| 摘 要： | 在藏北申扎地区塔尔玛-新吉中新生代沉积盆地北缘发现一套厚1 000 m灰岩夹碎屑岩岩段。岩层呈近东西向展布,南部两侧均被断层所切割,未见顶底。其内含较丰富的早白垩世海相动物化石,在这个地区尚属首次发现,确定了1∶25万申扎县幅内及周边地区有早白垩世的海相地层的存在,为研究班戈—怒江缝合带和雅江缝合带构造格局提供了新材料。 |
| 关 键 词： | 西藏北部 申扎地区 白垩系 海相动物化石 |

| Abstract: | A set of limestone with clastic rock which contains a lot of the early Cretaceous marine zoolites about 1 000 m thick developed along the northern margin of the intermediate Cenozoic,Taerma-Xiji sedimentary Basin,Shenza area of Tibet,the strata show sub-EW trend,the two sides of the southern part were cut by the faults.It is the first time to discover the strata based on reliable fossils,which provides useful evidence to the research of Bange-Nujiang and Yarlung-Zangbo suture zone. |
