摘要
在1∶25万丁固、加措幅地质调查中,首次于加措地区红层中发现Schixzaeoisporites,Cyathidtes,Hammenia,Classopllis annulatus,Exespollenites等丰富孢粉化石,结合上、下地层安山岩的测年数据,从该套地层划出晚白垩世阿布山组,为该地区红层时代的归属提供证据。
With geologic survey at Dinggu and Jiacuo on a scale of 1 : 250, 000, plentiful sporo -poUen fossils of Schixzaeoisporites, Cyathidtes, Hammenia, Classopllis annulatus and Exespollenites, etc have been found at first within the strata on the Jiacuo district, in combination with year - measuring data of andesite of upper and lower layers, Abushan Formation of the Upper Cretaceous is plotted out from this set of strata which provide the evidence of the red bed ascribing over this area.
