摘要
河南省崤山地区的地层具典型地台型双层结构,其结晶基底为一套中深变质岩系,前人将其解体为两部分:一部分为太古宙变形变质花岗岩系(TTG--G),不具地层意义;另一部分为呈残留顶盖或包体形式残存于TTG--G中的壳岩系,并将其划分为新太古代兰树沟岩组和杨寺沟岩组。通过2009—2014年开展的1∶5万矿产地质调查工作,将这一套表壳岩新建为新太古代崤山岩群,可与登封地区的新太古代登封岩群对比。
The strata in Xiaoshan area of Henan have a typical platform type double-layer structure,with a crystalline basement composed of metamorphic rock series. They have been disintegrated into two parts,of which one is Archean metamorphic granite series( TTG--G),without formation significance,whereas the other part is a residual cap or inclusions in TTG--G supracrustal rocks. The latter part is divided into two lithostratigraphic units,namely Neoarchaean Lanshugou and Yangsigou rock groups. Through the 1∶ 50 000 mineral geological survey work in 2009—2014,the authors name this metamorphic rock series as Xiaoshan Group,which can be correlated with Neo-archaean Dengfeng Group.
