成矿裂隙(简称矿裂)和自然界其他事物一样,有它自己发生、发展以至消亡的历史。矿裂与无脉体充填的断裂构造区别在于:它直接表现出来的是矿脉(或岩脉)。矿裂的发展过程可分为三个阶段:成生阶段、张开充填阶段和破坏阶段,各阶段的应力状况和表现形式可以不同。与成矿密切有关的是成生阶段和张开充填阶段(图4),这两个阶段常交 Mineralization fissures (mineral spalling), like other things in nature, have their own history of occurrence, development and demise. The difference between the fractures and the veinless fault filling structures lies in the fact that the ore vein (or dykes) is directly manifested. The development process of mineral cracking can be divided into three stages: the formation stage, the open filling stage and the destruction stage. The stress states and manifestations in each stage can be different. Closely related to the mineralization is the growth stage and open filling stage (Figure 4), these two stages often pay
