| 摘 要： | 作者通过对胶东地区太古宙变质岩详细的野外工作和室内研究,用角闪石环带及共生矿物组合两种方法确定了该区变质作用的pTt轨迹。并认为,搞清该区的构造序列、变质作用和岩浆作用期次、生长环带与扩散环带的判别标志都很重要。这对研究和确定胶东地区早期地壳的热演化史和构造形变史都具有重要的意义。

| Abstract: | The pTt paths of metamorphism in eastern Shandong were determined from amphibole zoning and paragenetic mineral assemblages based on detailed field investigation in-house research work on the Archean metamorphic rocks there. Also,it is very important to find out the structural sequence,the episodes of metamorphism and magmatism,and the discriminant signs of growth zoning and diffusion zoning. This is of vital significance for studying and determining the history of thermal evolution and tectonic desormation... |
