| 摘 要： | 博格达山的构造演化及其造山作用的时间是一个长期争议且缺乏系统研究的问题。在野外调查的基础上,充分吸收前人成果,综合运用岩浆岩地球化学特征、不整合—沉积旋回、古流向及沉积物扩散方向等分析手段,对博格达山的构造演化进行了精细的剖析。结果表明:博格达山的构造演化主要经历了3期构造反转,即中—晚石炭世的裂陷海槽与晚石炭世末的弱造山期、早—中二叠世的裂陷盆地与晚二叠世—三叠纪和晚三叠世末的古博格达山隆升—夷平期以及早—中侏罗世的弱伸展盆地与晚侏罗世以来的现今博格达山阶段性隆升期;博格达山南缘柴窝堡凹陷地区印支期形成的NE向构造是油气勘探的有利区带。 |

| Abstract: | The tectonic evolution and the orogenic time of Bogda Mountain have been debated for a long time,and so far,few systematic researches have been done on this issue.In this paper,based on field surveys and preview papers,the tectonic evolution of Bogda Mountain has been studied elaborately with the application of several methods such as magmatite characteristic,sedimentary recycle,paleo-current direction and sediment dispersal patterns analysis.The results show that the tectonic evolution of Bogda Mountain mainly experienced three stages of tectonic inversion,i.e.(1) a rifted trough of Middle-Late Carboniferous and a weak orogeny period at the end of Late Carboniferous;(2) a rifted-basin of Early-Middle Permian and a paleo-Bogda Mountain uplift-leveling period from Late Permian to Triassic and at the end of Late Triassic;and(3) a weak-extensional basin of Early-Middle Jurassic and intermittent uplift periods of presentBogda Mountain from Late Jurassic to present.The structure belts with the northeast direction resulted from Indosinian movement in the Chaiwopu sag south to Bogda Mountain are potential exploration areas. |
| Keywords: | tectonic evolution tectonic inversion weak orogeny paleo-Bogda Mountain present-Bogda Mountain |
