| 摘 要： | 热穹隆构造是在一个构造活动（逆冲）带中，由沿走向发生的地壳差异性升降运动（走向波浪机制）产生的构造穹隆中的热（液）活动事件，或是在这些部位由于中浅成岩浆岩的底辟式侵入而产生的热力性穹隆构造，它对金矿成矿的控制机理主要体现在适宜的浅层构造空间，贯深性构造通道及深源（下地壳）的岩浆源和矿质热液源的有机统一，主要的容矿空间为穹隆构造所产生的放射状（或束状）及环状构造裂隙系统。

| Abstract: | Thermal dome structure,which occures in an
active tectonic belt,is formed along strike by differential elevation-subsidence movement of
crust,or results from diapiric intrusion of middle-hypabassal magmatic rocks.With the
unification of its favorable shallow structural space,deep structural channel,deep-seated
magma reservoir and mineral hydrothermal source,the thermal dome structure embodies its
control mechanism over gold deposits.Radial (or sheaf) and circular fissures created by the
thermal dome structure are the main host space. |

| Keywords: | Active tectonic belt Thermal dome structure Gold deposit prediction |
