摘要
依据粘土中微量元素硼含量,硼/镓比或应用硼—镓关系图划分海相、陆相的实际工作中已暴露颇多矛盾。作者对我国西部第三系陆相含盐沉积与现代盐湖底质泥样含硼量和硼/稼比的研究,也证明了这个指标不能区分海相与盐湖相、并认为应用该指标会影响到中国第三纪海侵研究的准确性。根据我国青藏高原盐湖及温泉含硼量研究的新成果,从机理上说明了为什么许多盐湖含硼量显著高于海洋的原因。
Many contradictions have been observed when the boron content or the B/Ga ratio in clay mineral, or the graph showing the relationship between boron and gallium is applied to differentiate the marine facies from the continental facies. By analyzing the boron content in the saline formation in the Tertiary Continental facies in the west part of China and that from the bottom of mud slurry samples in a modern salt lake, as well as the B/Ga ratio calculated, it is demonstrated that this indicator can not differentiate the marine facies from the inland salt lake facies. The reliability of the study of the marine transgression in the Tertiary forma-tion in China by using this indicator is questionable. According to the results of the studies of the boron contents in the salt lakes and the hot springs in Qinghai-Tibet Plateau, the question, why the boron content of many salt lakes are much higher than that of marine facies, is explained.
