| 摘 要： | 经重新研究，将原登封群分为３套岩石序列：（１）新太古代构造地层单位登封岩群，为变质表壳岩系，代表绿岩建造；（２）新太古代构造岩石单位，为变质侵入岩系；（３）古元古代侵入岩系。它们共同构成嵩山花岗岩—绿岩地体。新太古代岩石经历了嵩阳运动第一幕（约２．５Ｇａ）、第二幕（约２．２Ｇａ）和中岳运动（约１．９Ｇａ）３个重要变质变形期，据此建立的ｐ—Ｔ—ｔ—Ｄ轨迹显示花岗岩—绿岩地体变质变形与陆壳碰撞隆升过程有密切关系

| Abstract: | Through a further study, the original Dengfeng Group is divided into three parts: (1) a Neoarchaeozoic tectonostratigraphic unit named the Dengfeng Group Complex, a meta surpracrustal rock series, representing the greenstone formation; (2) a Neoarchaeozoic tectono lithostratigraphic unit, a metamorphic intrusive rock series; (3) the Early Palaeoproterozoic intrusive rock series. All of the three parts combine to form the Songshan granite greenstone terrane. The Neoarchaeozoic rocks underwent three major stages of deformation and metamorphism: (1) the first episode of the Songyang orogeny (about 2.5 Ga); (2) the second episode of the Songyang orogeny (about 2.2 Ga); (3) the Zhongyue orogeny (about 1.9 Ga). The p T t D path shows that the deformation and metamorphism of the granite greenstone terrane were closely related to the process of the continental crustal collision and uplift. |
