项目摘要
The result of this scientific research is summarized as below.Studies on main active fault systems in the Kinki Triangle region were carried out. There are Rokko-Awaji fault system, Median Tectonic Line fault .system (Wakayama and Tokushima Region), Western and Eastern margin fault system of Kyoto Basin, Hanaore fault system, and Suzuka -Toen fault system and so on. We have carried out geomorphological survey, geophysical prospecting, drilling, trench excavation, and collected the information on deformation mode and subsurface structure along the fault, displacement rate and age for fault activity. Especially, sampling by geoslicer and continuous analysis are shown most recent activities of the faults.Sediment samples from Nohbi Plain, Lake Biwa and Osaka Plain were analysed from the ^<14>C dating and volcanic glass chronology for establishing the chronology of Late Quaternary sediments.Drilling samples by Nojima Fault Prove project indicates vertical displacement during the Quaternary and thermal activity along the fault. Seismic reflection surveys and gravity measurement were carried out crossing the fault traces, and we obtained the information on subsurface structure.We checked the model on the formation of Osaka sedimentary basin on the basis of transcurrent movement of Median Tectonic Line and Arima-Takatsuki Tectonic Line. New method of minor faults analysis was also proposed on the basis of test by artificial data set, and applied to the field data of Quaternary sediments.
这项科学研究的结果总结如下。对近基三角地区主要活动断裂系统进行了研究。主要有六甲- awaji断裂系、中构造线断裂。和歌山和德岛地区断裂系统、京都盆地东西缘断裂系统、花原断裂系统、铃鹿-屯断裂系统等。我们开展了地貌调查、物探、钻孔、挖沟等工作,收集了断层变形模式、地下构造、位移速率、断层活动年龄等信息。特别是地质切片取样和连续分析显示了断层最近的活动情况。利用^<14>C定年和火山玻璃年代学对芦碧平原、琵琶湖和大阪平原沉积物样品进行了分析,建立了晚第四纪沉积物年代学。野岛断裂证明工程的钻井样品显示了第四纪期间的垂直位移和沿断层的热活动。通过地震反射测量和重力测量,获得了断层的地下构造信息。根据中构造线和有马-高月构造线的跨流运动,对大阪沉积盆地的形成模式进行了验证。在人工数据集测试的基础上,提出了小断层分析的新方法,并将其应用于第四纪沉积物的现场数据。
