Metallogenic geochemistry of Sb-mineralization in southern margin of North China platform

摘要

The Sb mineralization zone in the south margin of North China platform is located int he transitional edge of North China plate and Yangtze plate, belonging to Qinling fold system, whose tectonic line is in NWW-SEE direction regionally. Because of the huge compression caused by the collision of the two plates, the rocks undergone strong deformation and metamorphism have very complicated structures. The regional deep fault- Shuanghuaishu fault - controls Sb-mineralization zone belt, and all the Sb-ore deposits or mineralized spots appear alone at the very southern margin of the fault.
