| An Analysis of Tectonic Stress Field and Prospecting Direction in the Gaoshan Gold and Silver Deposit, Longquan Area, Zhejiang Province |
| Located in Suichang–Longquan area, the Gaoshan gold and silver deposit is a typical volcanic-subvolcanic meso-epithermal deposit with its mineralization closely controlled by fault activities. This paper mainly presents field measurements of joints and faults for identifying features of activities and the principal stress direction by using traditional methods in tectonic stress field research. Stages and times of the tectonic stress field are also determined based on deformation and intersection relations with structures and diagenesis ages of strata. The results show that the tectonic stress field in the Gaoshan gold and silver deposit can be divided into six periods. Basement structural deformation occurred before the metallogensis. Ore-controlling fault activities and main mineralization could be divided into two periods, and gold and silver orebodies were locally dislocated by fault activities after the formation of the ore deposit. Present prospecting progress and characteristics of different phases of tectonic activities are additionally discussed; on such a basis, the authors hold that much attention should be attached to the depth in further ore prospecting. |
