Stratigraphy of the Upper Pleistocene in the Udo Hills, Shizuoka Prefecture.

Abstract

Stratigraphy and geologic structure of the Late Pleistocene clastic sequence in the Udo Hills, Shizuoka Prefecture, Japan, are described. The hills consist of thick alternating sequence of fluvio-deltaic gravels and shallow marine muddy deposits. The sequence is divided into five formations: the Negoya, Kunosan, Kusanagi, Oshika and Kuniyoshida Formations in upward sequence. The four formations overlying the Negoya Formation constitute a part of a large dome structure. The deformation started after the deposition of the Kunosan Formation. -from English summary
