| 摘要: |
| Which Continental Block in the East Asian Continental Margin is the Source of the Kurosegawa Terrane? |
| The point at issue: The Kurosegawa Terrane is composed of continental fragments transecting Mesozoic terranes of accretionary complex in Southwest Japan (Fig. 1). It is an attenuated tectonic sliver and considered to be allochthonous with respect to the main part of Southwest Japan. The problem of which continental block in the East Asian continental margin is the source of the Kurosegawa Terrane has puzzled Japanese geologists for many years.
Firstly, we try to approach this issue based on the analysis of fusulinacean assemblage in accreted terranes composed of subduction complex in the Pacific Rim.
Secondly, by applying the result of this analysis we try to locate the source of the continental fragments of the Kurosegawa Terrane.
Thirdly, we try to prove its validity with a new paleomagnetic study. |
