| 中文摘要: |
| 华北地区铅锌矿资源丰富、类型多样，是我国铅锌矿床的重要产区。本文在总结资源禀赋、矿床类型、时空特征、主要控矿因素、资源潜力等要素基础上，较全面分析了华北地区铅锌矿的主要特征和成矿规律。研究表明，从矿床成因角度，华北地区铅锌矿可划分为岩浆热液型、碳酸盐岩-细碎屑岩型、陆相火山岩型、矽卡岩型、斑岩型、碳酸盐型等6种类型，并可划归“层控”型和“岩控”型两大类；从矿产预测角度，又可划分为26个矿产预测类型，其中以碳酸盐岩—细碎屑岩型、岩浆热液型铅锌矿最为重要。基于华北地区铅锌成矿演化规律，华北地区铅锌成矿期可划分为中元古代、早古生代、晚古生代和中生代4个主要时期，中元古代、中生代是铅锌成矿的高峰期。华北地区铅锌成矿受控于区域构造、沉积-火山岩系、中酸性侵入岩等多种因素，经历了长期且复杂的构造演化，“层控”型和“岩控”型矿床的成矿环境各有不同，成矿作用特征具有明显差异。经综合评价，华北地区的铅锌成矿可划分为34个铅锌找矿远景区，显示出良好的找矿资源潜力。 |
| 英文摘要: |
| The North China is abundant with Pb-Zn resources and various genetic types occur thus is an important production area of Pb, Zn in China. Based on the resource endowment, deposit type, space-time distribution, main ore controlling factors and resource potential, this paper comprehensively analyzes the main characteristics and regional metallogeny. From the perspective of ore genesis, the Pb-Zn deposits in North China can be divided into six types: magmatic hydrothermal type, carbonate-fineclastic rock type, continental volcanic type, skarn type, porphyry type and carbonate type, which can be in turn classified into “stratabound” and “rock controlled” types. From the perspective of mineral prediction, lead-zinc deposits in North China can be divided into 26 types, of which SEDEX type and magmatic hydrothermal type are the most important. According to the temporal evolution the Pb-Zn mineralization can be divided into four main stages: Mesoproterozoic, Early Paleozoic, Late Paleozoic and Mesozoic, among which the Mesoproterozoic and Mesozoic are the peak periods. The Pb-Zn mineralization is controlled by many factors, such as regional structure, sedimentary-volcanic rock series, intermediate acid intrusive rock and so on and exposed to a long time and complex tectonic evolution. The “stratabound” and “rock controlled” deposits differ in ore-forming environments with obviously different mineralization characteristics. On the basis of the evaluation of mineral resources potential, 34 targets can be lineated. |
