| 概要 |
Beard-like veinlet structure is developed in the Neogene tuffaceous siltstone in the Miura Group in the Miura and Boso Peninsulas, central Japan. This structure is constructed by closely spaced dark-c...olored fine grained veinlets. Each veinlet is 0. 2-0. 5 mm in width and 1-5 cm in length. The veinlets occur selectively in much finer and more homogeneous sediments than others, and are disposed usually at high angles and rarely at low angles to the bedding plane. They are apt to develop in sediments around sedimentarily and/or structurally disturbed beds, and often accompany normal faults which were formed penecontemporaneously during the deposition of the Miura Group. Therefore the structure is considered to be formed as an assemblage of fracture cleavages by nearly vertical principal compressive stress in the dewatering process during the development of the sedimentary basin of the Miura Group.続きを見る
