The north Qilian area is one of important metallogenic belt of China,and it is composed of microcontinent,ophiolite,mélange belt,ocean ridge and ocean island volcanic rocks,island arc volcanic rocks and island arc sediment rocks.The ore-forming elements of Au,Cu,Fe,Mn,As,Sb,Ba, Cr,Ni,Co and V are strong enriched in the metallogenic belt.The geochemical block theory and method have been applied to research the distribution characteristics and metal resources potential.Utilizing classification of blocks,internal structure and serials of blocks are established to form relevant geochemical model,in order to search for processes of gradual enrichment of mineralizing elements.By using the geochemical block and regional geological background,ore-forming potentiality of the main metallogenic elements of Au,Cu,Cr,Ni,W and Sb is analyzed.Ore-bearing potentials of different geochemical blocks in the north Qilian ogogen are evaluated.
