摘要
乌伦布拉克角砾岩筒型铜钼矿床,成矿严格受中酸性浅成岩浆岩组合-北西向构造破碎带-特定层位(中泥盆统北塔山组)复合控制,矿体具有中强磁性和中等强度的激发极化特性.在矿区北部外围,重要控矿断裂构造的北西延伸方向上存在大规模化探铜异常.综合物探资料表明该区地层和岩浆岩分布与已知矿区类似,在化探铜异常中心部位存在走向与控矿断裂构造基本一致、异常特征与已知矿体类似的大规模磁异常.地质、地球物理特征指示出矿区及其北部外围存在深部扩大找矿的良好前景.
The forming of Wulunbulake copper-molybdenum mine is controlled by intermediate-acid hypabyssal intrusive magmatic formation, faults of NW- SE strike and specific stratum. Geophysical characteristics of the ore body are middle-strong magnetic and middle induced polarization. A geochemical copper anomaly of largescale is located at areas in the northwest extension of the fault which is the controlling structure of the mine. Geophysical data indicates that this area has similar stratum and magmas to the copper-molybdenum mine. In the center of geochemical copper anomalies, magnetic anomalies of large-scale present the same strike direction with the faults and similar character of the known mine. All these indicate that there is a bright future to find mine deposits of lager scale in the area.
