摘　　要：铂族元素是重要的战略性矿产资源,但难以形成独立矿床,多以伴生资源产出。秦岭造山带陕西段有形成铂族元素矿产的成矿背景,目前发现矿化信息较少。根据成矿环境、容矿岩石类型、共生元素组合、矿化类型等。铂族元素矿床主要分为铬铁矿型、铜镍硫化物型、碳酸岩脉型和沉积型。铂族元素以类质同象或吸附态形式赋存于金属硫化物或络合物中,其形成多与超基性岩或幔源岩浆、黑色岩系有关。开展秦岭造山带与超基性岩有关的铬铁矿、金属硫化矿和黑色岩系型多金属矿伴生铂族元素系统调查研究和找矿潜力评价,不仅可以开辟新区、新类型、新矿种的找矿思路,还可以扩大现有金属矿床的规模,增加伴生资源开发利用综合效益,为新一轮找矿突破助力。Platinum Group Elements(PGE)are vital strategic minerals,yet they rarely form independent ore deposits and are mainly produced as byproducts.The Qinling orogenic belt in Shaanxi holds potential for PGE mineralization,although little information on such deposits has been uncovered so far.Based on metallogenic conditions,host rock types,associated elements,and mineralization types,these deposits can be categorized into chromite type,Cu-Ni sulfide type,carbonate vein type,and sedimentary type.PGEs are found in metal sulfides or complexes,often in isomorphic or adsorbed forms,and are primarily associated with ultrabasic rocks,mantle-derived magmas,and black rocks.Conducting systematic investigations into the PGE metals associated with chromite,metal sulfide ores,and black rock type polymetallic ores in the Qinling belt,which are related to ultrabasic rocks,and assessing their prospecting potential,could lead to new areas,types,and minerals for prospecting.This effort could also expand the scale of existing metal deposits,enhance the overall benefits from associated resources,and support breakthroughs in the next round of ore prospecting.
