摘要
Lanjia gold ore field of Changchun area is located in the central part of Daheishan fault uplift, which belongs to the Late Paleozoic to Mesozoic, Batailing-Lanjia precious metals, non-ferrous metals. Lanjia Au, Cu metallogenic province. According to metallogenic geological conditions, geophysical and geochemical characteristics, remote sensing image features and characteristics of the known mineralization in the study area, the authors proposed that these favorable positions, ore-controlling structures and Mesozoic rock bodied made an important controlling role on the gold, polymetal ores, especially Au, Cu mineralization.
