Tectonic evolution and mineralization of the Leiwuqi-Zogang metallogenic belt

The Leiwuqi-Zogang metallogenic belt (LZMB) in eastern Tibet is an important metallogenic belt in the Sanjiang Tethys metallogenic domain, but the related researches are poor and scattered. Based on the latest research results, the deposits in the belt can be divided into six metallogenic series mainly according to metallogenic age, geological background, metallogenesis, and metallogenic element association, including: (1) Indosinian crystalline graphite deposits; (2) Weathering leaching magnesite deposits related to Indosinian ophiolites; (3) Indosinian sedimentary-reformed type Fe-Cu polymetallic deposits; (4) Yanshanian W-Sn-Mo-Cu polymetallic deposits related to intermediate-acid magmatic rocks; (5) Yanshanian hydrothermal vein-type Pb-Zn polymetallic deposits; (6) Himalayan MVT-type Pb-Zn polymetallic deposits. For each metallogenic series, the metallogenic geology and genetic mechanism of a selected typical deposit have been introduced and analyzed. In addition, this paper thoroughly probes into the relationship between regional tectonic evolution and mineralization in the LZMB, and points out that the massive development of various deposits in this belt is the result of long-term evolution of Paleo-, Meso-, and Neo-Tethys. This study is helpful for us to deeply understand the metallogenesis and metallogenic regularity in the LZMB, and offers important referential value for future prospecting and exploration in this belt.
