Metallogenic Characteristics and Prospecting Target in the Qilian Metallogenic Zone

On the basis of a synthetic analysis of ore-forming conditions and regional mineralization characteristics in the Qilian metallogenic zone, it is proposed that marine volcanic, contact metasomatic (skarn), meta-sedimentary (including sedimentary exhalative) and ductile shear zone types are the major target oredeposits in the zone.By means of study on geology and ore deposits as well as geophysical, geochemical exploration and remote sensing, 69 prospecting areas have been located.Among them, 5 areas are grade A, 23 areas grade B and 41 grade C, and 16 copper, lead, zinc, gold and tungsten target areas for mineral resource assessment have been selected.
