| 摘 要： | 给出了中亚成矿域的地质含义与地理范围。此巨型成矿域以发育中、晚元古代及晚古生代成矿作用为其特点。以超大型矿床为重点,并主要围绕金、铜讨论了中亚成矿域6种类型矿床的时空展布。近年取得的进展说明,中亚成矿域在矿产资源优势与潜力方面并不亚于环太平洋成矿域及特提斯成矿域。

| Abstract: | The Central Asia Metallogenic Province is referred to areas situating between the Siberian craton to the north and the Sino-Korean, the Tarim and other cratons to the south. This metallogenic province is characterized by the Mid-Late Proterozoic and the Late Paleaozoic mineralizations. The spatial and temporal regularities of six important types ore deposits with special reference to Cu and Au super-large ones are discussed. It follows from the discussion that the Au-PGE-Ag-W deposits in carbonaceous formations and the massive sulfide deposits are highly perspective, while the porphyry deposits, the rulaesial volcanics-hosted Au deposits, the ore formations related to alkaline-rich intrusive rocks and the sandstone Cu deposits are also important for this particular province. With respect to ore potentiality, the central Asia Metallogenic Province occupies a position not less significant than the circum-Pacific and the Tethys Metallogenic Provinces. |
