The First 40 Million Years of Planktonic Foraminifera
Geosciences, 2021 We provide a biochronology of Jurassic planktonic foramininfera, using first order linkage to ammonite and nannofossil stratigraphy and geochronology. This enigmatic and understudied group of microfossils occurred from middle Toarcian through Tithonian ...

An integrated biostratigraphy and seismic stratigraphy for the late Neogene continental margin succession in northern Taranaki Basin, New Zealand [PDF]
, 2006 Our aim has been to develop an integrated biostratigraphy and seismic stratigraphy for the Pliocene and Pleistocene formations (Ariki, Mangaa, Giant Foresets) in northern Taranaki Basin to better understand the evolution of the modern continental margin ...

The chronostratigraphy of Late Pleistocene glacial and periglacial aeolian activity in the Tuktoyaktuk Coastlands, NWT, Canada [PDF]
, 2006 Aeolian periglacial sand deposits are common in the Tuktoyaktuk Coastlands of Western Arctic Canada. Regionally extensive and thick aeolian sand-sheet deposits have been observed in two major stratigraphic settings: within a sand unit characterized by ...

The Lapland greenstone belt: Stratigraphic and depositional features in northern Finland [PDF]
Bulletin of the Geological Society of Finland, 1987 The Lapland greenstone belt formed in a continental environment, as a result of rifting of the 3.1—3.0 Ga Saamian craton. The basin subsided to a depth of five kilometres between 3.0—2.5 Ga and contains a sequence which is subdivided into Lower, Middle ...

Chronostratigraphy and geochronology: A proposed realignment [PDF]
GSA Today, 2013 We propose a realignment of the terms geochronology and chronostratigraphy that brings them broadly into line with current use, while simultaneously resolving the debate over whether the Geological Time Scale should have a “single” or “dual” hierarchy of units: Both parallel sets of units are retained, although there remains the option to adopt ...
