引言 在伊拉克阿耳卑斯造山带已划分出两个基本构造单元。北部冲断层带属于陶尔褶皱带成矿区,而推复带却是伊朗褶皱带成矿区的一部分。 从成矿作用观点来看,北部冲断层带的特点是存在铅、锌矿床,大都伴有重晶石矿床,偶尔伴有萤石矿床。铜很少存在,而且量也很少。该区还产有菱铁矿脉,而伊朗褶皱带的推复带则以铜-铁-铬铁矿矿化为特征。 北部冲断层带由古生代、中生代和新生代沉积岩
Introduction Two basic tectonic units have been delineated in the orogenic Alps of Iraq. The northern thrust belt belongs to the Taur fold belt metallogenic belt, while the thrust belt is a part of the Iranian fold belt metallogenic belt. From the perspective of mineralization, the northern thrust belt is characterized by the presence of lead and zinc deposits, mostly associated with barite deposits and, occasionally, fluorite deposits. Copper rarely exists, and the amount is small. The area also produces siderite veins, while the Iranian fold belts are characterized by copper-iron-chromite mineralization. The northern thrust zone consists of Paleozoic, Mesozoic and Cenozoic sedimentary rocks
