| Abstract: | Ductile shear zone widely developed in Jiaodong region,Shandong province,in which two EW trending zones are giant.Pengjiakuang guanshui ductile zone,which was composed of cataclasites and mylonite,lies in the middle of the south giant zone,It located in the contact between the conglomerates of Laiyang Formation and the metamorphic complex of Late Proterozoic Jinshan Group.The microstructural characteristics and the geological evidence suggest that mylonite in Pengjiakuang guanshui dectile zone formed at strain rate of 11.86, corresponding to differential stress of 262Pa.Chronology studies show that it formed before one thousand million years.Pengjiakuang guanshui ductile zone controls the gold metallization in this region,including the controlling of the ore forming metal elements sources,structural conditions and physical and chemical envirenment of mineralization. |
