我队所勘探的矿区系汞矿。由于汞矿的成因与構造断裂有密切的关系,因而岩层的变化很复杂。断裂发宵的岩层其物理性質一般比較脆,如白云岩矽化后,经过構造断裂,产出較多的裂隙,经热充填或膠結作用后,則形成很发育的角礫化及节理,为矿液造成良好的通路。成矿后,岩石又经常受到节理切割,縱横交錯。而汞矿的产出必须有二次破碎,因而它的特点是舍矿愈富的岩层,則愈破碎,裂隙愈多,矽化亦愈强.如鑽孔摆在断层上或鑽遇断层,由于鑽进中所产生的廻轉力与压力的影响,岩心逐漸破碎,甚至成豆 The mine explored by our team is a mercury mine. Since the formation of mercury deposits is closely related to tectonic fracture, the change of rock formation is very complicated. After the fracture, the physical properties of rock formations are generally relatively brittle. For example, dolomite is silicified, and after structural fracturing, more fractures are produced. After thermal filling or cementation, well-developed brecciated and jointed formations are formed. Liquid causes good access. After mineralization, the rock is often cut by joints and criss-crossed. However, the output of mercury mine must be secondarily crushed, so that it is characterized by the fact that the richer the bedrocks are, the more broken the fissures are and the more silicified the crust is. Drilling into the resulting turbulence and pressure, the core gradually broken, and even into beans
