摘要
根据地层学研究的新进展，将原乐平组的官山段和下老山段划归茅口阶，编制了这一时期的沉积断面图，并对这一时期的沉积史进行了阐述。
The tectono stratigraphic division of exposed crust section of Jianglang metamorphic core complex in the western margin of the Yangtze Craton includes three systems, i.e, the stacking stratigraphic system of Mesoproterozoic Liwu rock Group reformed for a few regimes and generationes and represented the basement of the Yangtze Craton; the Paleozoic folding layer (fluid crust layer) system which includes three rock associations, i.e, Wulaxi, Jiaba and Jianglang rock formations, their ages are Permian, Early Silurian and Ordovician respectively; the slate belt of Triassic Xicang Group reformed in shallow tectonic level, which is the upper part in the three systems. Between the systems, or in each system, a series of layered denudational faults were developed, and the most important one is on the top of Jianglang metamorphic core complex which is named basement denudational fault belt.
