摘要
近年来对福建省存在具有岩浆热源的高温水热系统的呼声甚高。因而在福建是否可能存在具有岩浆热源的高温热田再次成为必须回答的重要问题。在综述前人研究成果的基础上,论述了福建省地热活动的地质构造背景、温泉分布状况、地热系统的特征、深部是否存在岩浆热源以及地壳的热结构,系统论述了福建深循环水热系统的特征。认为由于地质构造条件所决定,福建有大量的温泉出露,其中大部分为中温水热系统(90～150℃)和低温水热系统(<90℃),均属受断裂控制的深循环水热系统,皆为温水热储。极少数高温热水系统(>150℃)也仅仅是地下水沿断裂循环的深度较大所致。笔者认为福建不具备形成"有岩浆热源的水热对流系统"的条件。
In recent years,the voice that Fujian has high-temperature geothermal systems with magmatic heat source is very high.So it is a must to answer the important question.The author reviews the researched achievements of predecessors and discusses following topics： the geological setting of geothermal activity in Fujian,distribution of thermal springs,types of geothermal systems,magmatic heat source in the depth and heat structure of crust in this paper.According to the setting of geological tectonics in Fujian Province,a large number of medium-temperature（90-150 ℃） and low-temperature（90 ℃） hydrothermal systems are controlled by faults and become the warm water reservoir by means of deep circulation.The limited hot water systems with higher temperature（150 ℃）formed through deep circulation in the depths of earth crust.The author thinks that Fujian Province does not have the tectonic setting to form hydrothermal systems with magmatic heat sources.
