赣杭构造火山岩带铀成矿规律及深入找矿

Uranium Metallogenic Regularity and Further Exploration in Gan-Hang Tectono-Volcanic Belt

赣杭构造火山岩带的形成是区域构造环境演化的产物,晚中生代强烈的构造、火山岩浆活动孕育了大规模铀成矿作用,形成了区域上北东向的构造岩浆成矿带。通过对铀矿时空分布、控矿因素、成矿规律及成矿作用研究,认为不同级别成矿单位的铀矿受火山构造、断裂构造联合分级控制,不同类型铀矿床的定位既有受构造控制的普适性、亦有受其它因素控制的特殊性,并进而提出了赣杭构造火山岩带新一轮找矿的目标和方向。

Formation of Gan-Hang tectono-volcanic belt is the result of regional tectonic evolution. Late Mesozoic tectonism and volcano magmatism produced large scale uranium metallogenesis and formed NE regional tectono-magmatic metallogenic belt. Through study on temporal and spatial distribution of uranium deposits, ore-controlling factors, metallogenic regularity and metallogenesis, metallogenic regularity metallogenic units of different classes are controlled by combination of volcanic structure and fault. Location of uranium deposits of different types are not only universally controlled by structure, but also controlled specially by other factors. The target and direction for an new round exploration in Gan-Hang tectono-volcanic belt are put forward.
