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.

Sequence stratigraphy and uranium mineralization model of uranium-bearing rock series in the southern margin of Erlian Basin

open access: yes矿业科学学报, 2018
Based on drilling data, seismic sections and sample test results, the theory of continental to sequence stratigraphy was applied to investigate uranium accumulation of the Early Cretaceous uranium-bearing rock series in the southern margin of Erlian ...

Application of palynological data to the chronology of the Palaeogene lava fields of the British Province: implications for magmatic stratigraphy [PDF]

open access: yes, 1997
New high-precision ages, determined from palynomorph assemblages within intercalated sedimentary deposits, are presented for the Palaeogene lava fields (Skye, Mull and Antrim) of the British Province. These data reveal very rapid averaged eruption rates (

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 ...

Depositional Sedimentary Facies, Stratigraphic Control, Paleoecological Constraints, and Paleogeographic Reconstruction of Late Permian Chhidru Formation (Western Salt Range, Pakistan)

open access: yesJournal of Marine Science and Engineering, 2021
The Upper Indus Basin, in Pakistan’s western Salt Range, is home to the Zaluch Gorge. The sedimentary rocks found in this Gorge, belonging to the Chhidru Formation, were studied in terms of sedimentology and stratigraphy, and provide new insights into ...

The East Gotland Basin (Baltic Sea) as a candidate Global boundary Stratotype Section and Point for the Anthropocene series

open access: yesThe Anthropocene Review, 2022
The short sediment core EMB201/7-4 retrieved from the East Gotland Basin, central Baltic Sea, is explored here as a candidate to host the stratigraphical basis for the Anthropocene series and its equivalent Anthropocene epoch, still to be formalized in ...

The Vuelo Ruiz de Alda (1929-30): an exceptional cartographic document. Again about Ilici

open access: yesSagvntum, 2015
In this paper we introduce a first evaluation of the potential of a magnificent resource, as is the photographic series known as Vuelo Ruiz de Alda (1929-30), for the archaeological investigation and in particular the stratigraphy of the landscape.

Seismic stratigraphy of the Ontong Java Plateau [PDF]

open access: yes, 1993
The Ontong Java Plateau, a large, deep-water carbonate plateau in the western equatorial Pacific, is an ideal location for studying responses of carbonate sedimentation to the effects of changing paleoceanographic conditions.
