Formation of the Sole of the Oman Ophiolite

洋壳切片(蛇绿岩)侵位在许多造山带中，大多数在其底部具有异常陡峭的反转变质梯度。这些倒置的梯度被认为是同步断裂和变质作用的产物，但其中涉及的机制细节仍不清楚。这项研究将研究阿曼蛇绿岩底部的岩石，这是世界上暴露最多、最知名的蛇绿岩之一，以确定典型的逆变质梯度的微结构、温度气压和热年代学历史。这一结果将对所有含蛇绿岩的山脉的构造演化具有重要的意义。

Slices of oceanic crust (ophiolite) are emplaced into many orogenic belts and most have unusually steep, inverted metamorphic gradients at their base. These inverted gradients are thought to be the product of synchronous faulting and metamorphism but the details of the mechanisms involved are still unknown. This study will examine the rocks at the base of the Oman ophiolite, one of the best exposed and best known in the world, to determine the microstructural, thermobarometric and thermochronologic history of an archetypical inverted metamorphic gradient. The results will have important implications for the tectonic evolution of all mountain belts that contain ophiolitic rocks.
