摘　　要：【研究目的】河北省冀北地区地处华北克拉通北缘东段附近,位于华北克拉通北缘岩浆型钴镍矿成矿远景区内,钴镍矿化线索较为丰富。通过总结研究河北省钴镍成矿条件和类型,有助于明确省内钴镍矿成矿潜力和找矿远景。【研究方法】通过总结分析国内外典型钴镍矿床,类比河北省内成矿地质条件;综合分析相关地质、矿产资料,总结研究区钴镍矿成矿背景、成矿规律和找矿潜力。【研究结果】河北省内与钴镍成矿有关的基性-超基性岩体数量众多,与钴镍成矿有关的地层和区域构造广泛分布,钴镍成矿地质条件较为优越;将省内已知钴镍矿(化)点,划分为与侵入岩浆作用、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种钴镍矿成因类型,并对各类型钴镍矿的成矿作用、矿(化)点分布及数量等特征进行了总结。【结论】河北省钴镍矿成矿地质条件优越、成因类型丰富多样,特别是岩浆型和矽卡岩型有着较好的成矿潜力和找矿远景。This paper is the research on cobalt-nickel deposits.[Objective]Northern Hebei is located near the eastern part of the northern margin of the North China Craton,which is in the metallogenic prospect area of magmatic cobalt-nickel deposits on the northern margin of North China Craton,and there are abundant clues to cobalt-nickel mineralization.The study of the metallogenic conditions and types of cobalt-nickel deposits in Hebei Province is helpful to clarify the metallogenic potential and prospecting prospect of cobalt-nickel deposits in the province.[Methods]By summarizing the typical cobalt-nickel deposits at home and abroad,the ore-forming geological conditions in the province are compared.Based on the comprehensive analysis of relevant geological and mineral data,the metallogenic background,metallogenic regularity and prospecting potential of cobalt-nickel deposits in the province are summarized and analyzed.[Results]There are a large number of basic-ultrabasic rock bodies related to cobalt-nickel mineralization in the province,the strata and regional structures related to cobalt-nickel mineralization are widely distributed,and the cobalt-nickel ore-forming geological conditions are superior.The known cobalt-nickel deposits in the province are divided into nine genetic types of cobalt-nickel deposits related to intrusive magmatism,contact metasomatism,volcanism,ore-bearing fluid and sedimentary diagenesis,and the characteristics of mineralization,distribution and quantity of various types of cobalt-nickel deposits are summarized.[Conclusions]The nickel-cobalt deposits in Hebei Province have superior ore-forming geological conditions,rich and diverse genetic types,especially magmatic and skarn types have good metallogenic potential and prospecting prospect.
