摘要
从岩层的化学组成和矿物结构方面讨论了地壳内含量较多的花岗岩层对地震孕育的作用 ,通过理论探讨与实际震例结合 ,分析了孕震过程中可能发生的各种化学变化 ,指出花岗岩层中水文地球化学指标的映震能力很大程度上取决于岩石中 [AlO4 ]含量的多少。
This paper discussed the effect on source process from rock stratum with more granite in the crust with the information about the chemical composition of the rock and mineral structure. Through theoretical study and practical earthquake examples, we analyzed various chemical reaction that may happen during the earthquake preparation and pointed out that the ability reflecting the earthquake through the hydrogeochemical index is depended on the amount of the AlO 4 in the rock formation in a great degree
