【摘要】 本文以水文地球化学观点和方法,对冀中拗陷地热异常区深井网多井孔热水化学观测资料进行了计算处理。利用地热基础理论中的地球化学温标公式反演了拗陷内地温场基本特征和地热活动状况。指出地温场分布特征与地震活动在空间上有一定依存性,而地热动态变化与地震孕育在时间上似具有较好的同步性。最后,依此提出文安—坝县地震危险区的某些地球化学判据。更多还原

【Abstract】 In this paper,data of hydro-chemical observation obtained from deep wells in the geothermal anomaly area of Central Hebei Depression are analysed.The basic features of the geothermal field and the states of geothermal activity in the depression have been inversed by using the geochemical temperature scale formula.It is suggested that there existed certain correlations between the geothermal distribution and earthquake activity and between the geothermal variations and the seismogenesis. Some geochemical criteria for the Wenan-Baxian seismic risk area are proposed accordingly.更多还原
