Relationships between the major geologic structures and active fault system in the Mino-Tanba Belt, central Japan.

本文研究了滋贺北方和福井县南部沿着柳濑活动断裂及其北方延带的新构造结地区侏罗纪增生体的明显走向摆动。其周围的走向摆动形成了具有南北向铰合面和垂向倾伏铰合轴的扭折（巨扭折）或人字形褶皱。在北方，走向摆动由较小规模的垂直轴褶皱组成，在南方，柳濑断层沿着半波长约10 km的紧密闭合走向摆动的枢纽面。因此，柳濑断裂的形成与美浓-丹波带地层的突然走向变化密切相关。本文详细研究了丹波带中的六甲罗尔特系和三户-户田断裂，美浓带和柳屋带中的饭田-松川断裂和坂户-神谷断裂的基底构造、构造地形和断层岩组沿着。结果表明，这些结构要素不仅对研究活动断裂的历史，而且对揭示断裂的物理条件和位移方向都是非常重要的，利用结晶度指数标准（CIS）样品对伊利石结晶度数据的标准化进行了检验，以评价增生杂岩的热历史。结果表明，CIS的标准化是一个基本的程序比较IC数据测量由不同的laborators.The中生代Torlesse地体在新西兰南岛的结构分析，表明，先前存在的增生相关的结构强烈修改的新近纪的干扰。次级变形的特征与美浓-丹波带的特征相似，表明围绕中等至垂直倾伏旋转轴的走向摆动是增生沉积为主的碎屑岩的基本构造过程。

The distinct strike-swings of the Jurassic accretionary are studied in the Neo Syntaxis area along the Yanagase active fault and its northern extention in the northern Shiga and southern Fukui Prefectures. The strike-swings around there were formed as kink-like (megakink) or chevron folds with N-S trending hinge surface and verticaly-plunging hinge axis. In the northern part, the strike swings are composed of smaller-scale folds with vertical axes, and in the southern part the Yanagase Fault occupies along the hinge surface of the tightly closed strike-swing about 10 km in half-wavelength. Hence, the origin of the Yanagase fault was intimately related to the formation of the sudden strike-change of the strata of the Mino-Tanba BeltThe basement structures, tectonic topographies and fault-rock fabrics along the Rokko Rault system and Mitoke-Tonoda fault in the Tanba Belt, and the Iida-Matsukawa and Sakaitoge-Kamiya fault in the Mino and Ryoke Belt are precisely studied. As the results, it has clarified that these structural elements are very important not only to solve the history of active faulting but also to reveal the physical conditions and displacement sense of faulting.Standardization of illite crystallinity data were checked by using the Crystallinity Index Standard (CIS) sample to evaluate the thermal history of the accretionary complex. The results suggest that the CIS standardization is a fundamental procedure for comparison of the IC data measured by different laboratories.The structural analyses of the Mesozoic Torlesse Terrane in South Island, New Zealand, suggest that the pre-existing accretion-related structures were strongly modified by the Neogene disturbances. The features of the secondary deformations are comparable to those of the Mino-Tanba Belts, suggesting that the strike-swings about the moderately to vertically plunging rotation axes are fundamental structural process of the accretionary sediment-dominated terrane.
