Abstract

Abstract

The geotherm of ore-forming fluid affects ore formation directly. This article studies the effect of annual precipitation on the geotherm of ore-forming fluid, according to the geohydrologic conditions of the central Hunan basin. Ore-forming fluid in antimony deposits in Xikuangshan was taken as an example and a representative section of Xikuangshan-Yuepingfeng was chosen. Heat and gravity driven modes of fluid movement were considered. A contrastive rainfall Q=1 200 mm/a was chosen, the distribution of the area temperature field was calculated, and the difference of two temperature fields was obtained by taking the annual precipitation of 600 mm/a, 1 800 mm/a and 2 400 mm/a compared with the temperature field of the contrastive rainfall. The simulation result shows that precipitation affects the fluid field more than the temperature field. The effect of precipitation on the temperature stays between 5%-20%. The effect of precipitation on the geotherm of ore-forming fluid is negligible.
