Transformation of refractory cratonic mantle into more fertile lithologies is the key to the fate of cratonic lithosphere. This process has been extensively studied in the eastern North China Craton (NCC) while that of its western part is still poorly constrained. A comprehensive study of newly-found pyroxenite xenoliths from the Langshan area, in the northwestern part of this craton is integrated with a regional synthesis of pyroxenite and peridotite xenoliths to constrain the petrogenesis of the pyroxenites and provide an overview of the processes involved in the modification of the deep lithosphere.

黄铁矿异岩在华北克拉通西北部深层岩石圈中记录了复杂的熔体浸渍

难处理的克拉通地幔转变成更富饶的岩性是克拉通岩石圈命运的关键。华北克拉通东部（NCC）对此过程进行了广泛的研究，而西部的克拉通仍然受限制。对这个克拉通西北部狼山地区新发现的辉石岩异岩进行了全面的研究，并结合了辉石岩和橄榄岩异岩的区域合成，以限制辉石岩的成岩作用，并概述了改性过程深岩石圈。
