Signal intensity and system blank of five argon isotopes obtained indicate that the system blank level adopted by the authors is low enough to get a reasonable isochron age for single mineral grains frown Mesozoic or older samples.

获得的5个氩同位素空白本底水平表明，本系统已经完全具备对中生代或更老的地质样品进行单颗粒全熔法等时线定年的能力。

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。
