为了解大吉山钨矿控矿断裂系统发展演化的复杂性,对采自江西省全南县大吉山钨矿不同深度的样品进行岩石声发射实验,表明岩石声发射事件序列特征明显,一般经历发生、平静和突发3个过程;矿区断裂系统的发生与发展演化具有崩塌-间断平衡的分形谱系结构,是极不连续的,其断裂过程的能量释放也是不连续的,随深度增加而变小,反映成矿作用发展过程。运用复杂性理论研究认为,断裂系统的发生与发展和成矿系统的演化具有相似的动力学特征,通过随机行为耦合而发生自组织、系统之间相互作用产生相干行为,进而达到协同同步化,跨越临界转变点,走向自组织临界性,二者均为成矿物质运动与时间、空间三者耦合与相互作用的结果。大吉山脉状钨矿的形成与控矿断裂系统的临界破裂及其串级崩塌-间歇平衡的分形生长有着紧密的联系,即大吉山脉状钨矿床成矿模式遵循广义的“五层楼”成矿模式。
In order to understand the complexity of the evolution and development of the Dajiashan tungsten ore control and fracture system, rock acoustic emission experiments were carried out on samples collected from different depths of the Dajishan tungsten deposit in Quannan County, Jiangxi Province, indicating that the sequence of rock acoustic emission events is obvious and generally experienced , Calmness and suddenness. The occurrence and evolution of the fault system in the mining area have the fractal-lineage structure of collapse-discontinuity balance, which is extremely discontinuous. The energy release in the fracture process is also discontinuous and decreases with increasing depth , Reflecting the development of mineralization process. Based on the complexity theory, it is considered that the occurrence and development of fault system and the evolution of metallogenic system have similar dynamic characteristics. Self-organization occurs through the coupling of stochastic behavior and the interaction among systems produces coherent behavior, Crossing the critical transition point to self-organized criticality, both of which are the result of the coupling and interaction of the movement of mineralization with time and space. The formation of the Daji Mountain Tungsten Deposit is closely related to the critical rupture of the ore-controlling fracture system and its cascade collapse-intermittent equilibrium fractal growth. The metallogenic model of the Daji Mountain vein-like tungsten deposit follows the generalized “five-story” Metallogenic model.
