江西法水温泉形成的基本特点及成因模式

Basic Characteristics and Formative Model of Fashui Hot Spring in Jiangxi Province

通过在法水热异常区开展地质、地球物理调查工作 ,分析了该区地下热水的分布规律和地质、地球物理特征。法水温泉的形成是多种因素综合作用的结果 ,热源主要来源于地壳深部。区内变质岩系与侵入岩体的接触界面是地下热水上升至地面的主要通道。建立了它的成因模型 ,这个模型不仅能够用于法水温泉的开发利用 。

Based on the geological and geophysical investigati on in geothermal anomaly area of Fashui hot spring,the distribution conditions o f underground thermal water and the geological\|geophysical characteristics in t he area are analyzed.The formation of the spring is owing to the composite effec ts of many factors.The resource of the heat mainly comes from deep crust,and the contact interface between metamorphic rock and intrusive mass is the main pathw ay where the underground thermal water rises to the ground.The formative model o f the spring is presented in the paper,which can not only be used to exploit and utilize Fashui hot spring,but also to guide the find of hot spring in Jiangxi a nd other similar regions.
