三九地区九龙江矿区铀成矿地质特征及铀矿体空间分布特征研究

Study on the Geological Characteristics of Uranium Metallogenesis and the Spatial Distribution of Uranium Ore Bodies in Jiulongjiang Mining Area in Sanjiu Area

三九地区位于诸广山岩体中南部,包括九曲岭、九龙径、九龙江三个地段及其周边地区。近年来,三九地区铀矿地质工作不断取得找矿突破,已成为一个新铀矿田。本文在简要介绍九龙江矿区铀成矿地质特征的前提下,重点研究了铀矿体的规模、形态、产状等地质要素的空间展布特征,总结了其空间分布规律,通过类比分析,最终提出该地区铀矿地质工作在空间上需要注意的找矿突破方向。

The Sanjiu area is located in the central and southern Zhuguangshan granite, which is composed with three areas named Jiuquling, Jiulongjing, Jiulongjiang and their neighboring areas. Along with the development of uranium geological works in Sanjiu area of recent years, it is expected to become a new uranium ore fi eld. In this paper, the geological characteristics of uranium metallogenesis are briefl y introduced, and the spatial distribution characteristics of uranium ore body size, shape and occurrence are further studied, and the spatial distribution regularities of the geological factors are summarized. Through analogical analysis, fi nally it proposed the porspecting direction of uranium geological works should be pay attention to in spatial distribution.
