[SCG61-P09] Significant of thrust zone at Fuji river basin in the South Fossa Magna, Southern Yamanashi Prefecture, Central Japan
-Study of Structural geology of Minobu and Neguma fault-
Keywords:South Fossa Magna, active faults, Itoigawa Shizuoka Tectonic Line, Fujikawa Kako Fault Zone
Minobu Fault is high probability to connect ISTL and FKFZ in the blank range of active fault. In recent years, it was shown sinistral fault sense from geomorophological point of view.(Mizumoto,2016) Howevere, nortern Minobu Fault is estimated reverse fault sense because of stratigraphy difference.
We discover and described new Minobu fault outcrops and divide Minobu fault into SegmentⅠand Ⅱ. We are obtained datas from stress analysis and XRD analysis in the area.
We will discuss the formation mechanism and history of geological structure deveropment of Minobu and Neguma fault in South Fossa Magna from kinematics of the faults and geological structure.
