Stratigraphy
Geological group:Tokarahi Formation:Tapui Glauconitic Sandstone Member:Gardiner Greensand
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Incholme Glauconitic Sand Mbr of the Tapui Glauconitic Sand Fm, immediately overlying the Kauru Fm (Teurian), and overlain locally by Raki Siltstone (Kaiatan). AGE: upper Bortonian of Gage (1957) = Bartonian. STRATIGRAPHIC POSITION: From upper member within the formation.
Lithology and environment
Primary lithology:fine,glauconitic,micaceous lithified calcareous,carbonaceous sandstone
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Fine calcareous micaceous sand, with fine glauconite and unusually fine, disseminated carbonaceous material. LITHIFICATION: Presumably lithified, based on facies description (detailed in Gage 1957), taphonomy, and age.
Environment:offshore
Geology comments: ENVIRONMENT: Deposited in still water beyond reach of strong wave action.
Taphonomy
Modes of preservation:body,cast,mold/impression,concretion
Degree of concentration:dispersed
Size of fossils:macrofossils
Abundance in sediment:common
Collection methods and comments
Collection excludes:all microfossils
Collection methods:selective quarrying,field collection
Reason for describing collection:biostratigraphic analysis
Museum repositories:IGNS
Collection method comments: COLLECTOR: Collected by various authors, which may include: Marwick (1924-1944), Laws (1930-1941), and Powell (1942). REPOSITORY: New Zealand Geological Survey (now GNS Science, Lower Hutt, New Zealand).
Taxonomic list comments:COVERAGE: Exhaustive for bivalvia, gastropoda, and brachiopoda. IDENTIFIER: J.A. Marwick and O.P Olson(NZGS). NOMENCLATURE: Somewhat antiquated but identified by specialist and often to subgeneric and species resolution.
