| Abstract: | The principal strata exposed in the central sector of the Da Hinggan Mountains are the Permian marine volcanic sedimentary series,which constitutes the main host rocks of copper polymetallic deposits.It has higher abundances of the ore forming elements Cu,Pb,Zn,Ag and Sn and thus is the important source of major ore forming substances.The spatial temporal distribution of different deposit types is closely related to the Early Permian tectonic sedimentary environment. |

| Keywords: | central sector of the Da Hinggan Mountains Permian abundance of ore forming elements source of ore substances |
