中生代时期,西太平洋强烈地喷发了安第斯型钙碱性火山岩,新生代时期,东亚大陆火山岩浆活动转为以玄武岩浆喷发为主,中朝断块区的新生代玄武岩是其中具有代表性的一部分。六十年代至七十年代初,对玄武岩、金伯利岩及其中深源超镁铁质包体所进行的世界规模的研究,扩展了人们对上地幔的认识。这个时期普遍认为地壳是不均一的,但上地幔是均一的。七十年代中至八十年代初,随着人们对深源岩石的地球化学研究,尤其是对稀土元素和其它不相容元素以及锶、钕、铅、氧等稳定同位素的研究,逐渐认识到上地
During the Mesozoic era, the Andean-type calc-alkaline volcanic rocks erupted strongly in the western Pacific Ocean. During the Cenozoic, the volcanic magmatism in the East Asian mainland turned to basalt eruption, and the Cenozoic basalts in the fault zone of the Sino-DPRK were a representative part . From the 1960s to the early 1970s, the worldwide study of basalt, kimberlite and its deep-source ultramafic inclusions expanded the understanding of the upper mantle. The crust was generally considered heterogeneous during this period, but the upper mantle was uniform. From the mid-1970s to the early 1980s, with the study of the geochemistry of deep-source rocks, especially the study of rare-earth elements and other incompatible elements and the stable isotopes of strontium, neodymium, lead and oxygen, On the ground
