have great value for development and utilization. Due to the later discovery of the deposit and the serious vegetation cover in the area, the research on the ore-forming theory of this deposit is very weak (Wang et al., 2012). On the basis of the study of the geological background and the geological characteristics of the deposit, The origin of the deposit is to provide a theoretical basis for future prospecting and peripheral prediction of the deposit.
