摘要
新疆苏约克泉华位于地震高发的断裂带上,是研究地震信息的良好载体。通过U-Th定年标定时间,利用地震烈度信息和泉华中δ^(13)C、微量元素和常量元素进行比对用于研究地震在泉华沉积中的记录,结果表明不相容元素对地震烈度反映不明显,δ^(13)C(r=0.979)和MgO(r=1)含量与地震烈度具有正相关关系,Zn(r=-0.692)元素含量变化与地震烈度成负相关关系,以上三种地球化学指标可用与恢复地震信息。研究结果不仅表明苏约克泉华的内生热成因,而且也提供了一种提取区域地壳活动信息的方法,也为甄别区域古代有争议是否发生的地震提供了方法依据。
Sulyok sinter is located at seismic fault zone which can be used to research seismic information. The time of sinter are calibrated by U-Th dating. δ^(13)C,trace elements and major elements in sinter are contrasted with seismic intensity to find the relations of them. It is reported that incompatible elements reflect little on the seismic intensity,and δ^(13)C and MgO have positive correlation with seismic intensity,with r = 0. 979 and r = 1 respectively.Zn content is negtive correlation with seismic intensity with r =- 0. 692. Three of them can be used to retrive the past seismic information. The results show that the Sulyok sinter is inner thermal genesis,additionally,a new approach to retrive the past seismic have been proposed,this approach hence can be used for confirming whether or not the seismic is occured.
