Meso-scale faults are investigated for reconstruction of paleostress recorded in the Shimajiri Group during the upper Miocene to lower Pleistocene exposed around southern region of Okinawa-jima (island). Stress field was estimated by means of the stress inversion method. Every fault slip data from the three formations, namely Tomigusuku, Yonabaru and Shinzato Formation, were calculated. The datasets were divided into subgroups by means of histogram which drew angular misfits between observed and predicted slip directions. Newly calculated stresses are classified by the axial directions and stress ratios. As a result, four stress states were obtained for the Shimajiri Group. Stress state A is NW-SE extension, B is NE-SW extension, C is E-W extension and D is strike-slip type. The order of stress state is C and D, B, A from older to newer. These stress states can be interpreted as a result of subduction of the Philippine Sea plate beneath the Eurasia plate and the crustal extension in the Okinawa Trough. |
