摘    要:概述了硫化物监测点的水地质及硫化物的来源和存在形式,并结合近二十多年的震例,分析和总结了硫化物的映震特征。表明硫化物的地震前兆异常基本上都是正异常,且具有一定的重复性,即硫化物测值遵循背景值-趋势性上升(或突升)-最高值-趋势性下降(或突降)-恢复至背景值,而地震常常发生在硫化物由高变低(靠近背景值)的过程中。并对硫化物异常形成原因进行了探讨,认为硫化物在生成过程中明显受孔隙压力(压强)的影响,这也是硫化物具有一定映震特征的主要原因。

关 键 词:硫化物  映震机理  地震前兆  地下水  地震预测  孔隙压力

Abstract:This paper described the hydrogeological characteristics of the monitored spring sites, the origin and existent form of their sulfides. Combined the earthquakes cased in the past more than 20 years, the earthquake reflecting features are analyzed and summarized. The results indicate that the earthquake precursor anomaly of the sulfides is usually normal, which shows a certain repeated property. That is, the change of sulfide values is as follows: background value-trend rise (or sudden rise)-trend drop (or sudden drop)-recovered to the background value. Usually the earthquakes occurred in the stage when sulfide values changed from the higher value to the low value (close to the background one). In this paper, the authors also discussed the origin of anomaly and concluded that the evident effect of pore pressure (pressure intensity) on the generation of sulfides is the major origin of sulfides having a certain earthquake reflecting features.
Keywords:Sulfide  Earthquake  reflecting mechanism  Earthquake precursor  Xinjiang Uygur Autonomous Region
