Based on the available data

25 geothermal heat flow data collected from Jiangxi were collected.The average heat flux measured in the whole province is 70.14 mW/m

2

slightly higher than the average value of global continental heat flow.According to the characteristics of heat flow value and combined with regional geological tectonic background could divided into three heat flow contrast zones-north Jiangxi

central Jiangxi

south Jiangxi.North Jiangxi and south Jiangxi in the Jiangnan orogenic belt and the Southern China orogenic belt

respectively

the measured surface heat flux averaged 58.0 mW/m

2

and 76.03 mW/m

2

respectively.central Jiangxi Including in the northeast of Jiangxi by

Cathaysian plate and Yangtze plate collision effect

experienced geological processes such as deposition

thrusting and magmatism

so it have high surface heat flow value 72.21 mW/m

2

.From north Jiangxi to south Jiangxi

the surface heat flow is more and more high.It is reflect of differences in rock composition

radiogenic heat

element content

crustal thickness

tectonic activity and lithospheric Thermal structure.
