By applying plate tectonic theory, this paper interprets characteristics of magnetic fields in eastern Qingzang plateau, and indicates the existence of five minerogenic belts (provinces)with different characteristics in this region, whi ch are in turn Kangdian rift minerogenic belt. Longmenshan paleo-are mine rogenic belt, Yarlungzangbojiang paleo-oceanic ridge minerogenic belt, Jinshaji-ang-Ailaoshan block separation-combination minerogenic belt and Bayanhar-shan alongjiang rejuvenated continental crust minerogenic province. Among them,the Kafigdian rift belt contains extremely peculiar and rich ore resources, such as world-famous V, Ti, Ni, Pt ores, Au, Cu, Pb, Zn ores, REE, Sn and oth er polymetallic ores, together with abundant coal, P, gypsum halite and oil-gas resources, thus making up a minerogenic belt with the largest ore reserves and the most complicated mineral species in China. The Yarlungzangbojiang minerogenic belt is actually the eastern extension part of the main belt of the world-famous Mediterranean chromite belt, hence being the most promisng area for chromite resources in China.The Jinshajiang-Ailaoshan minerogenic be-It has its special, structures and contains various sorts of nonferrous and noble metal ores, such as Au-bearing and Ag-rich polymetallic ores and porphyry copper deposits, with the mineralized outcrops often stretching uninterrupted ly for several hundred kilometers, suggesting its considerable economic poten tial.Finally, the present paper gives a discitssion on mineralization model of the plateau minerogenic belt and the effectiveness of geophysical prospecting in this belt. It is suggested that ore prospecting work should be conducted in seven important ore belts (provinces).
