中文摘要：
尚义盆地形成于早侏罗世-早白垩世，盆地内沉积了一套以紫红色、灰绿色陆源碎屑岩为主的地层，仅在晚侏罗世-早自垩世地层局部夹薄层玄武安山质火山岩。通过系统分析尚义盆地的沉积岩、沉积相带展布特征及古水流、砾石成分等，分析了早侏罗世-早白垩世盆地的物源区、汇水中心及古气候的演化，恢复了早侏罗世-早自垩世盆地古地理格局。同时，在前人研究基础上，结合尚义盆地的沉积-充填样式，重点总结和综合分析了盆地内熔积岩、辉绿岩、边界断层等的发育特征，初步推断晚侏罗世-早白垩世尚义盆地为伸展断陷盆地。
英文摘要：
Shangyi Basin was formed in the Early Jurassic to Early Cretaceous and mainly deposited a set of purple and celadon terrigenous clastic rocks, with a suit of thinner basaltic andesitic volcanic rock only found in the strata of the Late Jurassic to Early Cretaceous. The provenance, catchment center and palaeoclimate were analysed through the systematic analysis of the sedimentary rocks, distribution characteristcs of sedimentary facies, palaeocurent, gravel components etc., and a evolution model of palaeogeography of Shangyi Basin was reconstructed. Meanwhile, based on previous study results, combining with the depositional and filling pattern of Shangyi Basin, the characteristics of peperite, dolerite and boundary faults were summarized and analysed, and Shangyi Basin was deduced to be an extensional faulted basin during the Late Jurassic to the Early Cretaceous.
