| 摘 要： | 在近年来中亚造山带东段多金属矿床研究取得新进展的基础上,选择铀、钼两类矿床,结合铀、钼元素的地球化学行为探讨成矿物质来源的多样性和成矿的多阶段演化。此外,从构造研究角度,结合中亚造山带东段中大量中间地块存在的构造现象,讨论中间地块与成矿作用的关系:中间地块经历了从大陆边缘的裂解、漂移和板块碰撞造山作用,在漫长而复杂的地质过程中遭受的多次改造,有利成矿物质的反复被萃取和聚集。最后提出印支期华北克拉通北缘和北部造山带的成矿作用与底侵背景下的伸展作用密切相关。

| Abstract: | Based upon recent research achievements on polymetallic ore deposits in the eastern section of Central Asian orogenic belt,the authors selectively studied uranium and molybdenum deposits,to explore diversity of the metallogenic sources and the various stages of mineralization in connection with the geochemical behaviors of uranium and molybdenum elements.Because there are many medium massifs,the relationship between mineralization and the medium massifs is also discussed from view of tectonics.These medium ... |
