Midu Spa Geological Features And Genesis Mode Analysis

Clean and low consumption energy in our great requirements, geothermal energy becomes a more important one, showing it's unique and more convenient in Yunnan province than that in many other places, successful use of geothermal energy in life, often simple. But it brings several problems such as resources, or geothermal origin, or geothermal development management.In the general survey project of land and resources—1:50000 regional geological survey, Midu site, Xiangyun site, Weishan site and Juli site justly cover the whole Midu region. In this paper. we choose three hot springs such Jiashidong, Shizui and Jinlong spa in Midu. (E100°19'-E100°47', N 24°47'-N25°32').Yunnan. China. as our object, we study the base dates and analyze the regional geological background, geothermal distribution and occurrence characteristics of hydro geochemical characteristics, in article, we calculated temperature scale using SiO2, show the temperature and depth of thermal energy storage, and try to sum up the hot spring area in the terrestrial heat flow, tectonic, geological litho logy, and the formation model.From interaction related to water-rock, the hot spring water is rich in mineral composition, the study area, the largest anion is HCO3-, in hot spring water chemical composition, followed by SO42-or Cl-; most cations is Na+, followed by Ca2+, K+, Mg2+, the region chemical types are HCO3--Na+, springs are soft water with low salinity, and runoff areas of igneous rocks by the spring, showing some of the Cl" containing features.Geothermal heat storage structure is largely controlled from the research point of view, it is to take control of the three hot springs geothermal reservoir, in which, Jiashidong Spring and that of Shizui spa, and hot magma reservoir may be located in the fault zone had been frustrated Moving belt, and Jinlong Hot Springs geothermal reservoir can be in-Cenozoic sedimentary layer. And the temperature scale was calculated using chemical, and the temperature range of heat storage from93.5℃to 110.35℃, the temperature under the thermal energy storage and utilization of geothermal warming rate to estimate the deep circulation, by using isotope, supply source is atmospheric precipitation, and we estimated recharge elevation, which is located Midu Basin mountains, so that, hot springs area is a typical type of low temperature geothermal convective systems.A result of hot spring water containing silicic acid and F-ions and other chemical composition, if you have a bath every several days, possibly with certain medical effects on your health. from the test view, invovling water constituents, the springs in Midu are suitable for domestic and industrial use.
