Principal geologic and tectonic events and mineralization in the northern margin of the North China Craton

The northern margin of the North China craton has abundant supplies of multi-metal resources. The mineralization mainly occurred in four different geological times, which corresponding with the principal geologic and tectonic events. They are as follows: (1) 1800 Ma for the formation of the banded iron, gold, copper-zinc in the greenstone rocks, and lead - zinc mineralization in metasediments; (2) 800 Ma for the lead - zinc - copper and REE (iron) deposits in the submarine volcanic sedimentary rocks, as well as the mafic - ultramafic magmatic vanadium - titanium - magnetite deposits; (3) 280 - 340 Ma for the porphyry gold-copper (molybdenum) deposit, mafic ultramafic magmatic copper - nickel deposit; gold deposit in ductile shear belt; and (4) 130 - 180 Ma for the skarn copper deposits, lead-zinc deposits; lode gold, silver, lead-zinc and copper deposits by hydrothermal process, porphyry copper - molybdenum deposit, altered and lode gold deposits.
