| 摘 要： | 通过对"东部高原"东北部地区中侏罗统—白垩系中黏土矿物分析,结果显示黏土矿物的组合及含量变化能够较好反映当时的气候、物源以及古地理变化;同时,伊利石结晶度不具有随地层深度发生变化的规律。黏土矿物组合以及伊利石结晶度在东部高原隆升与消亡前后,发生了比较明显的变化,这从另一方面反映了东部高原的存在。

| Abstract: | Research on clay minerals from the Jurassic-Cretaceous in Northeast of the "Eastern Plateau",China indicates that the change in clay mineral assemblage and content was related with paleoclimate,source and paleography,and IC did not vary with the depth of the stratum.The clay mineral assemblage and IC obviously varied before and after the uplift of the Eastern Plateau which suggested the existence of the plateau. |
