Introduction
Research Area
Fig. 1 Tectonic framework of the Tibetan Plateau (Zhu D. C., 2013)
The study area is shown as a red rectangle in Fig. 1. It is located in south Tibet, straddling the middle segment of the Shiquanhe-Namu Co melange zone (SNMZ). The SNMZ is considered by some researchers as the boundary separating the Northern Lhasa terrain and the Central Lhasa Terrain.

The SNMZ juxtaposes Paleozoic strata against Yongzhu ophiolite and Selin Co Cretaceous basin strata.
Why Remote Sensing?
Limited field accessibility to conduct detailed field mapping.
Poor transportation
High altitude and topographic relief
Difficult to accurately map the boundaries of large-scale structural features like regional folds
Distinct lithologic units favor the application of the Remote Sensing technique
Clastic rocks (sandstone, wacke), limestone, felsic volcanic rocks, ultramafic rocks
Objectives
Mapping the general distribution of different types of rocks and different geological units
Mapping important geological boundaries, such as major faults
Mapping large-scale structures, such as regional folds
