摘要
文章应用地洼成矿理论和构造地球化学方法，研究了某地区Ｆ１等成矿断裂带的构造地球化学特点和元素的变化规律以及铀不断累增富集成矿的作用过程。在形成泥盆系富铀地层的基础上，经历了后期构造—岩浆活化作用的改造，形成预富矿化场—动力改造热液成矿，形成构造热液型铀矿化—表生淋积，形成叠生富矿段，使之发展成为具有层控、岩控、构控和时控等特点的多因复成型铀矿床，从而为本区进一步找矿指明了方向。
With the diwa metallogenic theory and tectonogeochemical
method ,this paper studies the tectonogeochemical characteristics of F1 metallogenic fault
zone 、variation laws of elements and the minerogenetic process in the aggregation of the
minerogenetic elements such as Uranium in somewhere. There will be produced primary
concentration mineralized zone through rebuilding of anaphoric tectono-magmation in the base
of formation of U-rich strata. And then formed tectonohydrothermal uranium mineralization with
the fault (dynamic) rebuilding hydrothermal metallogensis. With hypergone leach there will be
formed reaccrued rich-mine segment. At last it will be developed to polygenetic compound
U-deposit with strabound,rockbound, tectonobound, tirnebound features. this study might help to
point out the direction for prospecting in the area.
