The Lower belongs to the Miocene and is petroliferous, while the 

 Upper belongs to the Pliocene. The Neogene in the vicinity of Nagoya 

 and Yokkaichi is noted for its lignite-seams, althongh only of a local 

 importance. The Tertiary on the eastern and southern coasts of 

 Kii Peninsula is of the Miocene and Pliocene ages, while that on 

 the western coast is Pliocene. The Tertiary strata on the southern 

 coast of Shikoku Island seems mostly to represent the Pliocene. 



The Neogene formations scattered in the Chugoku district ranges 

 between the Miocene and the Pliocene, the Coal-bearing Series of the 

 Ube coal-field and the Shinji Series of Izumo being regarded probably 

 as Miocene. The Tertiary found in the southern part of Ivytishu 

 Island belongs to the Neogene, comprising the Miocene and the Pliocene, 

 whereas that of the northern part is of the Palaeogene, forming 

 important coal-fields as already described. 



In the Tertiary of Ogasawara-jima, Kytikyti and Taiwan, certain 

 strata containing Miocene forms of foraminifera are known to occur, 

 together with the Eocene NummuUtes beds. The Neogene of Taiwan 

 is coal-bearing in the north, while it is petroliferous in the south. 

 The Tertiary of Hokkaid5 is usually divided into four parts ; the 

 Lower, the Middle, the Upper and the Uppermost. The Lower is the 

 coal-bearing Palaeogene and the other three range between Miocene 

 and Pliocene or Pleistocene. The Middle Tertiary consists of the 

 Poronai Series in the lower part and the Kawabata Series in the 

 upper, with a transitional formation, the Momiji-yama Scries, 

 between. The upper Tertiary is often petroliferous and its rocks 

 resemble those of the jjetroliferous formation of northern Honshii. 



(2) Quaternary. 



The Pleistocene deposits occupy an extensive area in central 

 Saghalien, eastern Hokkaido, central Honshu, central and southern 

 Kyu?hu and western Taiwan. Their chief elements are loose sand, 

 gravel, clay, pumice and loam, which interstratify with one another, 

 and form elevated plains as well as coastal and river terraces. 



Eaised coral reefs are found on the islands of Ogasawara-jima 

 (Benin), Ptytikyii and Taiwan. They usually form terraces or table- 

 lands and are easily distinguishable from the Recent ones by the 

 difference in height, indurated character and secondary colouration.
