| 摘 要： | 大柴旦温泉沟泉水作为柴达木盆地出露的典型富矿水体,对于揭示柴达木盆地成盐、成矿至关重要。为了研究泉水的地球化学成因,开展了热泉水、冷泉水和八里沟河流水体的元素和氢氧同位素地球化学研究及其对比分析,并结合区域地质构造特征对其水体的来源、水文过程形成了较为细化的新认识:温泉沟的泉水来源于冰雪融水,而与雨水关系不大;八里沟水体相对富集B、Li,且具有类似于泉水的地球化学特征,推断其成因与断裂带密切相关。对于岩浆水与泉水的关系,需要进一步开展研究。

| Abstract: | :As typical water in Qaidam Basin which is rich in ore, the spring water in Da Qaidam is very benefical to reveal the formation of salt. In order to study the geochemical genesis of spring, the elementary composition,and hydrogen and oxygen isotopes ratio of hot spring, cold spring water and river water were tested. Base on the data and its comparative analysis, further more combine the regional tectonics, a more detailed new understanding was inferred aiming to the source of the water and its hydrological processes. The spring water origin is from ice and snow melting water instead of the rainwater.The water of Bali ditch is similar to the hot spring, which formation may be related to fault.Further researches are needed to elaborate the relationship between magmatic water and spring water. |
