| 摘 要： | 前人对秦岭北缘断裂带出露温泉水的氢氧同位素、He同位素和SiO2含量进行了计算,得到了温泉水的热储温度和循环深度。在此基础上,运用温度场作用下的热水垂向运移数学模型演算了循环深度和断层带渗透性之间的关系。根据1970～2008年的区域台网资料,对断裂带进行了分段地震活动多参数组合方法分析,并结合历史中强地震(公元前781年～公元2008年)的空间分布特点,分析总结了断层带不同区段渗透特征和地震活动的关系。最后对秦岭北缘断裂带的渗透性成因进行了解释。

| Abstract: | On the basis of the heat reservoir temperature and the circulation depth of the hot springs evaluated by the predecessor's through hydrogen and oxygen stable isotopic composition,helium isotopic composition and silicon dioxide content of the water of the hot springs in the Northern Margin Fault Zone of Qinling,and using a mathematical model of vertical liquid movement affected by the geothermal field,we deduce a relation between permeability of the Fault Zone and circulation depth of the hot spring water.We... |
