在埃拉比迪(Errabiddy)地区,片麻杂岩位于西伊尔冈太古宙片麻岩区和加斯科尼省之间的过渡带中,太古宙片麻岩由于元古宙的变形、变质作用和火成活动而经受了广泛的改造,过渡带由两个地区的元古宙剪切带定界,虽然过渡带内部的片麻理和岩性层理随太古宙地层走向,而元古宙变形控制着狭窄的糜棱岩带。2650Ma的岩石钻孔花岗岩(Rocky Bore Granite)侵入于过渡带南部边缘的片麻岩中,提供了片麻岩的最
In the Errabiddy region, the Chematian complex is located in the transition zone between the Cyclone gneiss in the West Indies and the Gasconi province. Archean gneiss due to the deformation of the Proterozoic, Metamorphism and pyrogenesis have undergone extensive remodeling. The transition zone is delimited by the Proterozoic shear zones in both areas. Although the patches and lithology of the transitional zone follow the Archean stratigraphy, the Proterozoic The deformation of the universe controls a narrow mylonite belt. 2650 Ma rocky Bore Granite intrudes into the gneiss in the southern margin of the transitional zone, providing the most gneiss
