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

, 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.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

A Survey of Climatic Changes of Namak Lake Basin in the Late Quaternary [PDF]

نشریه جغرافیا و برنامه‌ریزی, 2014
Two important characteristics, alternate climatic fluctuations and human being appearance, distinguish Quaternary from other geology periods. These climatic changes have shown increase and decrease of glacialical scope in high latitudes, but there are ...

Holistic 3D Model of an Urban Area in Norway: An Integration of Geophysical, Geotechnical, Remote Sensing, and Geological Methods

Remote Sensing, 2023
Understanding the distribution and characterization of natural and non-natural materials on the surface and near-subsurface is important for the development of infrastructure projects. This may be a challenge in highly urbanized areas, where outcrops are

Geomorphology of the Kaikoura area [PDF]

, 1968
The major physiographic units in the Kaikoura area are the Peninsula Block, Beach Ridges and Raised Beaches, Hard Rock Areas and the Alluvial Fans. Erosion of the Seaward Kaikoura Mountains and the transfer of the debris to the sea by fan streams have ...

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

Subglacial geology and palaeo flow of Pine Island Glacier from combining glacial erratics with geophysics

Communications Earth & Environment
Subglacial geology plays a key role in determining the rate of ice flow and sensitivity of the glacial system to atmospheric or ocean warming. However, bedrock geology is often poorly known because direct information from subglacial samples is extremely ...

The surficial geology record of ice stream catchment dynamics and ice-divide migration in the Quebec-Labrador sector of the Laurentide Ice Sheet

Quaternary Science Advances
The surficial geology of an approximately 30 000 km2 region in northeastern Quebec and western Labrador was mapped to elucidate the glacial dynamics of a region that experienced ice divide migrations and determine the net effect of this evolution on the ...

Hydrogeologic and Thermal Effects of Glaciations on the Intracontinental Basins in Central and Northern Europe

Frontiers in Water, 2022
We use a fully coupled hydro-thermal model (TH) to quantify changes in the pore pressure and temperature distribution following the Last Glacial Maximum (LGM) in the intracontinental basins in Central and Northern Europe. We demonstrate that even without

“Hidden” Landscape of Prehistoric Burial Monuments: The Use of Remote Sensing in the Detection of Neolithic Long Barrows in Bohemia (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long‐term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated ...
