| 摘 要： | 啦井温泉喷流沉积物中富集了Mn、Zn、Sr、Ba及其他元素,作者首次发现其已构成多金属矿化体,为此进行了详细的地球化学研究。温泉属硫酸盐型弱酸性水,C、H、O同位素表明,温泉成因于循环大气降水。从沉积特征分析,温泉经历了爆发喷流期与渗流期的演化过程。

| Abstract: | The spurting fluid deposits of the Lajing hot spring, Lanping, Yunnan, are richin Mn, Zn, Sr, Ba and other valuable elements. A polymetallic mineralized bodycontaining these elements was for the first time discovered In the deposits by theauthors. Intensive geochemical study shows that the water of the hot spring isweakly acid water of sulfate type. C, H and O isotope studies indicate that the hotspring originated from circulating meteoric water. Analysis of sedimentary featuressuggest that the hot spring has gone through a process of evolution from the explo-sion and fluid spurting stage to the permeation stage. |
