摘要 

迄今我们习用的地壳化学元素丰度和岩石平均化学组成的文献值大多是收集的汇编数据,不少微量元素特别是贵金属等难测元素的丰度所依据的样品的代表性和测试质量难以考证,其值存在着颇大的不确定度。本研究立足于实测资料,在中国东部系统采集了各类火成岩和变质杂岩体及各时代的标准地层剖面岩石样品28253个,组合成2718个分析样。采用中子活化等15种可靠分析方法测试,以国家一级标准物质作质量监控。求得的华北地台地壳、中国东部上地壳和出露地壳及各类岩石的78种化学元素丰度,显著改善了地壳和岩石的化学元素丰度,填补了多种岩石微量元素丰度的空白。

Abstract

Element abundances of the continental crust and rocks cited in the past and recent literature have been based on compilations of data from various studies. This leads to uncertainties in sample representativeness and data quality. The present study is based on systematic collection of 28 253 individual rock samples over an area of 3.3 million km2 in eastern China, east of eastern longitude of 105°.The sampling involves more than 800 igneous intrusive bodies and metamorphic complexes as well as more than 500 type stratigraphic sections. From the individual rock samples, 2 718 composite samples were made and analyzed for 77 elements by 15 specific methods, dominantly XRF and INAA. Analytical quality was controlled by international and national preliminary geochemical reference materials of GSR, GAu and GPt series. Synthetic results from geological, geochemical and geophysical studies were used to construct crustal constitution model, from which element abundances of the continental crust in the North China platform, the upper crust and exposed crust in eastern China, chemical composition of igneous rock in China and of sedimentary rock and metamorphic rock in eastern China were derived.
