The Bondar Hanza porphyry Cu deposit, hosted by a granitoid stock, is located 120 km south of Kerman city in the elongated NW–SE trending Urumieh‐Dokhtar magmatic arc (UDMA), Iran. The granitoid stock is a multiphase intrusive body, 2 km² in surface area, which comprises microdiorite–microquartz diorite and granite–granodiorite. Petrological and geochemical analyses show that granitoids are peraluminous, magnesian, calcic to alkali‐calcic, and non‐adakitic intrusions characterized by negative Eu* anomalies. Thermobarometric and oxygen fugacity calculations indicate that magma emplacement occurred at 719–784°C, <100 MPa, and at a log fO₂ of NNO +1.6 to +3.2. Sulphur isotopic composition of sulphide minerals (δ³⁴S = 5.0–6.8 ‰) are similar to other porphyry Cu deposits worldwide. Molybdenite separates yield Re–Os ages of 28.22–28.03 Ma, indicating that the Cu mineralization and associated magmatism occurred during the Oligocene. The Bondar Hanza is one of the several granitoids from small porphyry Cu deposits in the UDMA that is related to island arc sub‐productive granitoids. It seems that the largest ore‐hosting porphyry systems within the UDMA are generally restricted to Miocene intrusions with adakitic affinity (e.g., Sarcheshmeh granitoids) and that the temporally discrete non‐adakitic magmatic systems are sub‐productive to barren. These data are interpreted to show that magmatism in the Bondar Hanza region was likely associated with partial melting of juvenile lower crust induced by north‐eastward subduction of the Neo‐Tethys oceanic lithosphere.

伊朗邦达尔汉扎斑岩铜矿床（Urumieh-Dokhtar岩浆弧）中的辉钼矿Re-Os年代学，岩石学和花岗岩的地球化学：岩石成因，矿化和构造环境的见解

Bondar Hanza斑岩型铜矿床由花岗岩类储藏，位于克尔曼市以南120公里，位于拉长的西北向东南走向的Urumieh-Dokhtar岩浆弧（UDMA）中。花岗岩类物质是一种多相侵入体，表面积为2 km ²，由微闪长岩－微石英闪长岩和花岗岩－白闪长岩组成。岩石学和地球化学分析表明，花岗岩类为高铝质，镁质，钙质至碱钙质，非ad质岩侵入，其特征是Eu *异常。热压法和氧气逸度计算表明，岩浆沉积发生在719–784°C，<100 MPa，log f O ₂为NNO +1.6至+3.2。硫化物矿物的硫同位素组成（δ ³⁴S = 5.0–6.8‰）与全球其他斑岩铜矿床相似。辉钼矿分离出的Re-Os年龄为28.22-28.03 Ma，表明在渐新世期间发生了铜矿化和相关的岩浆作用。Bondar Hanza是UDMA中小斑岩型铜矿床中的几种花岗岩中的一种，与岛状弧亚生花岗岩有关。看来，UDMA中最大的含矿斑岩系统通常仅限于具有adadtic亲和力的中新世侵入体（例如，Sarcheshmeh花岗岩），并且时间上离散的非adaktic岩浆系统对贫瘠的副生。这些数据被解释为表明，邦达尔汉扎地区的岩浆活动可能与新特提斯大洋岩石圈向北俯冲引起的少年下地壳的部分融化有关。
