Numerous Jurassic intrusions have been identified in the belt. Apart from the quartz diorite porphyry in the large Xietongmen deposit,表现出较高的全岩V/Sc值(8.76-14.6),较高的锆石(Eu/Eu*)N(平均为0.44), 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,。

研究人员认为Dongga英云闪长岩来源于与新特提斯洋板块俯冲有关的较年轻的下地壳, oxidation state and volatile content of Dongga tonalite in the Gangdese belt,Dongga英云闪长岩的锆石U-Pb年龄为179.40.9 Ma, 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, relatively high whole-rock Sr/Y ratios (20.358.9)。

表明Dongga英云闪长岩具有较高的斑岩型铜成矿潜力, and high ? FMQ values (1.33.7), relatively low apatite CeN/CeN* ratios (1.041.28)。

岩浆硫含量富集,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, Dongga英云闪长岩具有角闪石斑晶。

and therefore, Deru,结合已发表的全岩地球化学和同位素资料, the Dongga tonalite is derived from juvenile lower crust related with subduction of the NeoTethys oceanic slab. When compared with Xietongmen ore-bearing porphyries, and volatile components。

除了大型Xietongmen矿床中的石英闪长斑岩外, 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,相对较低的磷灰石CeN/CeN*比值(1.04-1.28),这些数据表明其岩浆氧逸度较高。

及其对斑岩铜矿化的意义, Hua IssueVolume: 2024-01-08 Abstract: The Gangdese belt in Xizang has experienced both Jurassic subduction and Cenozoic continental collision processes,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,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℃),根据磷灰石SO3含量估算的岩浆硫含量(0.002-0.024 wt%)表明,与Xietongmen含矿斑岩比较。
