Amphibole, an important product during retrogression of UHP eclogite to amphibolite, exhibits few brittle deformation features, and does not show any intragranular microstructures indicative of crystal deformation such as undulose extinction, deformation lamellae, subgrain boundary and bulging.

角闪石是超高压榴辉岩退变质过程的产物，在光学显微镜下没有明显的脆性破裂变形，也不显示任何指示晶体塑性变形的晶粒内部显微构造，例如不均匀消光、变形叶理、亚颗粒边界和凸出褶皱等。

The high-grade metamorphic terrain of Hengshan located at the hinderland of North China Carton in northern part of Shanxi province, China, is a middle-lower crustal transition area of the typical continental crustal profiles of the Wutaishan—Hengshan—Datong—Jining of the early Precambrian etamorphic terrain in China.The Hengshan gneisses of the amphibolite—granulite facieses metamorphic terrain consist of the TTG gneisses and the horizontal adding mantle materials. The Supracrustal rocks in this area are composed of the mafic volcanic rocks and sedimentary rocks. The plenty of granitoid magma activities are the result of anatexes.

Eclogites north of the fault give similar Sm–Nd isochron ages (131–126 Ma) but otherwise differ in that they are strongly overprinted by a lower pressure assemblage and, along with associated HP/LT rocks, give much younger 40Ar/39Ar ages of 88–55 Ma indicating a later amphibolite facies metamorphic event.

榴辉岩断层以北的始可予以实现位置相似的Sm - Nd同位素年龄（131-126 Ma）的方式不同，但他们强烈较低的压力叠加和组合，以及相关的惠普/审裁处的岩石，让更年轻的40Ar/39Ar年龄在88-55马说明后来角闪岩相变质事件。
