    Application of Fixed-Al Modified log(Q/K) Graph in Hot Spring System

    • 摘要: 为探讨常规和固定铝log (Q/K) 图解法对温泉系统是否有效, 采用WATCH程序, 对江西3个温度较高的温泉, 即庐山温泉、汤湖温泉和横泾温泉, 进行了探测性的研究.采用常规log (Q/K) 图解法计算时, 由于参加计算的4个水样的铝含量均未检出, 计算结果显示只有不含铝的矿物玉髓和方解石相交于温度1 0 0℃附近, 热储总体上没有达到平衡.在采用了固定铝log (Q/K) 图解法并同时考虑冷水的稀释作用计算后, 中低温地热系统中常见的蚀变矿物如浊沸石、纤蛇纹石、萤石和玉髓均显示了较好的收敛性, 收敛的温度大致在1 0 0~ 1 4 0℃.并且上述矿物组合可见于某些温泉的深部钻孔中, 计算结果与实际地质情况相吻合.结果表明固定铝log (Q/K) 图解法可以恢复温泉系统的热平衡状态
