The Relation Between the Geotemperature Distribution and the Geotectonics in China

Abstract

Geotemperature distribution in China is considered to be controlled by its geostructural framework and its positions in the global tectonics. It is well known that almost all high temperature geot.hermal regions correspond Hith modern faulting activities, modern volcanical act.ivitiesand recent IDaodffiatic movement, i.e. they are located on the edges of the lithospheric plates. Geothermal anomaly in China is one part of the global geothermal zone. It is affected by the motions of Eurasian plate, Indian plate; Pacific plate and Philippine sea plate. Such characteristics could be described by Fig.l. Two important geological documents in Asian continent during Cenozonic are specially considered: one is the collision between the" Indian plate and Eurasian plate, and the other is the collision between the Eurasian plate and Pacific plate. The former resulted in the geot.hermal anomalies in South-Western China, and the latter resulted in the anomalies in Eastern and South-East.ern China.
