| 摘 要： | 羌塘盆地上侏罗统至下白垩统地层问题存在着多种意见 ,关键在于对雪山组的认识上。通过对羌塘盆地腹地半岛湖东北、长湖两剖面 ,雪山组在岩性特征、生物化石、地层接触关系及地质测年进行综合分析和讨论 ,认为雪山组是在白龙冰河组 (Kim meridgian— Berriasian)之上的陆相杂色碎屑沉积岩系。通过与雁石坪—安多地区雁石坪剖面和滇西剖面对比讨论 ,认为羌塘腹地的雪山组与雁石坪雪山组或扎窝茸组上部、滇西曼岗组层位相当 ,时代应为早白垩世中晚期

| Abstract: | Based on the comprehensive analysis and discussion, the Xueshan Formation is considered as a continental variegated clastic depositional rock series overlying the Balongbinghe Formation (Kimmeridgian—Berriasian) and based on the correlation of the Yanshiping Formation in the Yanshiping-Anduo area, the Xueshan Formation in the Qiangtang Basin is considered to be corresponding stratigraphically to Xueshan Formation in Yanshiping or the upper part of the Zhaworong Formation, being middle and late Early Cretaceous in age. |
