| 摘 要： | 中亚成矿域地质演化的重要特征是:古生代地壳生长和演化的多阶段性、多旋回物质的活化-再活化、成矿环境的长期性和周期性,这些特征导致域内成矿物质的多次迁移和聚集。中亚成矿域由若干个成矿省组成,其核心部分由阿尔泰成矿省、环巴尔喀什-准噶尔成矿省和中-南天山成矿省构成。成矿省由多个成矿带构成,每个成矿带由若干个矿集区组成,每一个矿集区包含至少1个大型—超大型矿床。古亚洲洋关闭后,中亚成矿域核心地区普遍发育的印支期成矿作用主要受韧性剪切带和小型壳源岩浆活动控制。中亚成矿域核心地区的关键科学问题包括古南天山俯冲带流体-岩浆演化过程对成矿作用的制约、巨型斑岩铜矿带的形成环境、晚古生代大地构造格局重建、巨型韧性剪切带的特征及其对金成矿作用的控制机制。

| Abstract: | The important characteristics of the geological evolution in the core part of the Central Asian metallogenic domain are its multi-stage growth and evolution of Paleozoic crust, polycyclic mobilization-remobilization materials and long-continued and cyclic metallogenic environment. These characteristics determined multiple transport and concentration of ore-forming materials. This metallogenic domain comprises several metallogenic provinces and its core part is composed of the Altay, circum-Balkhash-Junggar and Central-South Tianshan metallogenic provinces. A metallogenic province includes several metallogenic belts, each metallogenic belt is made up of several ore deposit concentration areas, and each ore deposit concentration area contains at least one large or superlarge deposit. After the closing of the Paleo-Asian Ocean, the Indosinian metallogenesis developed in the core of the Central Asian metallogenic domain was mainly controlled by ductile shear zones and small-scale crust-derived magmatism. The key scientific problems in the core of this metallogenic domain include the constraint of the fluid-magmatic evolution on mineralization in the Paleo-South Tianshan subduction zone, environment for the formation of the gigantic porphyry copper belt, reconstruction of the Late Paleozoic tectonic framework, characteristics of the gigantic ductile shear zone and its controlling mechanism for gold mineralization. |
