阿尔金成矿带加里东期主要成矿系统

Main Metallogenic Systems of the Alytn Metallogenic Belt in Caledonian

在分析加里东期成矿环境的基础上,系统阐明了阿尔金成矿带加里东期主要成矿系统的基本结构,研究了主要成矿系统的特点、形成动力学条件及其演化特征。认为阿尔金成矿带加里东期主要发育了喷流热水沉积,岩浆热液和基性超基性岩三大成矿系统,成矿作用与加里东期阿尔金南北缘板块伸展-汇聚-碰撞的构造运动旋回密切相关。文章最后提出了进一步成矿远景。

Based on the analyses of metallogenic setting in Caledonian, this paper studies on the structure of main metallogenic systems of Alytn metallogenic belt, and deals with in detail the characteristics, dynamical conditions and evolvement of the main metallogenic systems. Three metallogenic systems are defined in the area, including sedimentation exhalation hot water metallogenic system, magmatic hydrothermal metallogenic system and basic-ultrabasic magma liquation metallogenic system. Mineralizations were closely related to plate tectonic cycle of extension-convergence-collision. At the end of this paper, regional potentiality assessment of mineral resources, mineral resource reconnaissance and mineral resource prospecting are suggested.
