Characteristics of thermophysical parameters in the Wugongshan area of South China and their insights for geothermal genesis

The Wugongshan area is rich in medium–low temperature convective geothermal resources, among which there are more than 10 fields Wentang, Wanlongshan, Wenjia, Hongjiang, etc. There few basic geological studies the and their peripheral areas; thus far, no systematic research work into thermophysical parameters has been carried out. In this paper, 85 rock samples were collected from surface boreholes covering strata magmatic rocks study area. results show that average radioheat generation rate, thermal conductivity, specific heat 0.24–5.49 (μW/m 3 ), 1.995–4.390 (W/mK), 1.318–4.829 (MJ/m K), respectively. diffusivity ranges 1.115 to 1.611 × -6 m 2 /s. highest rate Jurassic granite, lowest quartz vein. largest conductivity siliceous quartzite, smallest Cambrian metamorphic mica schist, quartzite. radioactive heat, closely related chemical composition, mineral fabric, porosity, water content, pressure conditions of whole a linear relationship between (K) (κ), correlation equation K = −0.3144k + 3.2172. Combined with characteristics parameters, genetic theory deep crust structural accumulation quartzite conduction granite preservation preliminarily proposed.
