Scope The Lower-Middle Pleistocene Boundary GSSP, which is placed to be around the Matuyama-Brunhes boundary, is going to be ratified in 2015. Three candidates (Montalbano Jonic, Valde di Manche and the Chiba Section) have been proposed so far. The aim of this session is to facilitate GSSP ratification at the Chiba Section through discussion for stratigraphic, chronologic and sedimentological studies regarding with the Mid Kazusa Group.
