Which place in Yunnan has more mineral resources?

Yunnan has a complex geological structure and is rich in metallic and nonmetallic minerals. Non-metallic minerals are most widely distributed in coal, among which Carboniferous and Permian are the most important in Paleozoic coalfields. Mesozoic coalfields are mainly produced in Triassic; Cenozoic coalfields are produced in tertiary strata, mainly lignite. Phosphate rocks were formed in Meishucun Formation of Early Cambrian. Non-metallic minerals such as rock salt, potassium salt and gypsum were formed in Mesozoic. Metal mines are mainly non-ferrous metal mines, with many kinds and large reserves, especially Gejiu tin mine, Dongchuan copper mine and titanium mine, which are among the best in the country. It is called "Kingdom of Nonferrous Metals", and its shape was greatly influenced by Yanshan Movement. Some iron ores were formed in early metamorphic rocks, but also in shallow-sea sedimentary iron ores in Devonian sandstone.

Metallurgical industry is mainly engaged in the mining and smelting of non-ferrous metals, and it is an important non-ferrous metal production base in China. Among them, Gejiu tin mine is world-renowned, with the national output ranking 1, enjoying the reputation of "tin capital"; Dongchuan, Yimen and Yongsheng are the main copper-producing areas. The copper produced in Dongchuan Copper Mine is silvery white, which is called "Yunnan Copper". Lanping lead-zinc mine has large and concentrated reserves, high grade, easy mining and large smelting scale, followed by Yi Hui and other places. In the iron and steel industry, the output of steel, pig iron and steel increased the fastest. Among them, high-quality small profiles are basically self-sufficient. Kunming Iron and Steel Plant near Anning has developed into a medium-sized iron and steel complex integrating mining, ironmaking, steelmaking and steel rolling. (z China Mineral Trade Network)
