Structural and Stratigraphic Analysis of the Runiange Formation in Luhuo-Daofu Area, Sichuan Province

Abstract

Abstract:

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 Province. 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.

Key words: Runiange Formation；structure, stratigraphy, LuhuoDaofu area, Sichuan Province
