Geography
Country:New Zealand State/province:Chatham Islands
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
