发现36亿年前古地壳残体中国地质科学是最近在中国部阿尔金山东段海拔2636米的阿克塔什塔格山,发现36.5亿年前,体积迭600万立方米的古地壳残体。专家认为,这一发现使中国成为世界上第四个拥有珍贵的古地壳资料的国家。这对研究了解地球演化、地壳结构、板块漂移和中国宏观地质结构等,具有很高的科学价值。此前,梅华林、陆松年等科技人员在祁连山西段甘肃省北蒙古族自治区古包城,发现了26亿年前的黄岗片麻页岩。他们在继续向西寻找更古老岩石时,发现由灰白色花岗片麻
Discovering Paleo-Crustal Debris 3.6 Billion Years ago China Geosciences, recently discovered in the Aktastag Mountains at 2636 meters above sea level in the eastern part of the Altun Mountains in the Chinese Ministry of Mudanjiang, discovered that the ancient crustal debris with an area of 6 million cubic meters was deposited 3.65 billion years ago . According to experts, this discovery made China the fourth country in the world with precious paleo-crustal data. This study of the understanding of the evolution of the Earth, the crustal structure, plate drift and China’s macroscopic geological structure, has a high scientific value. Earlier, Mei Hualin, Lu Songnian and other scientific and technological personnel in the western Qilian Mountains Gubei Autonomous Region, the ancient city of Baoji City, found 2.6 billion years ago Huanggang flax shale. As they continued to search for more ancient rocks westward, they found flaxseed on white and gray granite
