Stratigraphy
Geological group:Sakishima Formation:Ryukyu Limestone
Local section:F-449
Regional section:Ryukyu
Stratigraphic resolution:bed
Stratigraphy comments: The Ryukyu Limestone unconformably overlies rocks of the Ishigaki Group, the Miyara Formation, the Nosoko Formation, and the Omoto Granite. Two principal lithologies are present - a stratified sandy limestone, and a massive coralliferous limestone. Conglomeratic limestone is common at th base of the formation
Lithology and environment
Primary lithology:planar lamination,brown,yellow poorly lithified sandy,calcareous "limestone"
Secondary lithology:fine,shelly/skeletal lithified calcareous "limestone"
Includes fossils?Y
Includes fossils?Y
Lithology description: The sandy foraminiferal limestone consists of sand sized particles loosely to formly cemented together by calcium carbonate. It is white, light tan or cream. The coralliferous limestone is mostly a well lithified, bioclastic, recrystallized limestone composed of tests or fragments of forams, pieces of corals, pieces of algae, and other types of fossils in a groundmass of fine calcareous organic debris.
Environment:carbonate indet.
Taphonomy
Modes of preservation:body,mold/impression
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:all microfossils,some macrofossils
Collection methods:selective quarrying,field collection
Reason for describing collection:taxonomic analysis
Museum repositories:USNM
Collection method comments: Probably reposited in USGS and USNM collections
Taxonomic list comments:Representative of mollusca. Identified by F.S. MacNeil (mollusca). Corals excluded from list (too many)
