Abstract

The Motykleisky, Chistoozerny, and Pavlovichsky new ore clusters promising for porphyry molybdenum-copper mineralization have been identified in the Magadan region due to results of creation of the State Geological Map 1000/3, sheets O-55, O-56. The porphyry-type mineralization is associated with the Priokhotsky plutonic belt of Albian-Cenomanian granitoids of the Magadan suite of the calca-reous-alkaline series (K/Na <1). The granitoids are dominated by porphyritic tonalites and quartz diorites of type I magnetite series, often adakitic in composition. The mineralization is accommodated by the Juras-sic-Lower Cretaceous island-arc sedimentary-volcanic formations. Relationship between the minerali-zation and granitoids is substantiated by the U-Pb SIMS SHRIMP and Re-Os TIMS dating. In potential ore clusters, the mineralization is manifested by extensive fields of hydrothermal-metasomatic alterations (propylites and quartz-sericite-pyrite metasomatites). Recommendations are given for follow-up large-scale geological survey and prospecting in the area of the potential ore clusters.
