1982年和1984年,作者等相继在西藏自治区昂仁县搭格架等地热田发现大面积含铯硅华,现作一简要报道。搭格架地热田是已知国内最大的间歇泉,其地质概况及其硅华沉积前人已有所报道。其有用组分包括固、液相两类。据该区多年地热水样分析结果比较,其水型按库尔洛夫式属重碳酸氯钠水,水中富含硼、锂、铯、硅等元素。尤其是热水中铯含量高于铷,其铯、铷值约等于8。 In 1982 and 1984, the authors successively found a large area of ​​cesium-containing silica in the geothermal field such as the Liaogeng shelf in the Tibet Autonomous Region. A brief report is now made. Ragged geothermal field is known as the largest geyser in China, its geological survey and its predecessor have been reported. The useful components include solid and liquid phases. According to the area for many years compared with the results of geothermal water samples, the water type by the Ku’erluofu is heavy sodium bicarbonate water, water is rich in boron, lithium, cesium, silicon and other elements. Especially in hot water cesium content higher than rubidium, cesium, rubidium value is about equal to 8.
