云南和四川在我国西南三江地区新生代成矿区(带)中占有重要地位,那里分布着一系列各具特色的大型超大型矿床,包括金顶铅锌矿、牦牛坪稀土矿床、哀牢山金矿等。以这些典型矿床为基础,分别构成了一系列矿集区。通过对矿集区成矿条件和成矿系列的研究,本文初步认为,四川和云南在新生代成矿作用方面既有共性又有个性,其共性表现在均受新生代大陆动力学总格局的宏观制约,呈现出“两横两纵两斜加一点”的矿集区分布格局形成若干成矿集中期;个性则突出地表现在“南锗北碲”、“南岩浆北构造”、“南煌斑岩北辉绿岩”、“南盆地北剪切”、“南氧化北冲积”、“南减薄北隆升”等方面。其原因除了与新生代表壳构造活动有关外,还受到各地新生代以前地质-成矿作用继承性的影响和新生代不同地区出现不同类型的幔源岩浆-流体-热事件的制约。
Yunnan and Sichuan occupy an important position in the Cenozoic metallogenic belt (belt) in the Sanjiang area of southwestern China, where a series of large-scale superlarge deposits with different features, including Jinding Pb-Zn deposit, Maoniuping REE deposit, Mine and so on. Based on these typical deposits, a series of ore-collecting areas are formed respectively. Based on the research on metallogenic conditions and metallogenic series in the ore district, the paper preliminarily considers that both Sichuan and Yunnan have commonness and individuality in the mineralization of the Cenozoic. Their common properties are both affected by the overall pattern of the Cenozoic continental dynamics Macro-control, showing a “two horizontal and two vertical and two oblique plus a point,” the distribution pattern of the ore-gathering area to form a number of mineralization concentration period; personality is highlighted in the “South Germanium North Tellurium”, “South” “, ” Nanhui porphyry North diabase “, ” South basin north shear “, ” South Oxidation North alluvial “, ” South thinning North Longlingsheng "and so on. The reason is not only related to the tectonic activity of Cenozoic crust, but also influenced by the succession of geology and mineralization before Cenozoic in different places and the occurrence of different types of mantle magmatic-fluid-thermal events in different areas of Cenozoic.
