New perspectives on ophiolite formation: evidence from UHP, highly reduced and crustal minerals in mantle peridotites and podiform chromitites

摘要：

　　The presence of ultrahigh pressure (UHP), highly reduced, and crustal-type minerals in podiform chromitites and mantle peridotites of many ophiolites in Tibet, Myanmar, Russia and Northern China is difficult to reconcile with evidence for ophiolite formation in suprasubduction zone mantle wedges.The UHP and highly reduced minerals must have crystallized at least in the lower parts of the upper mantle and perhaps even deeper.
