朝鲜半岛中部的构造、岩石和地质年代学资料表明,中国中东部的秦岭—大别山—苏鲁碰撞带穿越黄海延伸至临津江带。首次鉴定为临津江带西部的 Yeoncheon 杂岩,主要包含有向北倾斜的变质层序:(1)北部 Jingok单元,由巴罗型变泥质岩组成;(2)南部 Samgot 单元,由钙硅酸盐岩和角闪岩组成。Jingok 单元内,主要是具逆向剪切、向南倾倒的构造。而晚期的正向剪切发育于 Samgot 单元和其南部的变形花岗岩中。这些构造样式被解释为碰撞带挤压后抬升中伴生的伸展变形。角闪岩估算的压力-温度(p-T)指示,高压角闪岩相变质作用(8×10~8Pa～13×10~8Pa 和630～790℃)可能是榴辉岩相沿右旋 p-T 轨迹演化而成。Sm-Nd 和 Rb-Sr 地质年代学资料表明,晚元古代侵入的角闪岩在二叠—三叠纪期间变质。
The tectonic, lithological and geochronological data in the central part of the Korean Peninsula indicate that the Qinling-Dabieshan-Sulu collision zone in the central and eastern part of China stretches across the Yellow Sea to the Imjin River. It was first identified as the Yeoncheon complex in the western part of Linjinjiang Belt, which contains mainly metamorphic sequences inclined northward: (1) North Jingok unit, consisting of Barrow-type argillaceous rocks; (2) South Samgot unit composed of calcium-silicon Acidite and amphibolite. Within the Jingok cell, there are mainly structures that are reversely sheared and dumped southward. The late positive shear developed in the Samgot unit and its southern deformed granite. These structural styles are interpreted as the accompanying deformation of the collision zone during extrusion. The pressure-temperature (pT) estimates of amphibolite indicate that the amphibolite facies metamorphism (8 × 10 ~ 8Pa ~ 13 × 10 ~ 8Pa and 630 ~ 790 ℃) to make. Geochronological data of Sm-Nd and Rb-Sr indicate that the Permian intrusive rocks of the Late Proterozoic metamorphic during the Permian-Triassic period.
