Stratigraphy
Formation:Futuna Limestone
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Futuna Limestone, which overlies the Lau volcanics (?Early-Middle Miocene), and are overlain by the Koro Mbasanga volcanics (?Late Miocene). AGE: Lower Miocene according to Ladd (1945), and stage "f" of Van der Vlerk. Ladd's age is based on lyellian percentages so should be treated with caution. Lad (1966, 1972, 1977, 1982) appear to suggest a Middle Miocene age, which is adopted here. STRATIGRAPHIC POSITION: Basal foraminiferal limeston.
Lithology and environment
Primary lithology: lithified "limestone"
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Foraminiferal limestone. LITHIFICATION: Presumed lithified, as stated to be limestone, hill capping, and with limited diversity.
Environment:carbonate indet.
Geology comments: ENVIRONMENT: Unknown environment, though presumably shallow water carbonate.
Taphonomy
Size of fossils:macrofossils
Collection methods and comments
Collection methods:field collection
Reason for describing collection:biostratigraphic analysis
Collection method comments: COLLECTOR: H.S. Ladd and E.J. Hoffmeister, presumably with others. REPOSITORY: Unknown, possibly the Bernice P. Bishop Museum, Honolulu, Hawaii, or the USNM.
Taxonomic list comments:COMPLETENESS: Exhaustive for echinoidea, gastropoda, bivalvia, bryozoa, brachiopoda, and decapoda. NOMENCLATURE: Authoritative publication, although somewhat antiquated. Regular use of subgenera and species level identifications. Nomenclature vetted by A. Hendy (1/2007).
