在我国最主要的火山岩型铀矿带,分布于赣杭构造带,本文对该区地质特征进行简略论述,主要阐述了该成矿带铀矿地质研究(重点论述相山地区)近年来研究新进展,主要有:相山火山盆地侵入杂岩时代在132Ma～142Ma之间,形成于早白垩世;相山矿田铀成矿是一个连续的过程,成矿年龄145～85Ma;重,磁反演界面交线(GM线)可以作为相山铀矿的找矿依据;白垩世岩浆活动的有力证据是含铀火山盆地中的酸性-侵入岩,位于我国赣杭构造带上。其特征,通过科考都符合A型岩浆岩的时代地球化学特性。,最后简要论述了研究所存在的问题。
In our country the most important volcanic type uranium belt, located in the Gan-Hang tectonic belt, this article briefly discusses the geological characteristics of the area, mainly describes the research of uranium deposit geology (focusing on Xiangshan area) The main progresses are as follows: the volcanic rocks in the Xiangshan volcanic basin were between 132Ma and 142Ma and formed in the Early Cretaceous; the mineralization of uranium in the Xiangshan orefield is a continuous process with the age of 145 ~ 85Ma; the interface of gravity and magnetic inversion The line of intersection (GM line) can be used as a prospecting basis for the Xiangshan uranium deposit. The strong evidence of the Cretaceous magmatic activity is the acid-intrusive rock in the uranium-bearing volcanic basin, which is located on the Gan-Hang structural belt in China. Its characteristics are consistent with the age geochemical characteristics of type A magmatic rocks. Finally, it briefly discusses the problems existing in the research.
