红格地热水资源找矿前景分析

Genetic Mechanism and Prospecting For Geothermal Water Resources in Hongge

通过对昔格达断裂带和箐门口断裂带附近施工的勘查井地下水水量、气味、水温分析,认为带硫磺味的地下热水赋存在于箐门口断裂带附近的华力西期-印支期的岩浆岩和前震旦系会理群变质岩地段。昔格达断裂上盘为震旦系灰岩,白云岩互层,有丰富地下水,但昔格达断裂带构造运动的热能量交换不能满足所有地下水温度大幅加温的热能量,因此热能有可能还有来自地壳更深处的岩浆,而昔格达断裂则是热源的通道。

Geothermal water in Hongge occurs in metamorphic rock of the Pre-Sinian Huili Group and Hercynian-Indo-Sinian magmatic rock nearby the Qingmenkou fracture zone on the basis of the data on underground water from exploration wells nearby the Xigeda and Qingmenkou fracture zones. Sinian alternating beds of limestone with dolomite consisting of hanging wall of the Xigeda fracture zone are rich in underground water. All of thermal energy can come from both the Xigeda fracture zone and deep magma. The Xigeda fracture zone may be tunnel of thermal source.
