摘要
Gongchangling iron deposit is in large size and discovered earlier with a long mining history.To depth ore gets rich.Structural analysis shows that the second mining district was exposed to,at least 4 deformation episodes.The first episode is small plastic flowing deformation of folds,the second episode regional inverted isoclinal folds,the third episode cross overprinting fold,the fourth regional uplift.The four episodic deformations were accompanied by ductile shear zone which is characterized by ductile shear zone-brittle-ductile zone-ductile-brittle zone-brittle fractural zone from early to late.The deformation shows a certain control on formation of the iron ore.
