Geography

Coordinates: | 44.3° South, 176.8° East (view map) | ||
Paleocoordinates: | 54.5° South, 155.4° West | ||
Basis of coordinate: | estimated from map | ||
Geographic resolution: | outcrop |
Time
Period: | Paleogene | Epoch: | Eocene |
Stage: | Ypresian | 10 m.y. bin: | Cenozoic 2 |
Key time interval: | Waipawan | ||
Age range of interval: | 56.00000 - 52.00000 m.y. ago |
Stratigraphy
Geological group: | Kekerione | Formation: | Te Whanga Limestone | Member: | Matanginui Limestone |
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: THICKNESS: Matanginui Limestone is approximately 25 m thick at the type section. STRATIGRAPHIC RELATIONS: Matanginui Limestone is the lower member of the Te Whanga Limestone and conformably overlies the Red Bluff Tuff, and is unconformably overlain by younger strata. AGE: It is assigned an Waipawan-Bortonian local stage=Thanetian-Bartonian age based on biostratigraphy from combination of faunal groups. The particular collection is dated as Late Waipawan=Ypresian. |
Lithology and environment
Primary lithology: | shelly/skeletal poorly lithified calcareous grainstone |
Includes fossils? | Y |
Lithology description: Soft, bryozoan-calcarenite. | |
Environment: | offshore |
Geology comments: Molluscan assemblages suggest warm, relatively shallow-water, undoubtfully oceasnic, with moderately deep water for part of the time (probably beyond shelf edge). |
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 |
Collection method comments: Collections reposited in Institute of Geological and Nuclear Sciences (New Zealand Geological Survey) collections. Collected by MAC (1977) | |
Taxonomic list comments:Exhaustive for all faunal groups. Identified by P.A. Maxwell, D.E. Lee, J.S. Buckeridge, I.W. Keyes, and R.F. Jenkins. |
