作者通过川西造山带1:5万区调实践,初步提出了构造岩片填图法:首先测制构造-地层综合剖面,填制带状构造-岩性图(走廊地质图),初步判断分区主断面,划分构造岩片,建立各岩片的岩石地层拄或构造地层柱,确定正式和非正式的填图单位;第二是联带成面;第三是全面综合研究,典型解剖,完善测区构造宕片及其岩石地层和构造岩石地层单位的划分;最后是完成组图的编制。
Through the practice of 1: 50000 regional adjustment in the western Sichuan orogenic belt, the authors initially proposed tectonic mapping: firstly, the tectonic-stratigraphic comprehensive profile was measured and the banded structure-lithology map (corridor geological map) was filled in; Section, the division of structural slices, the establishment of rock strata Zhu Zhu or structural stratigraphic column, to determine formal and informal mapping units; the second is the joint into the surface; the third is a comprehensive and comprehensive study of typical anatomy and improve the structure of the test area Daping and its rock stratigraphy and tectonic lithostratigraphic unit division; Finally, the completion of the compilation of the group diagram.
