矿区东部断裂呈弧形弯曲，并作NNW向收敛、SE方向撒开趋势，这些弧形断裂应是一帚状构造。
In the east part of the orefield, the trend of arcual fault is convergent NNW-wards and divergent SE-wards. These arcual faults must be a broomlike structure.

Fig. 2 Anterior-posterior border deossification behind L5 of lumbar with PLMN, arcuated bone block was bilateral faulting and palinal, the right crypt and spinal canal were stenotic.
矿体产出形态及空间分布，严格受近南北向弧形张扭性断裂控制。
The morphology and spacial distribution of the ore body are strictly controlled by the N-S arc-shaped tensional and torsional fractures.
