Anatomy and origin of authochthonous late Pleistocene forced regression deposits, east Coromandel inner shelf, New Zealand: implications for the development and definition of the regressive systems tract [PDF]

open access: yes, 2004
High-resolution seismic reflection data from the east Coromandel coast, New Zealand, provide details of the sequence stratigraphy beneath an autochthonous, wave dominated inner shelf margin during the late Quaternary (0-140 ka). Since c.

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]

open access: yes, 2001
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

Zur Gliederung der Holstein- und Saalezeit im östlichen Harzvorland [PDF]

open access: yesEiszeitalter und Gegenwart, 1965
A review is given on the results of researches which were undertaken in the Pleistocene of the eastern foot-hills of the Harz. A terrace could be detected where the gravels have been accumulated during a cold period in the Holstein stage.

An integrated biostratigraphy and seismic stratigraphy for the late Neogene continental margin succession in northern Taranaki Basin, New Zealand [PDF]

open access: yes, 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 ...

A drilling data-constrained seismic mapping method for intermediate-mafic volcanic facies

open access: yesPetroleum Exploration and Development, 2016
Based on 112.5 km2 of 3-D seismic data and data of 8 prospecting wells drilled volcanic rocks in the 3rd member of the Paleogene Shahejie Formation in Hongxing area of the Eastern Sag of the Liaohe Depression, Bohai Bay Basin, three levels of volcanic ...

Pliocene and Pleistocene chronostratigraphy and paleoenvironment of the Central Arctic Ocean, using deep water agglutinated foraminifera [PDF]

open access: yes, 1998
Deep-water agglutinated foraminifera (DWAF) were studied from Cores PS2177-5, PS2200-5, PS2212-3 and PS2185-6; from the R/V POLARSTERN ARK-VIII/3 Cruise in the central Arctic Ocean.

The different approaches in seismic stratigraphy interpretation [PDF]

open access: yesTehnika, 2018
This paper presents two basic approaches in seismic stratigraphy interpretation. The first one as starting point have seismic sections, whose interpretation in the later stage correlates with well data.

The GSSP Method of Chronostratigraphy: A Critical Review

open access: yesFrontiers in Earth Science, 2018
The use of boundary stratotypes to define chronostratigraphic units began in the 1960s, and, in the 1980s, these were called Global Stratotype Sections and Points (GSSPs). Approximately two-thirds of the GSSPs of the bases of the Phanerozoic stage (71 of

The Palaeolithic sequence of the Arma dell’Aquila (Finale Ligure, Savona, North-western Italy)

open access: yesMateriale și Cercetări Arheologice, 2021
The excavations carried out in the rock-shelter of Arma dell’Aquila by C. Richard in 1938 and 1940 led to the discovery of a thick stratigraphy, the lowermost deposit of which yielded evidence of different periods of Upper Palaeolithic occupation.

An origin of ultraslow spreading ridges for the Yarlung-Tsangpo ophiolites

open access: yesFundamental Research, 2022
As relics of ancient ocean lithosphere, ophiolites are the most important petrological evidence for marking the sutures and also play a key role in reconstructing plate configuration.
