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=Ypresian-Bartonian age based on biostratigraphy from combination of faunal groups. The particular collection is dated as Late Waipawan=early Ypresian. |
Lithology and environment
Primary lithology: | shelly/skeletal,white poorly lithified calcareous grainstone |
Includes fossils? | Y |
Lithology description: Soft, white, poorly-bedded bryozoan-echinoid-foraminiferla-bivalve rich packstone | |
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). |
