Fig. 1From: An improved apparent polar wander path for southwest Japan: post-Cretaceous multiphase rotations with respect to the Asian continenta Tectonic outline map of East Asia and the Japan Arc. Kk: Kita-Kyushu area; O: Onogawa area; Si: San’in area; iZ: Izumi area; iN: Inakura area (study area); iK: Ikuno area; Sy: Sasayama area. Bx: Benxi area; Na: Ning’an area. MTL represents the Median Tectonic Line that demarcates southwest Japan into the inner and outer arcs. MF denotes the Mudanjiang Fault, which is considered to be the northern boundary of the Paleogene clockwise rotation (Huang et al. 2007). b Previously reported 110 Ma paleomagnetic poles for East Asia and southwest JapanBack to article page
