从汶川地震探讨隐爆与成矿过程
发布时间：2019-03-01 09:19
【摘要】：关于地震的成因机制目前还存在很大争议,2008年汶川大地震后的探槽、钻探和测井及地球物理勘探资料研究表明,汶川地震是一个从西南往东北方向渐进的隐爆过程。通过进一步对比国外地震的研究结果推测,地震的隐爆动力机制包含两个方面,其一是地下流体相变膨胀爆炸,其二是地下深处的累积负电荷放电(地下雷电)。然后通过对比斑岩矿床的成矿机制说明地震是一个压力温度释放过程,可以满足斑岩型矿床成矿的压力、温度、酸碱度等变化要素。本次地震富集了磷、硫、铁、锰等元素。这说明地震是一种由断裂运动激发引起的地下隐爆和成矿过程。
[Abstract]:There is still much controversy about the genesis mechanism of the earthquake. The research on the exploration trough, drilling, logging and geophysical exploration data after the Wenchuan earthquake in 2008 shows that the Wenchuan earthquake is a gradual hidden explosion process from the southwest to the northeast. By further comparing the research results of foreign earthquakes, it is deduced that the hidden explosion dynamic mechanism of the earthquake includes two aspects: one is the phase transition expansion explosion of underground fluid, and the other is the accumulated negative charge discharge (underground lightning) in the deep underground. By comparing the ore-forming mechanism of porphyry deposits, it is shown that the earthquake is a process of pressure-temperature release, which can satisfy the changing factors of ore-forming pressure, temperature, acidity and alkalinity of porphyry deposits. The earthquake enriched phosphorus, sulfur, iron, manganese and other elements. This indicates that the earthquake is a kind of underground implosion and mineralization process caused by the fault movement.
