摘要
长春沟—达盖滩地区铅锌矿是最新发现的多金属矿床,矿床的形成与中生代构造岩浆活动与成矿作用的关系密切,矿化类型为热液充填型多金属矿。矿体呈脉状、似层状产出,矿化主要受北西向断裂带控制,严格受岩体和地层特定层位控制;化探异常与矿化带的分布密切相关,化探异常、围岩蚀变是重要的找矿标志。通过深入研究区域成矿地质背景和区内成矿地质条件,总结主要控矿因素、矿体特征、找矿标志,分析探讨了区内找矿前景,进而提出了进一步找矿方向。
The Changchungou-Dagaitan Lead-Zinc Deposit is a newly discovered polymetallic deposit, the formation of such ore deposits is closely related with Mesozoic tectonic magmatic activities and mineralization. The type of mineralization is hydrothermal filling polymetallic deposit. The ore layer is vein-like and layer-like, and mineralization is mainly controlled by the NW-trending fault zone, strictly controlled by the rock mass and specific stratigraphy horizon. The geochemical anomalies are closely related to the distribution of mineralization alteration zone. The geochemical anomaly and wall-rock alteration are important ore prospecting symbols. By further studying the geological background and ore-forming geological conditions in the region, the main ore control factors, orebody characteristics and prospecting criteria were summarized and the prospecting prospects were discussed, with further prospecting direction proposed.
