The appellation structure of Lugu Lake
Geologically, Luguhu area belongs to the junction of Hengduanshan block fault zone and Kangdian Taibei oblique zone, and its formation period is relatively new, which was formed by neotectonic movement and external force dissolution in the middle Quaternary. Lugu Lake is a plateau fault subsidence lake, which consists of a northwest-southeast fault and two east-west faults.
Lugu Lake basin belongs to Bayan Kara geosyncline, Jinsha River fold system, and Paleozoic and Mesozoic strata in the lake area are developed. In Quaternary strata, only the gravel layer near the lake is seen, and there is no typical lacustrine deposit. Triangular faces and U-shaped glacial valley types of cliffs around the lake can be seen everywhere. The lake basin system is formed by fault depression and glaciation. Due to the influence of tectonic movement, the lake basin is surrounded by mountains, and the shores are mostly peninsulas and headlands.
