Hydrologically sensitive carbonates: Tectonic and groundwater controls on synrift sedimentation in the Late Jurassic–Early Cretaceous of the western Cameros Basin, Northern Spain

The Depositional Record, EarlyView.
Late Jurassic extension, footwall uplift, erosion and karstification of marine Jurassic carbonates in the western Cameros Basin (Spain) resulted in the deposition of ?Upper Kimmeridgian‐Tithonian syntectonic alluvial fan deposits and a series of ?Tithonian to Berriasian distal alluvial marls, palustrine, lacustrine and finally lagoonal carbonates.

Drainage network development in the Pannonian Basin

Hungarian Geographical Bulletin, 2015
The evolution and development of the greatest rivers in the Pannonian Basin have been investigated for almost 150 years. At the end of the Late Miocene Sub-Epoch (7.5-5.3 Ma BP) and at the beginning of Pliocene Epoch (5.3-4.5 Ma BP) Lake Pannon shrank ...

Ages on weathered Plio-Pleistocene tephra sequences, western North Island, New Zealand [PDF]

, 2001
Using the zircon fission-track method, we have obtained five ages on members of two strongly-weathered silicic, Pliocene-Pleistocene tephra sequences, the Kauroa and Hamilton Ash formations, in western North Island, New Zealand.

The influence of syn‐depositional compaction on clastic sediment distribution in river‐dominated deltas: A modelling study

The Depositional Record, EarlyView.
The impact of syn‐depositional compaction on the sedimentation distribution and the interdependency between different delta areas related to the sediment budget are not fully understood. Our result shows that compaction creates additional accommodation space that leads to more sedimentation in the delta plain, while limiting sediment delivery towards ...

The absolute chronology of the Late Bronze Age settlements Kammenyi Ambar and Ust’ye I in the Southern Trans-Urals and its Bayesian analysis

Вестник археологии, антропологии и этнографии, 2020
In this paper, we examine the series of AMS radiocarbon measurements (N = 52) obtained from the Late Bronze Age settlements of Kamennyi Ambar and Usty’e I in the Southern Trans-Urals, Russia.

Coming to light: How effective are sediment gravity flows in removing fine suspended carbonate from reefs?

The Depositional Record, EarlyView.
This paper presents laboratory experiments that investigated the dynamics of mud‐grade calcite laden gravity flows, with the aim of determining how mobile these calciclastic flows are in comparison to fine‐grained cohesive and non‐cohesive siliciclastic gravity flows.

Composition and origin of the Middle Weichselian interstadial deposit in Veskoniemi, northern Finland [PDF]

Estonian Journal of Earth Sciences, 2010
The stratigraphy and sedimentology of a diamicton-stratified sand deposit have been studied in the Veskoniemi area, near Lake Inarijärvi in central Finnish Lapland. Test pit excavations were used for stratigraphical investigations.

Dynamic and Isotopic Evolution of Ice Reservoirs on Mars [PDF]

, 2019
The layered polar caps of Mars have long been thought to be related to variations in orbit and axial tilt. We dynamically link Mars's past climate variations with the stratigraphy and isotopic composition of its ice by modeling the exchange of H2O and HDO among three reservoirs.

Anatomy of modern sedimentary volcanoes produced by gas‐charged groundwater liquefaction, Lake Powell, Hite, Utah: Implications for the recognition and interpretation of ancient sedimentary volcanoes

The Depositional Record, EarlyView.
Two non‐seismically generated sedimentary volcanoes were excavated on the Colorado River delta in Lake Powell, Utah, USA, in order to characterise the internal structures. Sedimentary volcanoes are commonly employed as tools in palaeoseismic reconstruction, thus it is important to establish criteria to differentiate non‐seismic‐generated sedimentary ...

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

Yankuang 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 ...
