Local section: | Maccoyella Ridge | Local bed: | 80 ft | ||
Local order: | bottom to top | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Koranga Sandstone of the Taitai Series, overlies Torelsse supergroup along Maccoyella Ridge and is unconformably overlain by the the Te Wera Sandstone. THICKNESS: From bed within formation that varies in thickness between 116 (at this area) and 76 m (locally). AGE: Korangan of Wellman (1956) = Upper Aptian based on presence in unit of Aucellina radiatostriata and Maccoyella reflecta (Day 1969, Day and Speden 1970). STRATIGRAPHIC POSITION: From 80 ft above base of unit. |
Lithology and environment
Primary lithology: | fine,pebbly lithified sandstone |
Includes fossils? | Y |
Lithology description: SPECIFIC LITHOLOGY: Hard, non-calcareous pebbly fine sand. LITHIFICATION: Lithified, based on facies description. | |
Environment: | coastal indet. |
Glacial or sequence phase: | transgressive |
Geology comments: ENVIRONMENT: Accumulated in shallow-water, high-energy environment. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Collection methods and comments
Collection methods: | selective quarrying,field collection |
Reason for describing collection: | biostratigraphic analysis |
Museum repositories: | IGNS |
Collection method comments: COLLECTOR: I.G. Speden. REPOSITORY: GSNZ (now GNS Science, Lower Hutt, New Zealand). | |
Taxonomic list comments:COVERAGE: Exhaustive for bivalvia, and other invertebrate groups (cephalopoda, gastropoda, echinoidea, bryozoa, annelida listed). NOMENCLATURE: Not an authoritative publication, and generally lacking species-level designations. Identified by specialist (Speden), and lack of species names reflects poor preservation and insufficient existing taxonomic knowledge. |
