PRELIMINARY APPLICATION OF THE TECTONIC SLICE MAPPING METHOD IN 1:50000 REGIONAL SURVEYS IN THE WESTERN SICHUAN OROGENIC BELT

摘要: 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。
