| 摘 要： | 通过1∶5万区域地质矿产调查,杂多然青走日麻一带新发现一套中泥盆世地层,结合岩石学、岩相学及古生物化石特征研究和对比,认为该地层与区域上出露于玉树县巴塘乡汹钦地区的中泥盆世汹钦组地层基本一致。由此推测在前人厘定的杂多地区早石炭世杂多群下部可能普遍存在该套地层,只是由于受调查精度限制,未能全部填绘出来。通过对新发现的中泥盆世地层的研究,为今后在该地区开展地质工作提供思路。

| Abstract: | Through the survey of 1 ： 50 000 regional geology and mineral resources, a set of Middle Devonian stratum is newly discovered in Ranqingzourima area of Zaduo county. Combined with the research and contrast of petrology, petrography and paleontology fossils characteristics, the authors think that this stratum is basically identical with the Middle Devonian, which exposed Xiongqin region of Batang township of Yushu county. And that this set of stratum might ist under the early carboniferous epoch in the Zaduo group, which had been divided by Just due to the limit of accuracy in the investigation,it failed to be fullly filled out. By characteristics of Middle Devonian stratum newly discovered, this article provides ideas work in the region for the future. regionally in generally expredecessors. analyzing the for geological |
