Metallogenic Regularity and Minerogenetic Series of Ore Deposits in Inner Mongolia and Adjacent Areas
详细信息   
摘要


     In this paper, based on the new understanding of tectonic evolution of Inner Mongolia, the new progresses in geosciences of its adjacent areas, especially a large number of precise mineralization ages data, and the new understanding of the sources of rock-forming and ore-forming materials, the authors divided the ore deposits in Inner Mongolia into 11 metallogenic series: 1) the Archaean Anshan type metamorphic sedimentary iron deposit metallogenic series(consisting of the Middle Archaean and the Late Archaean series); 2) the Middle Proterozoic submarine exhalative type lead-zinc-copper-sulfur deposit metallogenic series; 3) the Mesoproterozoic Bayan Obo REE-Fe-Nb deposit metallogenic series; 4) the Ordovician-Silurian porphyry copper deposit metallogenic series; 5) the Devonian ophiolite related chromite deposit metallogenic series; 6) the Late Permian-Triassic granite related molybdenum-gold polymetallic deposit metallogenic series; 7) the Triassic-Middle Jurassic porphyry copper deposit metallogenic series; 8) the late Jurassic-Early Cretaceous granite related epithermal type lead-zinc polymetallic deposit metallogenic series in De’ erbugan area; 9) the late Jurassic-Early Cretaceous granite related lead-zinc-tin-molybdenum-gold polymetallic deposit metallogenic series in the Da Hinggan Mountains and adjacent areas; and 10) the Cenozoic lacustrine sedimentary-evaporation related salt deposit metallogenic series.
