The Honam Shear Zone, an important feature in the Phanerozoic geologic history of Korea, has attracted much attention due to its potential tectonic significance. However, little has been known about the displacement amount of the shear zone. Here, we propose a possible displacement marker for the shear zone. The geographic position and peculiar lithology of the Sancheong and Gaya anorthosite bodies in the south-central part of Korea suggest a NE-trending dextral strike slip shear zone that has a displacement of ca. 50 km. This hypothetical shear zone is considered as a part of the Honam Shear Zone since the former has the same trend and shear sense as the latter.
