| Structural Features and Ore-controlling Role of Major Fracture Zones in the Fuxin Gold-Polymetallic Ore-forming Area, Western Liaoning |
| The major fracture zones in the gold-polymetallic ore-forming area in Fuxin, Liaoning Province, were studied by analyzing macrostructural features, microstructural deformation and tectonogeochemistry. The basic features of these zones and their control over the ore-forming process are discussed in this paper. The authors point out that the NEE-and the NNE-trending ductile-brittle shear zones are the major structures serving as the controlling factor and the passageways for fluids in the gold-forming district of Fu-xin area, and that the NW-trending faults and the EW-trending faults, which are the second-order faults in the NEE-and the NNE-trending faults, are important host structures along which the present explored gold orebodies are distributed. |
