Sedimentary facies and depositional environments of diverse early paleocene floras, north-central San Jorge basin, Patagonia, Argentina [PDF]

, 2015
We here investigate the sedimentology of the early Danian (ca. 66-64 Ma) Salamanca Fm. in the north-central San Jorge Basin, southern Chubut Province, Patagonia, Argentina, in order to place the outstandingly diverse and well-preserved fossil floras it ...

Luminescence dating of coastal deposits from the Chanthaburi Plain, Thailand

Boreas, EarlyView.
The ongoing global sea‐level rise urges us to better understand the dynamics of coastal processes for predicting future changes. Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context.

Sedimentary evolution and petroleum geological significance of Permian Maokou Formation in eastern and northern Sichuan Basin

Shiyou shiyan dizhi
In recent years, the Permian Maokou Formation of the Sichuan Basin shifted focus. Previously, targeting high points and exploring along the long axis were common.

Reservoir Prediction Under Control of Sedimentary Facies

, 2017
Acoustic impedance (AI) from seismic inversion can indicate rock properties and can be used, when combined with rock physics, to predict reservoir parameters, such as porosity.

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

Boreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

Lithofacies paleogeography of the Ordovician Kelimoli-Lashizhong formations along the western margin of the Ordos Basin

Meitian dizhi yu kantan
ObjectiveThe period during the deposition of the Middle-Late Ordovician Kelimoli-Lashizhong formations witnessed a key transition of the tectonic framework along the western margin of the Ordos Basin. Investigating the lithofacies paleogeography of these

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Analysis of sedimentary facies and depositional environment of the Yuanjiacun banded iron formation in the Luliang area, Shanxi Province

, 2015
The Yuanjiacun banded iron formation (BIF), located in the Luliang area, is likely to be the most representative Superior-type BIF in the North China Craton (NCC).
