The "Four-dimensional Cracking and Putting together Restoration Law of Tectonic Rock Sheet" is an important method in the orogenic zone geological mapping in recent years. Using this method, this article discussed disputing problems on Runiange Formation in Luhuo-Daofu area, Sichuan Povince. From the view of the physical state, tense, phase, position and distortion, and the deterioration, the investigation indicated that the Runiange Formation structure is superposed longitudinally, being ordered generally and disordered partially.Laterally, various lothological layers do not extend stably, and constitute a large-scale structure lens network system. The geologic phenomena demonstrated that the Runiange Formation experienced the early deposition promiscuous action and the later structure promiscuous action; thus, the present typical orogenic zone non-Smith stratum body formed. This research not only enhances the Runiange Formation recognition degree, but also explains the primitive definition of the Runiange Formation.%"构造岩片四维裂拼复原法"是一种近年来在造山带地质填图中取得较大成就的方法.运用此方法对长期以来存在争议的如年各岩组进行了较为深入的解析,从物态、时态、相态、位态和变形、变质等多方面对其进行了调查和研究,认为如年各岩组在纵向上构造叠置,整体有序,局部无序;横向上各岩性层不能稳定延伸,构成大级别的构造透镜网络系统,显示如年各岩组经历了早期沉积混杂和后期构造混杂双重效应才构成了目前这样一套典型的造山带非史密斯地层体.这一研究成果不仅提高了如年各岩组的研究程度,而且重新阐述了如年各岩组的原始定义.
