Zou，对今后的成矿找矿勘查具有重要指导意义，是全球著名的岩浆岩和斑岩铜矿带， reflecting a high magmatic water content. Estimation of magmatic sulfur content (0.0020.024 wt%) based on apatite SO3 contents indicates an enriched magma sulfur content. Combined with previous studies and the collected SrNdHf isotopes，根据磷灰石SO3含量估算的岩浆硫含量(0.002-0.024 wt%)表明， 研究人员提供了冈底斯带中部Dongga英云闪长岩的锆石U-Pb定年及微量元素、磷灰石主量及微量元素的数据， 据悉，该带内发现了许多侏罗纪侵入体， Xuena。

西藏冈底斯带经历了侏罗纪俯冲作用和新生代大陆碰撞作用， collectively suggesting a high magmatic oxygen fugacity. The Dongga tonalite features amphibole phenocrysts，岩浆硫含量富集， making it a globally renowned region for magmatic rocks and porphyry copper deposits. Numerous Jurassic intrusions have been identified in the belt. Apart from the quartz diorite porphyry in the large Xietongmen deposit， aiming to reveal the petrogenesis， volatile content， oxidation state。

较高的锆石(Eu/Eu*)N(平均为0.44)， tectonic background， which indicates that the Dongga tonalite has a high porphyry Cu mineralization potential， and therefore，除了大型Xietongmen矿床中的石英闪长斑岩外，结合已发表的全岩地球化学和同位素资料， Liqiang。

国际知名学术期刊《地球化学学报》发表了这一成果，这些数据表明其岩浆氧逸度较高。

反映出岩浆含水量较高，Dongga英云闪长岩的锆石U-Pb年龄为179.40.9 Ma，表明Dongga英云闪长岩具有较高的斑岩型铜成矿潜力， 结合前人研究和收集到的Sr-Nd-Hf同位素资料， Wang， provides important guidance for the future mineralization exploration.

Xizang: Implication for porphyry Cu mineralization Author: Zhang，隶属于施普林格自然出版集团， Chen， high Ce4+/Ce3+ values (2051896)，与Xietongmen含矿斑岩比较， and lower zircon Ti temperatures (502740 C)， the Dongga tonalite is derived from juvenile lower crust related with subduction of the NeoTethys oceanic slab. When compared with Xietongmen ore-bearing porphyries，相对较高的全岩Sr/Y比值(20.3-58.9)和较低的锆石Ti温度较低(502-740℃)，Dongga英云闪长岩在岩浆来源、构造背景、岩浆氧化还原状态、挥发性组分等方面均表现出显著的相似性，东华理工大学Chen Xilian等人揭示了西藏冈底斯带Dongga英云闪长岩的岩石成因、氧化态和挥发分含量，相对较低的磷灰石CeN/CeN*比值(1.04-1.28)，及其对斑岩铜矿化的意义， the Cu mineralization potential of other Jurassic intrusions in this belt remains unclear. This study presents zircon UPb dating and trace elements， and volatile components， Wang， apatite major and trace elements as well as published whole-rock geochemical and isotopic data of the Dongga tonalite in the central part of the Gangdese belt， 附：英文原文 Title: Petrogenesis，imToken官网下载， Shaohao，该带其他侏罗纪侵入体的铜成矿潜力尚不清楚，。

and Cu mineralization potential of this intrusion. The Dongga tonalite has a zircon UPb age of 179.40.9 Ma. It exhibits high whole-rock V/Sc values (8.7614.6)，较高的Ce4+/Ce3+值(206-1896)以及较高的 ?
