| Abstract |
Based on the distribution of hot springs and carbonated springs already known along the southeast coast of China, this paper deals with the arrangement and origin of these hot spring, and presents a model of "produced heat by deformation of crustal layering". According to data on chemistry of the springs and calculations on the balance between water and minerals in the geothermal reservoir, the author suggests that certain materials, including the products of mantle origin and metamorphism at depth, may escape into the geothermal systems, and that the regional metamorphism of zeolite facies is developing along the coastal area of southeast China. |
