| 石阡地区具有丰富的地热资源，在石阡-花桥断裂带及其次级构造中形成了一系列的温泉群。断裂构造对地热资源具有严格的控制作用。本文通过对石阡-花桥断裂带显微构造、运动学等构造地质特征和该地区地热特征，系统分析石阡-花桥断裂带构造特征及其对地热资源的控制作用。研究认为，石阡地区地热资源的主要热源为地温梯度增温，地热资源的分布严格受控于石阡-花桥断裂。石阡断裂为逆冲兼左行平移断层，为地热水的传导和储集提供了有利空间。花桥断裂带发育拉张裂隙、扭裂隙及分枝状断层，圈闭了含水岩系，在拉裂破碎带上形成热储。温泉大多沿主要控热、导热断裂出露，平面上呈线状分布于石阡和花桥断裂上盘及花桥断裂的断夹块中。 |

| Shiqian area has abundant hydrothermal resource. Series of hot spring group formed in Shiqian-Huaqiao fault zone and its secondary structure. The fault structure has strict control function for hydrothermal resource. In this paper，as the microstructure，kinematics and other structural geologic characteristics of Shiqian-Huaqiao fault zone and the hydrothermal features in this area，the structural characteristics and its control function of Shiqian-Huaqiao fault zone are analyzed systematacially. The study shows：the major heat source of hydrothermal resource in Shiqian area is geothermal gradient temperature increasing，the hydrothermcal resource is controlled strictly by Shiqian-Huaqiao fault zone. Shiqian fault zone is thrust and left strike-slip fault，it affords advanced space for transition and storage of geothermal water. Huaqiao fault zone developed and pulled fracture，twist fracture and dendroid fault，then close the water-bearing rock series，finally formed heat reservoir in crack fracture zone. The hot spring mainly emergence along the heat-control fault and heat conduction fault，distribute as line in fault granular of Shiqian，up Huaqiao fault and Huaqiao fault. |
