Summary of Regional Metallogenic Regularity in Ningxia

Although Ningxia is small in area, there are many kinds of mineral resources, including energy, metal, nonmetallic and groundwater - gas minerals. More than 60 kinds of minerals (including subminerals) have been discovered, of which more than 50 kinds of minerals have proved reserves. Coal, gypsum, limestone, magnesia dolomite, silica and other dominant minerals. This paper summarizes the time-space distribution evolution of mineral resources in Ningxia: The time can be divided into Proterozoic, Paleozoic, Mesozoic and Cenozoic. The non-metallic minerals reached their metallogenic peak in Caledonian and Himalayan ages, the metallic minerals in Jinning and Yanshanian ages, the energy minerals in Hualissian and Yanshanian ages, and the water-gas minerals in Himalayan ages. In space, 12 grade Ⅴ structural units in Ningxia are used as the basic spatial units: Metal minerals are mainly concentrated in Helan Mountain, Weining North Mountain and South-West Huashan region. Non-metallic minerals are mainly concentrated in helan Mountain fold and Xiangshan fold, followed by Yandong Shan-Yaoshan thrust belt and Taole-Pengyang thrust belt. Energy mineral resources are concentrated in taole - Pengyang thrust belt. Most of the hydrogas minerals are concentrated in yinchuan fault depression basin. Most of the groundwater - gas minerals are concentrated in Yinchuan fault depression basin. On the basis of comprehensive digestion of existing geological and mineral data. The whole area of Ningxia is divided into 9 grade IV metallogenic subbelts and 19 ore clusters or prospective areas. Nine ore-forming series and 10 ore-forming subseries were determined and regional metallogenic genealogy was established.
