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。
Dachaidam Wenquangou spring water as a typical Qaidam basin rich mineral water, revealing the Qaidam Basin salt formation, mineralization is crucial. In order to study the geochemical cause of spring water, the elemental and hydrogen-oxygen isotopic geochemical studies and comparative analyzes of hot spring water, cold spring water and Baliu River water bodies were carried out and their source and hydrological processes were formed according to the regional geological tectonics The new understanding is more detailed: the spring water of Wenquangou comes from melting of ice and snow, and has little to do with rainfall; the water body of Baliu ditch is relatively enriched in B and Li, and has the geochemical characteristics similar to spring water, and deduces its origin and fault zone closely related. For the relationship between magmatic water and spring water, further research is needed.
