Stratigraphy
| Formation: | Shimajiri | Member: | Yonabaru Clay | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The Yonabaru Clay includes all Shimajiri Formation exposed below the upper tuffaceous pumiceous zone. The Yonabaru consists of bluish to gray silty to sandy clay, commonly with hackly to conchoidal fracture and fine dark-colored laminated to massive sand, weathering brown to gray, and in places contains large lime indurated concretions of sand. Most macrofossils are found in sandy beds intercalated with the clays. The Yonabaru passes under the cover of the basal gravels of the Naha limestone, and lap onto or are faukted against Paleozoic basement rocks. | |||||
Lithology and environment
| Primary lithology: | poorly lithified silty,sandy claystone |
| Secondary lithology: | planar lamination,concretionary,brown,gray sandstone |
| Includes fossils? | Y |
| Includes fossils? | Y |
| Lithology description: Bluish to gray silty to sandy clay, commonly with hackly to conchoidal fracture and fine dark-colored laminated to massive sand, weathering brown to gray, and in places contains large lime indurated concretions of sand. | |
| Environment: | deep-water indet. |
| Geology comments: Molluscs found in assemblages of the Yonabaru Clay indicate moderately shallow to moderately deep water. Probably a depth of less than 100 fathoms in shallow facies and probably not more than 300 fathoms in deeper facies. | |
