| 摘 要： | 延边金谷山地区二叠纪"柯岛岩组"为一套低绿片岩相变质岩系,其原岩为一套酸性-中酸性火山碎屑沉积岩系.通过剖面详细测量和岩石学研究,建立了该地区"柯岛岩组"层序,划分了6个火山喷发-沉积旋回,并依据各旋回序列岩相组合特征,恢复了该地区在陆表海裂陷(槽)构造条件水下火山喷发-沉积作用及演化环境.

| Abstract: | The Permian Kedao Formation in the Jingushan area,Yanbian belongs to a succession of metamorphic rocks of low greenschist facies. Their parental rocks consist of a set of acid-intermediate-acid pyroclastics. Based on detailed profile measurement and petrological studies, the sequence of the Kedao rock Formation in the area has been set up and six volcanic eruption-sedimentation cycles are divided. Based on the lithofacies and their association of each cycle, a tectonic setting in which marine volcanic eruption and sedimentation in an inland rift is reconstructed. |
