Pancarli Ni-Cu±(PGE) sulfide deposit occurs in the Neoproterozoic basement complex of the Bitlis massif, which is one of the Andean-type active continental margin fragments with arc-type assemblages represented by the Cadomian orogenic belt. Pancarli sulfides are associated with quartzo-feldspathic gneisses (country rock) and mafic intrusions (host rock). Composed of only semi-massive ore, the Ni-Cu±(PGE) sulfide deposit is a small-scale deposit, and it does not contain net-textured and disseminated ore. The mineral assemblage comprises pyrrhotite, pentlandite, and chalcopyrite. The semi-massive ore samples contain 2.2 wt.%−2.9 wt.% Ni, 0.8 wt.%−2.2 wt.% Cu (Cu/(Cu+Ni)=0.2−0.5) and 0.13 wt.%−0.17 wt.% Co. The Cu/Ni ratios (average 0.57) are consistent with the segregation of sulfides from a basaltic magma. Low Pt+Pd_100%S values of 0.08 ppm−0.89 ppm, relatively low Pt/Pd ratios of 0.2–1.4, and Pd/Ir ratios of 4.5–39 have also been revealed. These values demonstrate that the magma reached S saturation before its emplacement and the mineralization with high Cu/Pd ratios formed by sulfides segregated from a PGE-depleted magma. δ³⁴S isotope values (average −3.1‰) of Pancarli sulfides are lower than mantle source. Negative δ³⁴S value indicates contamination from surrounding rocks. Concerning the composition, remobilization style and magma type, the Pancarli Ni-Cu±(PGE) sulfide deposit is similar to the deposits associated with Andean-type magmatic arcs located in the convergent plate margin settings.

土耳其东部卡多布-阿瓦隆带的潘卡里岩浆岩性镍-铜±（PGE）硫化物矿床组成

Pancarli Ni-Cu±（PGE）硫化物矿床发生在Bitlis断层块的新元古代基底复合物中，这是安第斯型活动大陆边缘碎片之一，其弧形组合由卡多米山造山带代表。Pancarli硫化物与石英长石片麻岩（乡村岩石）和镁铁质侵入岩（基质岩石）有关。Ni-Cu±（PGE）硫化物矿床仅由半块状矿石组成，是小规模矿床，不包含网状和散布的矿石。矿物组合包括黄铁矿，方铁矿和黄铜矿。半质量矿石样品包含2.2 wt。％-2.9 wt。％的Ni，0.8 wt。％-2.2 wt。％的Cu（Cu /（Cu + Ni）= 0.2-0.5）和0.13 wt。％-0.17 wt。 Cu / Ni比（平均0.57）与玄武岩浆中硫化物的偏析相一致。低Pt + Pd _100％S还显示出0.08 ppm-0.89 ppm的Pt / Pd比值，0.2-1.4的相对低值和4.5-39的Pd / Ir比值。这些值表明，岩浆在其就位之前达到了S饱和，并且从贫化PGE的岩浆中分离出的硫化物形成具有高Cu / Pd比的矿化作用。δ ^34个硫同位素Pancarli硫化物的值（平均-3.1‰）比地幔源低。负δ ³⁴ S值表示来自周围岩石的污染。关于成分，迁移方式和岩浆类型，Pancarli Ni-Cu±（PGE）硫化物矿床与位于会聚板块边缘的安第斯型岩浆弧相关的矿床相似。
