| 中文摘要:河北省成矿地质条件优越, 矿产资源丰富, 禀赋特点鲜明; 已发现矿产115种, 查明资源量矿产 94种, 优势矿种为煤、石油、天然气、铁等9种。基于以往地质矿产资料与成果, 确定了河北省成矿单元为４个Ⅲ级成矿带、10个Ⅳ级成矿亚带、17个Ⅴ级矿集区。厘清了Ⅲ级成矿单元矿产资源优劣顺序为华北陆块北缘成矿带→山西断隆成矿区→华北盆地(断坳)成矿带→突泉—翁牛特成矿带; 成矿强度排序前六的成矿时代依次为古近纪、石炭纪—二叠纪、新太古代、白垩纪、中元古代、奥陶纪; 矿床类型数量随地质年代呈现出由少到多的演化规律; 划分了16种成矿类型, 成矿强度较强的成矿类型是受变质型、岩浆热液型、陆相火山岩型和生物化学沉积型; 总结出成矿作用与矿化组合随成矿时代与成矿单元呈现出差异性。厘定出矿床成矿系列组14个, 矿床成矿系列39个, 矿床成矿亚系列46个, 矿床式或典型矿床97个; 建立了区域成矿谱系。基于上述成果, 初步完成了新一轮找矿突破战略行动成矿远景区优选与靶区圈定工作, 阶段性地总结了新一轮找矿突破工作经验。 |

| Metallogenic Regularity of Hebei Province, and Suggestions for a New Round of Prospecting: Research and Compilation of “Geology of Mineral Resources of China • Hebei Volume” |

| Abstract:Hebei Province is endowed with superior geological conditions for mineralization and thus abundant mineral resources; 115 types of minerals have been discovered and 94 types of mineral resources have been identified with 9 types advantageous minerals including coal, oil, natural gas, and iron. Based on previous geological and mineral data, the ore-forming units in Hebei Province have been categorized into four grade III metallogenic belts, ten grade IV metallogenic sub belts, and seventeen grade V mining areas. The order of prospect value of mineral resources in level III mineralization units has been clarified as follows: North margin mineralization belt of the North China Block > Shanxi fault uplift mineralization area > North China Basin (fault depression) mineralization belt > Tuquan Wengniute mineralization belt. The top six mineralization periods in terms of mineralization intensity are the Paleogene, Carboniferous, Permian, Neoproterozoic, Cretaceous, Mesoproterozoic, and Ordovician. The number of deposit types shows an evolutionary pattern from few to many with geological age. 16 types of mineralization have been classified, and the mineralization types with the stronger mineralization intensity are metamorphic type, magmatic hydrothermal type, terrestrial volcanic rock type, and biochemical sedimentary type. The mineralization process and mineral content differ based on the mineralization age and unit. 14 ore deposit series groups, 39 ore deposit series, 46 ore deposit sub series, and 97 ore deposit types or typical ore deposits have been identified. A regional mineralization lineage has been established. Based on the above achievements and other materials, a new round of prospecting has been preliminarily completed, including the selection of ore-forming prospecting areas and the delineation of target areas. The experience of the new round of prospecting has been summarized periodically. |
