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132种,查明资源量矿产98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,成矿强度最强的为受变质型、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。基于上述成果等资料,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。

Regional Metallogenic Regularity and Breakthrough Suggestions for A New Round of Mineral Exploration in Hebei Province
Abstract:Hebei Province has superior geological conditions for mineralization,abundant mineral resources,and distinct endowment characteristics; 132 types of minerals have been discovered, and 98 types of mineral resources have been identified, the advantageous minerals include 9 types such as coal, oil, natural gas, and iron. Based on previous geological and mineral data and achievements, the ore-forming units in Hebei Province have been identified as four III grade metallogenic belts, ten IV grade metallogenic sub belts, and seventeen V grade mining areas; the order of the advantages and disadvantages 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 periods. The number of deposit types shows an evolutionary pattern from few to many with geological age; Sixteen types of mineralization have been classified, with the strongest intensity being metamorphic type, magmatic hydrothermal type, terrestrial volcanic rock type, and biochemical sedimentary type; The mineralization process and mineralization combination show differences with the mineralization age and mineralization 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; Established a regional mineralization lineage. Based on the above achievements and other materials, a new round of strategic breakthroughs in mineral exploration has been preliminarily completed, including the selection of ore-forming prospect areas and the delineation of target areas. The experience of the new round of mineral exploration breakthroughs has been summarized in stages.The preliminary completion of the new round of strategic breakthroughs in mineral exploration has focused on the selection and delineation of prospecting areas and target areas, and the experience of the new round of mineral exploration breakthroughs has been summarized in stages.
