Stratigraphy
Geological group: | Kaierero | Formation: | Rifle Butts | ||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Rifle Butts Fm, which gradationally overlies the Gee Greensand of the Kaierero Group, and is overlain by the Kurow Group. AGE: Hutchisonian-Awamoan in text of Gage (1957); late Altonian = Burdigalian-earliest Langhian; hereby assigned to the Altonian. STRATIGRAPHIC POSITION: Unknown position within the unit. |
Lithology and environment
Primary lithology: | glauconitic,shelly/skeletal,gray,green poorly lithified sandy claystone |
Includes fossils? | Y |
Lithology description: SPECIFIC LITHOLOGY: "Sandy clays"; fine, glauconitic, greenish-grey sandstone containing brachiopods and molluscs grading up to a fine silt or mudstone. Concretionary bands and layers of tabular concretions indicate bedding in otherwise unstratified sediment. Fossils are disseminated through the silt, and also entombed in concretions and concentrated in shell-limestone lenses. LITHIFICATION: Poorly lithified, largely assumed, as no indication is given text of lithification state, except that concretionary layers are contrasted with the background lithology. | |
Environment: | coastal indet. |
Glacial or sequence phase: | transgressive |
Geology comments: ENVIRONMENT: Shallow marine, siliciclastic. Increasingly rapid accumulation of sediment in deepening water. |
Taphonomy
Modes of preservation: | body,concretion |
Degree of concentration: | concentrated |
Size of fossils: | macrofossils |
Abundance in sediment: | common |
Collection methods and comments
Collection methods: | selective quarrying,field collection |
Reason for describing collection: | biostratigraphic analysis |
Museum repositories: | IGNS |
Collection method comments: COLLECTOR: Collected by Park (1915-1916). REPOSITORY: New Zealand Geological Survey (now GNS Science, Lower Hutt, New Zealand). | |
Taxonomic list comments:COVERAGE: Exhaustive for bivalvia, gastropoda, and polyplacophora. IDENTIFIER: Identifications compiled from previously published accounts and reassessments of NZGS collections, by various paleontologists. NOMENCLATURE: Somewhat antiquated but identified by specialist and often to subgeneric and species resolution. |
