以预测地震为目的地的震前各种征兆,从古代就着手研究了。直至最近几年用地球化学方法作为前兆现象来预测地震才引起了人们的兴趣。对地震危险区特征的了解以及预测未来地震的发生除了当前常用的一些方法之外,探索另外的方法或许是有所裨益的。对渡口市区主要部份面积约670Km~2的范围内采取了各类岩石标本500块,所代表的时代从前震旦纪的变质岩到震旦纪、古生代、中生代及新生代的沉积岩和岩浆岩等。采取的岩样
To predict the earthquake before the earthquake a variety of signs, from the ancient study. It is only in recent years that geochemical prediction of earthquakes has aroused people’s interest. Understanding the characteristics of a seismic hazard zone and predicting the occurrence of future earthquakes In addition to some of the more commonly used methods today, it may be useful to explore additional methods. In the main part of the ferry area of about 670Km ~ 2 within the scope of taking various types of rock specimens 500, representing the era of the former Sinian metamorphic rocks to the Sinian, Paleozoic, Mesozoic and Cenozoic sedimentary rocks and magma Rock and so on. Rock samples taken
