| 内容記述 | We report here results of a joint analysis for the Cretaceous Inagawa Granite in northeastern Aichi Prefecture, central Japan. The analysis has been performed as a course of our long-range plan to clarify a genetic link between early formed joints and late-stage faults in granitic rocks, and also in order to understand the joint geometry. The Inagawa Granite is a constituent of the Ryoke Granitoids and can be divided into at least four intrusive units; in this study we call the earliest unit the Obara Granite and the rest the Inagawa Granite (II-IV). Measurement and observation were done at 10 localities. The number of joints observed is 273. Three orthogonal or nearly orthogonal sets of systematic joint were commonly recognized at individual localities; a vertical to steeply dipping set striking NW to NNW, a vertical to steeply dipping NE to ENE-striking set, and a gently dipping set for which the strikes are variable. The gently dipping joint set in the Inagawa Granite (II -IV) probably occurred simultaneously with all the systematic sets in the Obara Granite. Following, vertical or steeply dipping sets may have occurred in the Inagawa Granite (II-IV). These ideas are based largely on the notion that older joint surfaces act as barriers to younger joint propagation, as well as on information about the spacing and spatial continuity of joints. Most likely, all the joints were formed in the Cenozoic. Finally, we suggest that in northeastern Aichi Prefecture, pre-existing systematic joints have played an important role in the generation of active faults in an E-W-trending contractile stress field. | |||||
