Main Metallogenic Systems of the Alytn Metallogenic Belt in Caledonian

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.
