摘　　要：为摸清青藏高原北部煤系矿产资源的种类和分布状况,开展了青藏高原北部成煤地质背景和煤系矿产资源特征研究。通过实地调查、典型样品测试及资料综合分析,总结出青藏高原北部主要成煤时代为早石炭世、晚石炭世、晚二叠世、晚三叠世及早中侏罗世,煤系可划分为昆仑山、积石山、唐古拉山、土门—巴青、昌都—芒康等5个赋煤带;主要的煤系矿产有煤炭、煤系气、天然气水合物、煤中锗镓以及煤系石膏、高岭土、优质灰岩等。在成煤环境、煤化作用、构造演化等的共同作用下,尕马羊曲地区形成煤-煤中锗共生矿床;开心岭—乌丽地区形成煤-煤系气-天然气水合物共生能源矿床;唐古拉山地区的巴贡组(T3bg)、那益雄组(P3n)、杂多群(C1zd)、加卖弄群(C2j)均具有形成煤-煤层气-煤系页岩气共生能源矿床的资源潜力。To investigate the types and distribution of coal resources in Northern Qinghai Tibet plateau,the coal geolog-ical background and characteristics of coal resources in Northern Qinghai Tibet plateau were investigated. On the basisof field survey,typical samples test analysis and comprehensive analysis,the main coal area are divided into early Car-boniferous and late Carboniferous,late Permian,late Triassic,early and middle Jurassic. Coal measures are mainly dis-tributed in the Kunlunshan, Jishishan, Tanggulanshan, Tumen-Baqing, Changdu-Mangkang coal belt, etc. The mainproducts related with coal include coal,coal unconventional gas,natural gas hydrate,coal gallium,coal germanium,coal gypsum,coal kaolin and high-quality limestone,etc. Under the action of coal forming environment,coalificationand tectonic evolution,Coal-Germanium in coal symbiotic deposit formed in Gama Yangqu region;Coal-coal gas-gashydrate symbiotic deposit formed in Kaixinling-Wuli region. The formations of T3 bg,P3n,C1 zd and C2j all have the po-tential of forming coal-coal gas-coal shale gas hydrate symbiotic deposit.
