摘要
曹畈地热田位于湖北省的浠水县与罗田县交界的曹畈村—许家冲村一带,温泉主要出露在义水河支流界河河漫滩。地热田具体构造部位位于方家冲北东向倒转背斜南东翼倾伏端,地热田构造格局主要受控于北东向和南北向两个方向上的构造应力,地热田构造以断裂为主,属断裂构造型地热田。从地热地质条件、地热流体化学特征、热源、热储、热储盖层及地下热水补径排条件对地热田成因进行初步分析,并尝试建立地热田成因模型。
Caofan geothermal field is located at Caofan village-Xujiachong village in the junction of Xishui county and Luotian county,hot springs are mainly exposed in flood plain of boundary river of Yishui river tributary.The specific structure of geothermal field is located in the dipping end of the southeast wing of Fangjiachong reverse anticline in the NE trending structural belt,influenced by NE trending structural belt and NS structural stress,the structure of geothermal field is dominated by faults,belongs to fracture structure geothermal field.In this paper,based on the geological conditions,chemical characteristics of geothermal fluid,heat source,thermal reservoir,thermal reservoir caprock and supplement,runoff,discharge condition of geothermal water,the authors preliminarily analyze the genesis of geothermal field and try to establish the genetic model of geothermal field.
