| 摘 要： | 晚二叠世，处于板内活动中后期的北山南带中段地区，发生规模宏大的左旋位移走滑断裂作用。花牛山-五峰山和黄尖丘-新场两地区形成正性的走滑隆升区，其相应中间地带则显示了负性拉分拗陷作用，发育了大奇山拉分盆地。走滑隆升地区走滑型剪切带发育，为剪切带型的金矿成矿带。拉分盆地以巨厚火山-磨拉石建造为特征，沉积环境为陆相-海相-海陆混合相。

| Abstract: | Upper Permian, large scope strike-slip rift faulting of sinistral rotation displacement happied in Level area of Baishan South in intraplate middle, late active age during Upper Permian. Huanushan-Wufenshan and Huangjianqiu-Xinchang formed positive strike-slip upwarping region, middle belt shown negative down warping, developed Daqishan pull-apart basin. Strike-slip u warping region had well-developed strike-slip type shear zone, it was a shear zone type mineralization belt of golden deposit. Pull-apart basin representative product was volcanic-molasse formation, depositional environment was continental faciesmarine facies-marine, continental mixed fades. |
