    摘要

  • 与镁铁–超镁铁质岩体相关的岩浆矿床，包括硫化物和氧化物矿床，是Ni-Cu-PGE和Fe-V-Ti矿床的重要类型。峨眉山大火成岩省以发育众多此类侵入体及其相关的岩浆Ni-Cu-PGE-Fe-V-Ti矿床而闻名。云南牟定安益矿床位于峨眉山大火成岩省内带，是一个产于镁铁–超镁铁质岩体的大型钛磁铁矿铂族金属矿床，赋存有超过3600万t铁矿石（平均Fe2O3 为30% ）、约39000 kg的铂族金属（Pt+Pd，平均品位为0.35g/t），伴生可观的V2O5和TiO2矿产。含矿岩体呈岩脉状，岩性主要为含长单辉岩和含钛磁铁矿单辉岩，约占整个岩体的80%。笔者对安益岩体开展岩相学、主微量元素和Sr-Nd同位素研究发现，安益岩体显示轻稀土元素富集、重稀土元素亏损的特征，与峨眉山高Ti玄武岩地区化学特征相近；含钛磁铁矿单辉岩和含长单辉岩的εNd(t=260 Ma) 值为 −13.2～−11.3，(87Sr/86Sr)i 值为 0.708496～0.709269，具有强烈的富集特征；与峨眉山高Ti、低Ti玄武岩、橄榄岩具有相似的地幔岩浆演化序列，位于玄武岩演化系列的中基性端元。样品地球化学特征及模拟计算结果，表明安益岩体的母岩浆来源于深源地幔的部分熔融，且源区含有富集特征的地壳再循环物质；岩浆演化过程中经历了显著的单斜辉石、斜长石及Fe-Ti氧化物的分离结晶，上升侵位过程中发生了较低程度的地壳混染，最终形成具有钛磁铁矿–铂族元素矿化的镁铁–超镁铁岩体。

    Magmatic deposits associated with mafic-ultramafic intrusions, including sulfide and oxide deposits, play a crucial role in hosting Ni-Cu-PGE-Fe-V-Ti mineral resource. Numerous such intrusions within the Emeishan Large Igneous Province (ELIP) are known for their significant Ni-Cu-PGE-Fe-V-Ti minerals. The Anyi intrusion, located in the central zone of ELIP, 840 m in length and 400 m in width of the outcrop, mainly composed (~80%) of plagioclase-bearing clinopyroxenite and titanomagnetite-bearing clinopyroxenite, hosting over 364 Mt of iron ore and ~39, 000 kg of platinum group element (Pt + Pd), with average grades of ~30 wt.% Fe2O3 and 0.35 g/t PGE, along with variable amounts of V2O5 and TiO2. In this paper, we present data on the major and trace elements and Sr-Nd isotope geochemical characteristics of the Anyi intrusion. These data showing the light rare earth elements (LREE) enrichment and heavy rare earth elements (HREE) depleted, similar with the Emeishan basalts. The εNd (t=260 Ma) of titanomagnetite-bearing clinopyroxenite and plagioclase-bearing clinopyroxenite in Anyi intrusion from −13.17 to −11.30, and the value of initial (87Sr/86Sr) is between 0.708496 and 0.709269, showing an enrichment feature, which share the same magma evolution trend with the Emeishan high-Ti and low-Ti basalts and peridotites, and locating in the mafic end member of the basaltic magma evolution series. The geochemical characteristics and simulation calculations of the samples indicate that the parental magma of the Anyi intrusion comes from the partial melting of deep mantle source, with the addition of recycled crustal materials in the mantle source. The parental magma mainly experienced the fractional crystallization of clinopyroxene, plagioclase, and Fe-Ti oxides, and underwent a low degree of crustal contamination during its ascent and emplacement.
