中国东北中生代斑岩铜钼和钼矿床成矿岩体及副矿物数据集

本数据为东北地区斑岩铜钼和斑岩钼矿中成矿岩体全岩主微量地球化学数据，副矿物磷灰石主微量和原位Nd同位素数据以及锆石微量和原位Hf同位素数据。样品采集自于东北地区燕山期斑岩铜钼和钼矿床中的成矿岩体。岩石全岩主微量地球化学数据是通过X荧光光谱仪和电感耦合等离子体质谱仪分析获得。矿物主微量地球化学数据是通过电子探针和激光剥蚀-电感耦合等离子体质谱仪分析获得。矿物原位Sr-Nd-Hf同位素地球化学数据是通过多接收激光剥蚀-电感耦合等离子体质谱仪分析获得。通过磷灰石和锆石的地球化学特征，限定了东北燕山期斑岩铜钼矿床与斑岩钼矿床成矿岩浆性质的差异。其中斑岩Cu-Mo矿床形成受控于俯冲板片浅部脱水形成的富Cl流体，它与板片俯冲直接相关；斑岩Mo矿床主要受控于下地壳含水矿物脱水形成的富F流体，受俯冲板片远距离效应影响。

This dataset contains whole-rock major and trace elemental geochemical data of ore-forming intrusions from porphyry Cu-Mo and porphyry Mo deposits in Northeast China, as well as major and trace elemental data and in-situ Nd isotopic data of the accessory mineral apatite, and trace elemental data and in-situ Hf isotopic data of zircon. All samples were collected from ore-forming intrusions associated with Yanshanian porphyry Cu-Mo and Mo deposits in Northeast China. Whole-rock major and trace elemental geochemical data were analyzed using X-ray fluorescence spectrometry (XRF) and inductively coupled plasma mass spectrometry (ICP-MS). Major and trace elemental geochemical data of minerals were analyzed using electron probe microanalysis (EPMA) and laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS). In-situ Sr-Nd-Hf isotopic geochemical data of minerals were analyzed using multi-collector laser ablation-inductively coupled plasma mass spectrometry (MC-LA-ICP-MS). The geochemical characteristics of apatite and zircon were used to constrain the differences in ore-forming magmatic properties between Yanshanian porphyry Cu-Mo deposits and porphyry Mo deposits in Northeast China. Specifically, the formation of porphyry Cu-Mo deposits is controlled by Cl-rich fluids generated by shallow dehydration of the subducting slab, which is directly related to slab subduction; while porphyry Mo deposits are mainly controlled by F-rich fluids generated by dehydration of hydrous minerals in the lower crust, and are affected by the far-field effects of the subducting slab.
