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 (

Seasonal lake‐to‐air temperature transfer functions derived from an analysis of 1395 modern lakes: A tool for reconstructing air temperature from proxy‐derived lake water temperature

open access: yesThe Depositional Record, EarlyView.
This study introduces new transfer functions, developed using statistical modelling of air temperature reanalysis data and satellite observations for 1395 modern lakes, to translate proxy‐derived lake water temperatures into air temperatures for more accurate reconstructions.

A deep convolutional encoder-decoder neural network in assisting seismic horizon tracking [PDF]

open access: yesarXiv, 2018
Seismic horizons are geologically significant surfaces that can be used for building geology structure and stratigraphy models. However, horizon tracking in 3D seismic data is a time-consuming and challenging problem. Relief human from the tedious seismic interpretation is one of the hot research topics.

The stratigraphy, correlation, provenance and palaeogeography of the Skiddaw Group (Ordovician) in the English Lake District [PDF]

open access: yes, 1995
A new lithostratigraphy is presented for the Skiddaw Group (lower Ordovician) of the English Lake District. Two stratigraphical belts are described. Five formations are defined in the Northern Fells Belt, ranging in age from Tremadoc to early Llanvirn.

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Remote Stratigraphic Analysis: Combined TM and AIS Results in the Wind River/bighorn Basin Area, Wyoming [PDF]

open access: yes, 1985
An in-progress study demonstrates the utility of airborne imaging spectrometer (AIS) data for unraveling the stratigraphic evolution of a North American, western interior foreland basin.

Response and Recovery of the Comanche Carbonate Platform Surrounding Multiple Cretaceous Oceanic Anoxic Events, Northern Gulf of Mexico [PDF]

open access: yes, 2015
The ubiquity of carbonate platforms throughout the Cretaceous Period is recognized as a product of high eustatic sea-level and a distinct climatic optimum induced by rapid sea-floor spreading and elevated levels of atmospheric carbon-dioxide.

South American Great Basin: Limnogeological analysis of the Salina del Bebedero Basin, Argentina (Late Pleistocene‐recent)

open access: yesThe Depositional Record, EarlyView.
. The Bebedero tectonic depression in San Luis province, Argentina, is a closed drainage basin that has formed as a result of block‐faulting and rifting processes. The Bebedero lake exhibits notable similarities to the endorheic watersheds of the western United States, particularly those of Death Valley, the Saline Valley and, to a lesser extent, the ...
