摘要
笔者在进行赣东北江南造山带印支—燕山碰撞造山后陆内变形演化与信江盆地充填系列研究中，利用ＴＭ遥感图像影像信息结合沉积建造分析，对白垩纪盆地中等时性地层界面进行识别与研究。本次识别的等时性地层界面类型有：古构造面、大面积冲蚀不整合界面、大面积超覆界面。这些界面的识别，从整体上保证了盆地沉积相三维空间配置的可靠性，为重塑盆地充填系列及构造演化阶段提供了新的信息。该方法丰富了陆相盆地分析的方法技术，可推动１∶５万区调中陆相盆地双重制图方法体系的建立。
sing the information of remote sensing and combining with the sedimentary formation analysis to pick out and study chronostratigraphic interface in cretaceous period basin in the course of studying intracontinental deformation evolution about North-eastern Jiangxi Jiangnan orognic belt and filling sequence of Xinjiang basin.Since three types of chronostratigraphic interfaces (Paleostructure interface, large regional erosional unconformites and overlap interface) have been picked out, it guarantees that the analysis of basin sedimentary facies is right. We can rebuild filling sequence and tectonic evolution stage of basin according to them. The method will become a new kind of methods in the course of terrestrial basin analysis in the future. It can push on founding method system of double mapping on terrestrial basin in 1:50 000 regional survey.
