DISCOVERY OF LATE MESOZOIC MAGMATIC ROCKS IN ORDOS ANCIENT CONTINENT NUCLEUS AND ITS GEOLOGICAL IMPLICATION
-
摘要:
在古老、稳定的鄂尔多斯古陆核上, 经过初步的金刚石找矿工作发现了一些来自深源的金刚石指示矿物; 并在这些指示矿物异常区的源头, 发现了玄武质岩浆岩。这些深源岩浆主要呈弱的喷发或爆发形式或裂隙式贯入为表现特征。它的发现可以证明冀鲁辽古陆核在中生代强烈活化的同时, 鄂尔多斯古陆核也出现较弱的岩浆活动。它提供了一个研究大陆岩石圈的窗口, 同时对本地区的金刚石找矿可能具有指导意义。
Abstract:In the ancient and stable Ordos continent nucleus, we found deep-seated indicator minerals diamond in a preliminary exploration, and basaltic magmatic rocks in the source area of anomaly of indicative of the minerals.This deep source magma mainly occurs as weak eruption or explosion, or fissure injection.This discovery reveals a weak magmatic activity in the Ordos ancient continent nucleus during the Mesozoic when Hebei-Shandong-Liaoning ancient continent nucleus was activating.It can not only provide a window for research on continental lithosphere, but also prove to be of great significance to the exploration of diamond in this area.
