摘　　要：赤峰热水镇地热田内发育有南北向、北西—南东向、北东—南西向及东西向断裂构造,这些断裂大部分为张性断裂,并构成地热田热水上升的主要通道。热水的补给区在远离地热田的西部和北部山区,天水从此处渗透到地下深处,缓慢流动到地热田下部,被侵入的花岗岩和玄武岩所构成的热源以热传导方式加热,再沿断裂、裂隙上升,形成了地热田浅部热水储集层。本地热田热水属于天水起源的中、低温裂隙水。There are NS,NW-SE,NE-SW and WE direction faults developed in Reshuizhen geothermal field,and most of them are tensional faults forming the main channels for hot water growing up.The recharge area of the hot water is the western and northern mountainous areas away from the geothermal field to west and north where the precipitation permeated into the ground and flowed to the lower part of the geothermal field.The water was heated by invaded granite and basalt rocks by means of heat conduction,and then went along with the fractures,forming a shallow water reservoir of geothermal field.The geothermal field water belongs to mid-low temperature fracture water originated from precipitation.
