Linxia Geopark is located on the east side of the Taizishan fold fault zone in the northern part of the West Qinling block, on the southern edge of the Tianshui-Linxia fault basin. The geological formation and structure in the area are relatively simple.  Magmatic rock: The geopark belongs to the Caledonian and the Yanshanian tectonic magmatic rock area. The magmatic activity is dominated by Early Paleozoic magmatism, supplemented by Mesozoic magmatism. The Ordovician intrusive rocks in the park are relatively developed, and the main rocks are granodiorite, quartz diorite, diorite, etc. Jurassic intrusive rocks are distributed in the vicinity of the geopark. Volcanic rocks are only seen in the Ordovician Wusushan Group in the northeast corner of the geopark. The rock units are mainly composed of gray-green, green-gray porphyritic glassy basalt, basalt, olivine basalt, basaltic andesite, weld volcanic breccia and rhyolite tuff. Paleoproterozoic strata and the strata are the Maxianshan Group (Pt1M.). The main rock types are Geological structure: The geopark is located in the Linxia Basin and its geological structure is North Fault and Maxianshan of Qilian Mountain, and is in southwest corner of the large Longzhong near-horizontal occurrence and generally unapparent structural deformation. However, the boundary fault of the West Qinling, since ~8Myr ago, has expanded from west to east to the interior developed growth strata and growth unconformities, recording the time and process of the Geological development history: The geological history of the geopark can be traced back since the Cretaceous. During the Cretaceous, this area has evolved into an inland basin, forming Movement at the end of the Late Cretaceous terminated the sedimentation history of the wide folds, thrust faults in the basin margin, intra-basin reverse and normal faults. As a result, the unconformity. The Cenozoic development history of the geopark is the evolution history of the Linxia Basin and of the mammals. In the Paleogene, the climate is hot and dry, the strata is primarily terrestrial clastic rocks characterized by orange-red, brick red rocks with a large and until the Miocene, was always in a warm and humid lake environment. The mammals in this platybelodon fauna and the late Miocene hipparion fauna. Since the middle Pliocene, owing to the deformation. From the early Pleistocene of the Quaternary, the lakes in the area gradually With the frequent fluctuations of the Quaternary climate, the equus fauna was extinct. By the late after the last glacial period, a great deal of ancient humans lived here, left many ancient human
