西天山阿吾拉勒铁矿带是天山成矿带今年找矿的一个突破,也是全国关注的一个焦点。近来,围绕着它的成因及背景,展开了一系列的研究与讨论。其中主要是2个观点:一为板块碰撞论,认为阿吾拉勒成矿亚带是伊犁微板块、准噶尔板块、塔里木板块晚古生代(石炭纪-二叠纪)碰撞的结果;二为陆内裂谷论,即上述板块在泥盆 The West Tierra Verde iron ore belt is a breakthrough in the prospecting of the Tianshan metallogenic belt this year, and is also a focus of attention of the whole country. Recently, around its causes and background, launched a series of research and discussion. Among them, there are two main points: one is plate collision theory, which means that the Ulalale metallogenic belt is the result of late Paleozoic (Carboniferous-Permian) collision in Ili plate, Junggar plate and Tarim plate; Valley theory that the above plate in the Devonian
