湖北省地下热水成因类型及成矿模式分析

Genetic Type and Metallogenic Model of Geothemal Water in Hubei Province

湖北省地下热水资源较为丰富,多为低温地热资源。省内地下热水主要有隆起断裂型、沉降盆地型两种类型,分析其地下热水的特征、热储、热源、导热导水构造、排泄、形成机理等,在此基础上,将隆起断裂型分为变质岩式、岩浆岩式、背斜式、向斜式等四种成矿模式,将沉降盆地型分为裂隙孔隙式和裂隙岩溶式等两种成矿模式。

Geothemal water resources in Hubei province are abundant,which are mostly low temperature geothermal resources.Geothermal water in the study area is divided into two gentic types as lifted fault type and subsidence basin type.The characteristics,thermal storage,heat source,heat conduction and water conduction structure,discharge and formation mechanism of the two types of geothermal water are analyzed.On this basis,the uplift fault type can be divided into four metallogenic models:metamorphic rock type,magmatic rock type,anticline type and syncline type.The sedimentary basin type can be divided into two metallogenic models:fracture pore type and fracture karst type.
