| Abstract: | With geologic survey at Dinggu and Jiacuo on a scale of 1:250,000, plentiful sporo-pollen 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. |
| Keywords: | Cretaceous sporo-pollen fossils Jiacuo Qinghai-Tibet Plateau |
