前言古陆块是前寒武纪或大或小的盆地沉积的见证.在古陆块及其边缘,的确存在着储量大、品位富的沉积变质铁矿床,亦有规模巨大的、与岩浆成因有关变质富铁矿床.此外,国家急需的黄金、金刚石、铬、镍、钒、钛、蓝石棉、钻、铂和放射性矿产资源在古陆块占有相当重要的位置;古陆块中,又往往出现深大断裂,它们的继承性明显地控制着岩浆的侵入活动和矿产资源的分布.研究古陆块是为了探索地球及地壳物质起源和早期演化的基础;对认识地球上生命
Preface The ancient block is evidence of pre-Cambrian sedimentation in large or small basins. There are indeed deposit-denudation iron deposits with large reserves and high grade in the ancient continental block and its margins, In addition, the gold, diamond, chromium, nickel, vanadium, titanium, blue asbestos, diamond, platinum and radioactive mineral resources urgently needed in the country occupy a very important position in the ancient land mass; in the ancient land mass, And often appear deep faults, their succession obviously controls the magmatic intrusion activity and the distribution of mineral resources.The study of ancient landmass is to explore the origin of the earth and crustal material and early evolution of the foundation; understanding of life on Earth
