摘要
以铜鼓县温汤温泉和古桥汤里温泉为例,探讨了其水文地球特征。通过建立在水-岩平衡基础上的地热温标方法,对其热出温度做出评价。并通过对其地质背景研究,分析其温泉成因。经研究表明修水白岭抗日温泉水化学类型为HCO3-Na型水、铜鼓温汤和汤里温泉属于SO4-HCO3-Na-K型水,这与两地所处地质背景条件不同有很大关系。此外,通过多矿物平衡图解和Na-K-Mg三角图解模拟分析,得知三处温泉皆未达到水-岩平衡,只有抗日温泉1号孔接近水-岩平衡状态,并由此估算其热储温度为100~120℃,和用Si O2温标计算值102~125℃比较吻合。
The Tonggu Wentang hot springs and the Guqiao Tangli hot springs are discussed about the hydrological characteristics. The hot temperature is evaluated by the geothermometer methods based on the water-rock equilibrium. And analyzes the factor of hot springs through the research on the geological background. The results showed that hydrochemical types of Xiushui Kangri hot spring thermal waters are the type of HCO3-Na, and Tonggu Wentang and Tangli hot spring thermal waters are type of SO4-HCO3-Na-K that caused by the different geological background conditions. Besides, all the three hot springs are inferior to balance of water-rock by the mineral balance diagram and the Na-K-Mg triangle graphic simulation. Only the No.1 drill from Kangri hot spring is close to the balance of water-rock, and the reservoir temperature is estimated to be 100-120%℃ that is consistent with the 102-102 ℃ which calculated by the geothermometers of SiO 2.
