| Abstract: | The Lixian-Minxian foreland basin undertook abyssal-bathyal flysch deposition
at its earlier evolution stage and continental molasse stage at its later evolution stage.Au,Ag,Pb,
Zn,Cu and Mo polymetallic deposits were formed at its foredeep, back-uplift basin and fold-
thrust belts during its forming and the basin-range transformation |

| Keywords: | The Lixian-Minxian foreland basin Structural evolution Polymetallic mineralization |
