From the foregoing it is beyond dispute that what underUes the 

 hill of Ciiigasaki is a demolished block of a small igneous body 

 structurally independent of the somma body.

The easterly lyuig Kazahaya'^ (la), a hill with a height of 108 ?»., 

 is also underlain by a demolished igneous body (Fig. 27). It consists 

 of lavas (petrographically somewhat difterent from those of Chigasaki, 

 but also rich in ohvine) and éjecta, dipphig also toward the sea, 

 and having a structure like that of Chigasaki (PL VI. GA). 



To the east of Kazahaya other small igneous bodies of olivine- 

 rich basaltic and doleritic rocks in the form of lavas and intrusives 

 are found (PL VI. GA 10 — 11). They are overlain by layers of 

 contemporaneous éjecta, over the denuded surface of which later 

 materials of the somma are again spread. 



Another ruined igneous body (PL VI. GA 9) lies to the 

 west of Okata'^ (•2a). This consists of many thin layers of 

 lavas (olivine-bytownite-basalt) and éjecta. What is considered
