UPPER PERMIAN STRIKE-SLIP UPWARPING AND PULL-APART DOWNWARP OF LEAVE AREA IN BAISHAN SOUTH, GANSU

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.
