Study on Geochemical Characteristics of Rare Earth Elements of Xinhua Phosphate Rocks in the Upper Yangtze, South China by ICP-MS/AES and Its Sedimentology Implications

open access: yesYankuang ceshi, 2015
Xinhua phosphorus is a sedimentary phosphate deposit in China with strong REEs enrichment. In this study, Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES) as well as rock-mineral ...

From Site Selection to Characterization: Assessment of Potential Reservoirs in the Lurestan Basin of Iran for Carbon Sequestration

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The increasing global focus on carbon sequestration underscores the need for comprehensive CO2 storage atlases, extending beyond Europe and America to other countries that are significant contributors to carbon dioxide emissions. This article addresses this imperative by examining the CO2 storage potential in the Lurestan area of Iran, with a ...

The SPICE carbon isotope excursion in Siberia: a combined study of the upper Middle Cambrian-lowermost Ordovician Kulyumbe River section, northwestern Siberian Platform [PDF]

open access: yes, 2008
An integrated, high-resolution chemostratigraphic (C, O and Sr isotopes) and magnetostratigraphic study through the upper Middle Cambrian–lowermost Ordovician shallowmarine carbonates of the northwestern margin of the Siberian Platform is reported. The

Geological Screening for CO2 Storage in Deep Saline Aquifers in the Lower Mainland British Columbia (LMBC), Canada

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Deep saline aquifers and depleted reservoirs are prime candidates for CO2 storage, but feasibility assessments remain limited in regions with little oil and gas activity, such as the Lower Mainland of British Columbia (LMBC), Canada. This study evaluates the CO2 storage potential of the Georgia Basin strata beneath the LMBC, focusing on three ...

On building and fitting a spatio-temporal change-point model for settlement and growth at Bourewa, Fiji Islands [PDF]

open access: yesarXiv, 2010
The Bourewa beach site on the Rove Peninsula of Viti Levu is the earliest known human settlement in the Fiji Islands. How did the settlement at Bourewa develop in space and time? We have radiocarbon dates on sixty specimens, found in association with evidence for human presence, taken from pits across the site.

Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

open access: yesGeological Journal, EarlyView.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

South Atlantic continental margins of Africa: a comparison of the tectonic vs climate interplay on the evolution of equatorial west Africa and SW Africa margins

open access: yes, 2005
The comparative review of 2 representative segments of Africa continental margin: the equatorial western Africa and the SW Africa margins, helps in analysing the main controlling factors on their development.

Reconstruction of eolian bed forms and paleocurrents from cross-bedded strata at Victoria Crater, Meridiani Planum, Mars [PDF]

open access: yes, 2011
Outcrop exposures imaged by the Opportunity rover at Victoria Crater, a 750 m diameter crater in Meridiani Planum, are used to delineate sedimentary structures and further develop a dune-interdune depositional model for the region.
