Towards a sequence stratigraphic solution set for autogenic processes and allogenic controls: Upper Cretaceous strata, Book Cliffs, Utah, USA [PDF]

open access: yes, 2016
Upper Cretaceous strata exposed in the Book Cliffs of east–central Utah are widely used as an archetype for the sequence stratigraphy of marginal-marine and shallow-marine deposits.

Nitrogen isotopes in bulk marine sediment: linking seafloor observations with subseafloor records [PDF]

open access: yesBiogeosciences, 2013
The stable isotopes of nitrogen offer a unique perspective on changes in the nitrogen cycle, past and present. However, the presence of multiple forms of nitrogen in marine sediments can complicate the interpretation of bulk nitrogen isotope measurements.

Sedimentation record in the Konkan-Kerala Basin: implications for the evolution of the Western Ghats and the Western Indian passive margin [PDF]

open access: yes, 2007
The Konkan and Kerala Basins constitute a major depocentre for sediment from the onshore hinterland of Western India and as such provide a valuable record of the timing and magnitude of Cenozoic denudation along the continental margin.

Influence of palaeoweathering on trace metal concentrations and environmental proxies in black shales [PDF]

open access: yes, 2017
The mineralogical and chemical compositions of Lower Carboniferous (Tournaisian) marine black shale from the Kowala quarry, the Holy Cross Mountains, Poland, were investigated.

Kom W and X Basin: Erosion, Deposition, and the Potential for Village Occupation [PDF]

open access: yes, 2020
The twentieth-century excavations of stratified deposits at Kom W, adjacent to Lake Qarun in Fayum north shore, Egypt, led to a variety of interpretations, including the argument for the presence of a Neolithic village. This has influenced the evaluation

The El Masnou Infralittoral sedimentary environment (Barcelona province, NW Mediterranean Sea): morphology and Holocene seismic stratigraphy [PDF]

open access: yes, 2010
A detailed analysis of the morphology and the Holocene seismic and sequence stratigraphy and architecture of the infralittoral sedimentary environment of the El Masnou coast (Catalonia, NW Mediterranean Sea) was carried out using multibeam bathymetry and

Coupled ‘storm-flood’ depositional model: application to the Miocene–Modern Baram Delta Province, north-west Borneo [PDF]

open access: yes, 2016
The Miocene to Modern Baram Delta Province is a highly efficient source to sink system that has accumulated 9 to 12 km of coastal-deltaic to shelf sediments over the past 15 Myr.

Mercury deposition and redox transformation processes in peatland constrained by mercury stable isotopes

open access: yesNature Communications, 2023
Peatland vegetation takes up mercury (Hg) from the atmosphere, typically contributing to net production and export of neurotoxic methyl-Hg to downstream ecosystems. Chemical reduction processes can slow down methyl-Hg production by releasing Hg from peat

Al–Cu intermetallic coatings processed by sequential metalorganic chemical vapour deposition and post-deposition annealing [PDF]

open access: yesApplied Surface Science, 2012
Abstract Sequential processing of aluminum and copper followed by reactive diffusion annealing is used as a paradigm for the metalorganic chemical vapour deposition (MOCVD) of coatings containing intermetallic alloys. Dimethylethylamine alane and copper N,N′-di-isopropylacetamidinate are used as aluminum and copper precursors, respectively ...
