摘　　要：我国处于"三面受挤压"、多旋回、多期造山运动的大地构造地质背景,多为叠合盆地展布,其"盆""山"耦合格局,基本上控制着油气田和金属矿床的分布。石油和天然气均产于现行盆地和残留盆地内。在石油、油层水中常含有Au、Ag、Hg、U、Fe等多金属组分;天然气中亦含有He、Xe等稀有元素。在盆地内或周边(山脉)常分布金、银、铅、锌、铀等多金属工业矿床共生或伴生,有的矿床规模已达大型、超大型。油气是来自盆地内"有机"和"无机"物质经一定温、压条件下,在"生、储、蓄、圈、移、保"封闭的还原环境下的产物;金属矿床是深部来自地壳、地幔含矿流体,多沿断裂构造密集、开放环境条件下卸载的结果。两者在空间上相互依赖、又相互分离的关系。研究其规律对当今深部找矿和找藏,具有重要的指导意义。China mainland is situated in a tectonic context of compression from three sides,multi-cycle and multi-phase orogenies,with many superimposed basins.The coupling pattern of basins and mountains largely controls the distribution of oil and gas fields as well as metal deposits.Oil and gas are produced in the current active basins and residual basins.The oil and reservoir water often contain Au,Ag,Hg,U,Fe and some other multi-metal components;natural gas often contains He,Xe and other rare elements.There are gold,silver,lead,zinc,uranium and many other metal deposits coexisting or associated within or around the basin （mountains）,some of which have reached the scale of large and super-large deposits.Oil and gas are the product of ＂organic＂ and ＂inorganic＂ substance from the basin under certain temperature and pressure conditions and also the closed reduction environment of ＂generation,reserve,accumulation,trap,migration,and ＂preservation＂;and metal deposits are formed by ore-bearing fluids from crust and mantle at depth,which are mostly released along faults in open environmental conditions.The above mentioned oil-gas and metal deposits are both interdependent and separated in space.The study of its a rule has an important guiding significance for prospecting of minerals and deposits at depth in the future..
