| 摘 要： | 分布于塔惹增地区帕荣山一带的一套碎屑岩夹碳酸盐岩,对其时代归属缺乏可靠的古生物化石,一直颇有争议.前人根据岩性将其归为古近系日贡拉组,通过对此套地层详细的剖面研究表明其时代为上白垩统竟柱山组,其沉积环境为残留海相沉积,此套地层的时代厘定,为研究怒江洋在该地区的关闭提供了重要的基础地质资料.

| Abstract: | In Parong mountain of Tarezeng area, lack of fossil which can ensure the date of clastic rock nip carbonate rock is controversial. According to the lithology, the former researcher thought it belongs to Rigongla formation of Paleogene System. By study the section detailed, it proved that this strata is Zhushan formation of upper Cretaceous, it sedimentary environment is relict sea facies sediment. The determination of this strata affords important geological information for the study of the close of Nujiang river. |
