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 ...

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 ...

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 ...

The chronostratigraphy of protoplanet Vesta [PDF]
Icarus, 2014 In this paper we present a time-stratigraphic scheme and geologic time scale for the protoplanet Vesta, based on global geologic mapping and other analyses of NASA Dawn spacecraft data, complemented by insights gained from laboratory studies of howardite–eucrite–diogenite (HED) meteorites and geophysical modeling.

Long-term landscape evolution of the Molise sector of the central-southern Apennines, Italy
Geologica Carpathica, 2017 This paper concerns the reconstruction of the main stages of the long-term landscape evolution of the Molise portion of the central-southern Apennines along a transect divided into three sectors (SW, Central and NE).
