The precious metallogenic belt and its geoloqical-tectonic location in eastern China._x000D_
The precious metallogenic belt of eastern China is located in the western part of the Pacific gold metallogenic belt, and occurs in the upper levels of the continent cut by a deep fault structure tending NNE and NE, and active during the Mesozoic. The precious metallogenic period ranges mainly from Late Jurassic to Early Cretaceous (160 Ma-110 Ma); subordinate mineralisation occurred during the Hercynian period, and was rare in the proterozoic._x000D_
Seven precious metallogenic belts are recognised from east to west, i.e. from continent to the margin active belts, as follows: 1. Au-Ag-Te metallogenic belt of East Shandong Province 2. Au-Ag-Pb-Zn metallogenic belt of west Liaoning-Miyun area 3. Au-Os-Ir-Cr-Cu Mo metallogenic belt of Chengde Pingquan area 4. Au-Ag-Pb-Zn metallogenic belt of Zhang Xuan area 5. Au-Ag-Pb-Zn metallogenic belt of Zhejiang province 6. Au-Ag-Se metallogenic belt of East Qinling area 7. Au-Pd-Cu-Mo metallogenic belt of Wansu area
