Description :
This study aims to determine the neotectonic activity of the Manisa Fault and the most recent time of the change in its stress condition through age-dating data obtained by using 230Th/234U dating methodology applied on the calcite coating that develops over hanging-wall of the Manisa Fault and the calcite veins that occur as fracture fillings. Evaluation of the carbonate precipitations on the Manisa Fault along with the age data and the kinematic indicators ascertained that the Manisa Fault switched to a dip-slip normal faulting character from Middle Pleistocene onwards and that the region was under the effect of a NE–SW directional extensional regime. In addition, the opening rate was attempted to be determined using the roll-over anticline structure that advanced depending upon the movement of the fault on the upper horizontal strata of colluviums, which developed in association with the Manisa Fault.
