摘要
本文讨论了新疆温泉县泥火山喷出水的化学特征。于2012年10月~2014年6月测量了温泉县泥火山喷发水、明目泉泉水及附近河水的化学组分(K+、Na+、Ca2+、Mg2+、F-、Cl-、SO2-4、HCO-3♂和CO2-3)和温泉县泥火山喷发水的氢氧同位素组成(δD和δ18O)。结果表明,该泥火山喷发水的化学类型为Na-HCO3SO4,δ18O-δD值小幅度偏离大气降水线,主要形成于大气降水顺断裂或裂隙深循环过程中与围岩的水岩作用;泥火山离子浓度较高,变化幅度低于5%,背景值稳定,可作为区域地震地球化学监测的对象。
Geochemical characteristics of water from mud volcano in the Wenquan County are discussed. Chemical characteristics( K+、Na+、Ca2 +、Mg2 +、F-、Cl-、SO2-4、HCO-3and CO2-3) of water samples from the mud volcanoes,Mingmu spring and river,isotopic contents( δD and δ18O) of water samples from the mud volcanoes are surveyed for four times from October 2012 to June 2014. Chemical type of water samples from the mud volcano is Na-HCO3SO4,which could be mainly derived from meteoric precipitation and affected by water-rock interaction. The values of δ18O and δD of water samples from the mud volcano are plotted along the meteoric water line with small shifts. Background values of chemical parameters of water from the mud volcano are stable,with the amplitudes of variation lower than 5%,indicated that the mud volcano could be an important object for geochemical monitoring of earthquake.
