摘要
朝鲜北部及其邻区的第四系更新统(Q_1)由玄武岩和碎屑岩互层组成。下更新统玄武岩是在新第三纪上新世广而平坦的侵蚀面上形成的台地型玄武岩。朝鲜北部及其邻区的地形构造是通过下更新统沉积以后发生的新构造运动形成的。朝鲜下更新统和上更新统中的沉积矿产(特别是砂金矿床)普查、开发远景很大。
The Pleistocene basalt and clastics are distributed in northern Korea and its vicinity.The lower Pleistocene basalt is referred to platform basalt formed on broad and flat erosion surface of Plioeene. The topography in the area is formed by the neotectonic movements after the lower Pleistocene sedimentation. There is a great commercial potential for prospecting and exploitation of lower Pleistocene sedimentary mineral resources (particularly placer gold deposit).
