同位素地球化学方法与地震研究及地震预报

通过在地震活动区对有关地质体的K—Ar、Ar—Ar、FT、TL、~(14)C、ESR、U系等同位素年代学、地下水及其释放气体的D/H、~(13)C/~(12)C、~(18)O/~(16)O等稳定同位素以及He、Ar等稀有气体同位素的研究,可获得有关新构造运动的时间序列、断层运动的时间、地质体热历史以及地下断层流体运动的许多重要信息。因而,同位素地球化学已逐渐在研究地震成因机制以及监测预报地震中发挥重要作用。

THE ISOTOPIC GEOCHEMISTRY TECHNIQUEAND THE SEISMOLOGICAL RESEARCHAND EARTHQUAKE PREDICTION

Studying at the quake-active area on the isotopic chronology of K-Ar, Ar-Ar, FT, FL, 14C, ESR, U series of the relating geological body, the underground water and the stable isotopes of D/H, 13C/12C, 18O/18O by its released gases, and the isotopes of the rare gases of He and Ar, we can obtain many important informations concerning the time sequence of the neotectonic movement, the time of the fault movement, the thermal history of the geological body and the fluid movement of underground fault. Therefore we can find that the isotopic geochemistry is gradually playing an important role in studying the seismic formation mechanism and in seismic monitoring and prediction.
