Source tracing elements of K-feldspars of main rivers around Bohai Bay Basin

摘要: 渤海湾盆地碎屑物质的物源示踪研究，对于渤海湾盆地的自身演化，周缘造山带隆升和剥蚀过程，以及中国东部陆架海的物质扩散研究均具有重要意义，受到国内外学者的广泛关注，同时也存在诸多争议。钾长石是地壳中最主要的造岩矿物之一，在河流沉积物中广泛出现，在进行物源示踪研究时具有代表性。基于此，利用激光剥蚀电感耦合等离子质谱仪（LA-ICP-MS）对渤海湾盆地主要注入河流的碎屑钾长石进行了原位地球化学特征分析，结果表明，黄河干流碎屑钾长石的常量元素Na2O、Al2O3、SiO2、K2O的标准偏差与滹沱河、滦河、辽河和漳河4条河流存在差异。在钾长石常量元素Al2O3质量分数与Na2O和K2O质量分数二维散点图中，部分黄河样品的Al2O3值较之整体部分（其他4条河流和黄河样品）偏低；微量元素中Ba、Pb、Sr、Rb和Ca的质量分数占主体部分，尤其Ba、Pb、Sr、Rb的含量较高。在Ba和Sr以及Ba和Pb质量分数二维散点图中，黄河与其他4条河流明显不同。该研究结果表明，钾长石的Ba和Sr含量变化可以成为环渤海湾盆地沉积物中黄河物源示踪的特征指标。Abstract: The study on provenance identification of Bohai Bay Basin is great significance to its evolution, the uplift and erosion process of the peripheral orogenic belt, and the material diffusion of the continental shelf sea in eastern China.K-feldspar is one of the most important petrogenic minerals in the earth's crust, which is widely found in the river sediments, being representative in the study of source tracing.After long-distance river transportation, its element characteristics can still well record the information of its source area.Based on these facts, in this study, we rely on the laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to analyze the geochemical index from the river detrital K-feldspar of the Bohai Bay Basin.The results show that the contents of Na2O, Al2O3, SiO2, K2O of K-feldspar grains from the Yellow River are significantly different from the Hutuohe River, Luanhe River, Liaohe River and Zhanghe River.In the two-dimensional scatter diagram of Al2O3, Na2O and K2O, the Al2O3 value of some Yellow River samples is lower than the others.The contents of Ba, Pb, Sr, Rb and Ca are the main parts of trace elements, especially the first four.In the two-dimensional scatter diagrams of Ba and Sr and Ba and Pb, the Yellow River is obviously different from the other four rivers, which makes it a characteristic river in the study of provenance tracing in the Bohai Bay Basin.
