THE GELASIAN STAGE: A PROPOSAL OF A NEW CHRONOSTRATIGRAPHIC UNIT OF THE PLIOCENE SERIES

Rivista Italiana di Paleontologia e Stratigrafia, 2017
A new Stage, the Gelasian, is proposed as the third upper subdivision of the Pliocene Series. The GSSP of the base of the Gelasian Stage and of the Middle Pliocene-Upper Pliocene boundary is coincident with a "sapropel" level which outcrops in the Monte ...

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.

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

The Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Unravelling upbuilding pedogenesis in tephra and loess sequences in New Zealand using tephrochronology [PDF]

, 2010
The genesis of soils developed in either tephra or loess on stable sites differs markedly from that of soils developed on rock because classical topdown processes operate in conjuction with geological processes whereby material is added to the land ...

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

BRACHIOPODS FROM THE TYPE-SECTION OF THE BITHYNIAN SUBSTAGE (ANISIAN, MIDDLE TRIASSIC, NORTHWESTERN TURKEY)

Rivista Italiana di Paleontologia e Stratigrafia, 2016
The Bithynian substage of the Anisian stage (Middle Triassic) was established by Assereto in the Gebze area (Kocaeli peninsula, northwestern Turkey), within the middle member of Nodular Limestone formation, now included in the Tepeköy Formation. The rich

Seismic Stratigraphy of Eocene–Recent Mixed Depositional Systems on the SE New Zealand Continental Margin, Great South Basin

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.
