從汶川地震探討隱爆與成礦過程

【摘要】:關(guān)于地震的成因機制目前還存在很大爭議,2008年汶川大地震后的探槽、鉆探和測井及地球物理勘探資料研究表明,汶川地震是一個從西南往東北方向漸進的隱爆過程。通過進一步對比國外地震的研究結(jié)果推測,地震的隱爆動力機制包含兩個方面,其一是地下流體相變膨脹爆炸,其二是地下深處的累積負電荷放電(地下雷電)。然后通過對比斑巖礦床的成礦機制說明地震是一個壓力溫度釋放過程,可以滿足斑巖型礦床成礦的壓力、溫度、酸堿度等變化要素。本次地震富集了磷、硫、鐵、錳等元素。這說明地震是一種由斷裂運動激發(fā)引起的地下隱爆和成礦過程。
[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.
