| Application of Magnetic Fabric Analysis to the Ductile Deformation Belt in the Tuwu Copper Deposit, East Tianshan, Xinjiang |
| Based on the measurement of 600 km 2 magnetic fabrics in the Tuwu copper deposit, East Tianshan Mountains, Xinjiang, the authors divided the study area into the southern strong ductile deformation domain and the northern weak domain according to va lues of the magnetic anisotropy. The measurement results show that the southern deformation domain is dominated by flasers, while the northern one is characterized by plane strain and contraction strain besides the flasers. It is pointed out that the ductile deformation belt consisting of a series of parallel compressive schistosities is a ductile compressive belt derived from coaxial deformation instead of a ductile shear belt. The Tuwu, Yandong and Linglong copper deposits and the Longxi gold ore spot occur in the local small deformation zones of the northern weak deformation domain, showing the marginal ore forming features in the regional large ductile compressive belt. |
