| 中文摘要:钴、镍矿是我国战略性短缺矿产和战略性清洁能源矿产。河北省位于华北克拉通北缘东段, 已发现钴矿床、矿(化)点155处, 镍矿床、矿(化)点34处, 拥有较好的钴、镍矿成矿条件和找矿潜力。本文通过系统总结研究和典型矿床剖析, 梳理了河北省钴镍矿成因类型和时空分布规律, 划分了成矿区带和找矿远景区, 并提出了工作部署建议。将河北省钴镍矿(点)划分为与基性-超基性岩浆作用、接触交代作用、火山作用、含矿流体作用和沉积成岩作用有关的9种成因类型, 其中以岩浆型和矽卡岩型为主; 成矿时代自阜平期至燕山期均有出现, 其中矽卡岩型集中于燕山期, 岩浆型主要形成于晋宁期、华力西期和五台期。将河北省钴镍矿划分出5个Ⅳ级成矿亚带和5个Ⅴ级成矿小带, 并在成矿区带总结划分的基础上, 进一步提出了11处钴镍矿找矿远景区和20处找矿靶区。工作部署建议优先开展冀北岩浆型钴镍矿, 其次为冀西南矽卡岩型和火山块状硫化物-变质改造型钴镍矿, 从而为河北省钴、镍矿新一轮找矿突破奠定了基础。 |

| Abstract:China’s cobalt and nickel ores present strategic shortages of clean-energy minerals. Hebei Province is located in the eastern part of the northern margin of the North China Craton. A total of 155 cobalt deposits, ore points, and 34 nickel deposits were found that have good cobalt and nickel ore-forming conditions and prospecting potential. Through a systematic summary and analysis of typical ore deposits, this study presents the genetic types and temporal and spatial distribution patterns of cobalt-nickel deposits in Hebei Province, divides metallogenic belts and prospecting areas, and offers suggestions for work deployment. The cobalt-nickel deposits in Hebei Province are divided into nine genetic types related to basic-ultrabasic magmatism, contact metasomatism, volcanism, ore-bearing fluid, and sedimentary diagenesis, of which magmatic and skarn types are the main types. The metallogenic age occurs from Fuping to Yanshan, skarn is concentrated in Yanshan, and the magmatic type was mainly formed during the Jinning, Variscan, and Wutai periods. The cobalt-nickel deposits in Hebei Province are divided into five subzones of grade IV mineralization and five subzones of grade V. Based on the summary and division of mineralization zones, 11 cobalt-nickel prospecting areas and 20 prospecting target areas are proposed. Suggestions for work deployment include prioritizing the development of magmatic cobalt-nickel deposits in northern Hebei, followed by skarn-type and volcanic block sulfide metamorphic-modified cobalt-nickel deposits in southwestern Hebei, laying the foundation for a new round of exploration breakthroughs for Co and Ni in Hebei Province. |
