Abstract The Jijal Complex, one of the largest Neo-Tethyan ophiolites (ca. 150 km2) in Pakistan, occupies a deep-level section of the Cretaceous Kohistan Arc that was obducted along the Main Mantle Thrust or Indus Suture Zone. Peridotites of the Jijal Complex consist mainly of harzburgite and dunite with numerous podiform chromitites. In this paper, we present new mineral compositions, whole-rock major elements, trace elements, rare earth elements (REEs) and platinum group elements (PGEs) to evaluate the melt evolution and petrogenesis of these rocks. Chromian spinel in the chromitites is fairly uniform in composition with Cr#s ranging from 75 to 81, Mg#s from 59 to 63 and TiO2

巴基斯坦北部主地幔逆冲断层（MMT或印度河缝合带）Jijal杂蛇绿岩中橄榄岩和铬铁矿的矿物学和地球化学

摘要 Jijal 杂岩体是巴基斯坦最大的新特提斯蛇绿岩之一（约 150 平方公里），位于沿主地幔逆冲断层或印度河缝合带外展的白垩纪科希斯坦弧的深部。Jijal 杂岩的橄榄岩主要由菱镁矿和纯英岩组成，并带有大量豆状铬铁矿。在本文中，我们提出了新的矿物成分、全岩主元素、微量元素、稀土元素 (REE) 和铂族元素 (PGE)，以评估这些岩石的熔体演化和成岩作用。铬铁矿中的铬尖晶石成分相当均匀，Cr#s 范围从 75 到 81，Mg#s 从 59 到 63 和 TiO2
