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.
