中文摘要: 横涧-岗上英铀矿床产在相山大型塌陷式火山盆地的北部,区域NE向、EW向断裂构 造与火山构造复合控制次花岗斑岩体和铀矿床的定位,矿区次花岗斑岩的产出明显受到高角 度逆断层的制约,铀矿化主要受构造裂隙控制,含矿裂隙带沿斑岩体内外接触带呈弧形展布。依据横涧-岗上英地区次花岗斑岩岩体及矿体空间展布及产状特征,厘定了控岩构造系统,通过分析构造裂隙特征及其与铀矿化的关系,划分了成矿前、成矿期、成矿后构造体系,初步认为矿区的构造演化可分为三期6个阶段。
Abstract:The Hengjian Gangshanying deposits are located in the north of Xiangsh an collapse volcanic basin. Regionally the NE and EW striking faults and volcani c faults jointly exert control on the position of subgranitic porphyry and urani um deposits. Locations of subgranitic porphyry are obviously confined by high a n gle thrusts, and uranium mineralization is primarily controlled by fissures. The ore bearing fissures display an arch extension along inner and outer contact z o nes of the porphyry. Based on spatial distribution and attitude of subgranitic p o rphyry in the Hengjiang Gangshangying area, this paper has defined the system o f rock controlled structures. By analyzing the relationship between structural f i ssures and uranium mineralization, the authors have divided the structure system into pre ore stage, ore stage and post ore stage, and believed that the struc tures experienced 3 epoches with 6 stages.
