geology

geological structure

Minxian is a Hercynian fold belt in the North Branch of the West Qinling geosynclinal fold system. After the uplift of Yanshan movement in Mesozoic and the rise of Himalaya movement in Cenozoic, the present geomorphic pattern was formed. Its lithology is mainly composed of limestone, sandstone, peat and mudstone of the Paleozoic marine continental interbedding. In the southwest of the county, there are Cenozoic Tertiary red rocks and Quaternary loess. The loess is deep in Taohe area. The granites exposed in the lower meadows of min'e mountain, Mozhe and Lujing town are Indosinian intrusive rocks.

Stratigraphic rock

The strata in Minxian county are exposed from the Middle Devonian of Late Paleozoic to the Quaternary of Cenozoic. Cretaceous is absent in Mesozoic. The tertiary and Jurassic belong to continental Piedmont facies and inland lacustrine facies respectively, while the other strata belong to littoral and shallow marine facies with shallow metamorphism. Before Jurassic, the strata are all of light metamorphic slate, sandstone and limestone. There are contact metamorphic biotite schist, sericite schist, phyllite and breccia as well as dynamic metamorphic mylonite, breccia and phosphorite only on the edge of the immersion body and on both sides of the fault zone. Some strata before Jurassic were destroyed to a certain extent by the influence of intrusive rocks and faults. The Tertiary strata are distributed in the northeast of the fault. The Triassic strata are only exposed in the southwest of the fault. The county is divided into two parts: rock and rock.
