藏东花岗岩全岩地球化学数据

野外调查发现左贡碧土地区的基性岩、超基性岩及其它混杂岩的岩石组合，表明构造混杂堆积的存在。主微量元素与Ｓｒ－Ｎｄ同位素均在中国科学院地球化学研究所矿床地球化学重点实验室完成。其中主量元素采用ＰＷ４４００型Ｘ荧光仪全岩分析，测定１０种元素氧化物含量；微量元素采用ＩＣＰ－ＭＳ电感耦合等离子体质谱分析仪进行测试，ＩＣＰ－ＭＳ由日本东京安捷伦公司制造，型号为Ａｇｉｌｅｎｔ　７７００ｘ，分析方法同张鑫等。根据对标准样品ＧＢＰＣ－１ｄｅ分析结果，分析误差＜５％。实验检测依据为ＧＢ／Ｔ　１７６７２—１９９９。

Field investigations revealed the rock assemblages of mafic rocks, ultramafic rocks and other mélanges in the Bitu area of Zuogong, indicating the presence of tectonic mélange deposits. Major and trace element compositions as well as Sr-Nd isotopic analyses were all conducted at the Key Laboratory of Ore Deposit Geochemistry, Institute of Geochemistry, Chinese Academy of Sciences. Specifically, major elements were analyzed via whole-rock analysis using a PW4400 X-ray fluorescence spectrometer, with the contents of 10 element oxides determined. Trace elements were tested using an inductively coupled plasma mass spectrometer (ICP-MS), which was manufactured by Agilent Technologies in Tokyo, Japan, with the model Agilent 7700x. The analytical method followed that of Zhang et al. Based on the analytical results of the certified reference material GBPC-1de, the analytical error was less than 5%. The experimental testing was conducted in accordance with GB/T 17672—1999.
