A series of paleogeographic maps of the Japanese Islands, from their birth at ca 750700 Ma to the present, is newly compiled from the viewpoint of plate tectonics. This series consists of 20 maps that cover all of the major events in the geotectonic evolution of Japan. These include the ...
thus suggesting that the Kibi Plateau has been a stable-coherent tectonic unit since the Eocene through the opening of the Japan Sea and the associated quick rotation (an angular velocity of 20°/Myr) of SW Japan that took place in the Middle Miocene7,8. Its average uplift rate...
Fig. 1. Geological map of the Aki area in the Northern Shimanto Belt, Kochi Prefecture, southwest Japan (modified from Taira et al., 1988). Abbreviations: M.T.L. = Median Tectonic Line; T.L. = Tectonic Line. The Aki umber deposit occurs in the Tei mélange, which was mined from 19...
The Izu-Bonin arc lies along the convergent boundary where the Pacific Plate subducts beneath the Philippine Sea Plate. Horizontal velocities of continuous... DHK Arisa - 《Tectonophysics International Journal of Geotectonics & the Geology & Physics of the Interior of the Earth》 被引量: 0发表...
The maximum uplift during the Quaternary is estimated to be approximately 1700 m in the Hida Range (Research Group for Quaternary Tectonic Map, 1968). However, it is generally difficult to accurately date the surface and to estimate the initial elevations of the surfaces. In addition, low-...
Figure 1 presents positions of the network stations and the location of the Nankai Deep Trench, which is the northern boundary of the Philippine tectonic plate. The seismic data with a sampling frequency of 1 Hz were reduced to a time step of 1 minute by calculating the mean values in ...
