Stratigraphy
Geological group: | Alma | Formation: | Totara Limestone | Member: | Weston |
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: STRATIGRAPHIC RELATIONS:From Weston Mbr of the Totara Limestone, which overlies the Waiareka Volcani Fm (Kaiatan), and overlain locally by Deborah Volcanic Fm (Whaingaroan). AGE: Runangan of Gage (1957) = Priabonian. STRATIGRAPHIC POSITION:Unknown position within formation. |
Lithology and environment
Primary lithology: | shelly/skeletal,gray,yellow poorly lithified "limestone" |
Includes fossils? | Y |
Lithology description: SPECIFIC LITHOLOGY: Soft grey or pale greyish-yellow polyzoan limestone. LITHIFICATION: Poorly lithified, based on facies description (detailed in Gage 1957), taphonomy, and age. | |
Environment: | reef, buildup or bioherm |
Geology comments: ENVIRONMENT: Reef, founded on a volcanic sea mount rising abrupt from comparitively deep water to within reach of the sorting and winnowing action of waces and shallow enough to be colonized by polyzoans, brachiopods, and molluscs. |
Taphonomy
Modes of preservation: | body,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 C. Laws(NZGS). NOMENCLATURE: Somewhat antiquated but identified by specialist and often to subgeneric and species resolution. |
