NEW ADVANCES IN THE STUDY OF THE DENGFENG COMPLEX IN THE SONGSHAN REGION, HENAN PROVINCE

  • 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.
