| 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” |
| 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. |
