Estimation of bedload sedimentation rate in a paleo-drowned river-valley
Journal of Sedimentary Environments - Tập 7 Số 4 - Trang 633-650 - 2022
S.P. Lound, G.F. Birch, Deirdre Dragovich
AbstractExtensive, high-resolution seismic data were correlated with borehole, land use, and geological data to calculate the mass of genetically different sediment deposits in the Middle Harbour estuary in Sydney, Australia. Middle Harbour is a drowned-river valley located adjacent to the larger Sydney estuary. The estuary follows a well-defined sedimentation mode...... hiện toàn bộ

Lake level oscillations recorded in Buracica Stage (Barremian, Early Cretaceous) of Recôncavo Basin, Bahia State (N.E. Brazil)
Journal of Sedimentary Environments - Tập 5 - Trang 425-456 - 2020
Jorge C. Della Fávera, Hemani A. Fernandes Chaves, Marco André Malmann Medeiros, Cícera Pereira de Meneses, Maria Edilmeire A. Tavares, Maria Eugenia González, Maria Luciete D. Pinheiro, Orlando Cristiano da Silva, Maria Virginia Alves Martins
This work studies the Buracica Stage (Barremian, Early Cretaceous) in the Recôncavo Basin, Bahia State (N.E. Brazil), comprising the São Sebastião and Pojuca formations, from the analysis of 143 well logs and outcrop records. The Recôncavo Basin is a rift basin associated with the beginning of the South Atlantic Ocean. The basin started with very slow subsidence rates, leading to the formation of ...... hiện toàn bộ
Characterizing spatial variability of some soil properties in Beni-Moussa irrigated perimeter from Tadla plain (Morocco) using geostatistics and kriging techniques
Journal of Sedimentary Environments - Tập 6 - Trang 381-394 - 2021
El Hassania El Hamzaoui, Mohamed El Baghdadi
The research was carried out in Beni-Mousssa perimeter in the southern part of the Tadla plain, in Morocco. This study was performed using physicochemical analyses combined with statistical and geostatistical analysis to understand the spatial variability of soil quality in this agricultural area and to elaborate sustainable management of soil and environmental decision. The locations of sampling ...... hiện toàn bộ
Geochemical and multivariate statistical characterization of shales of the Oti−Pendjari Group of the Neoproterozoic Basin of Ghana: implication of paleoweathering, climatic conditions, and provenance
Journal of Sedimentary Environments - Tập 8 - Trang 115-135 - 2023
Mahamuda Abu, Samuel Nunoo, Raymond Webrah Kazapoe
The Oti−Pendjari Group of the Voltaian basin is the largest and thickest of the three Groups of the basin and has had limited  research attention over the years. In this study, the geochemical characterization of the group with a focus on elucidating the paleoclimatic conditions, weathering, and the provenance of the argillaceous detritus was investigated. On the basis of Sr/Cu ratios and C values...... hiện toàn bộ
Chemical composition of garnet and ilmenite from stream sediments and soil applied to diamond fertility investigation: the kimberlite intrusion of Ariquemes, Rondonia (Brazil)
Journal of Sedimentary Environments - Tập 7 - Trang 317-334 - 2022
Karine Mahon, Maria Virginia Alves Martins, Mauro Cesar Geraldes
In exploratory programs for kimberlites focused at discovering diamond deposits, it is important to identify tools that define their fertility. The observation of mineral indices such as garnet and ilmenite is the first indication of the proximity of kimberlite intrusion, and the possibility of using these minerals as fertility proxys through mineral chemistry allows us to characterize the presenc...... hiện toàn bộ
Paleocurrent analysis, petrographic, geochemical and statistical appraisal of Neoproterozoic siliciclastic sediments, NE Voltaian Basin, Ghana: a multidisciplinary approach to paleogeographic reconstruction
Journal of Sedimentary Environments - Tập 5 - Trang 199-218 - 2020
Mahamuda Abu, Emmanuel Daanoba Sunkari, Ali Gürel
This study used sedimentary structures, facies analysis, petrographic studies, statistical techniques and geochemical data of the Bombouaka/Gambaga Group of the NE Voltaian Basin, Ghana to decipher the source of the sediments. Field measurements covered the Tossiegou, Poubogou, and Panabako Formations of the Bombouaka/Gambaga Group. The influence of hydraulic sorting was interpreted from the effec...... hiện toàn bộ
Influence of low-temperature fluids and post-depositional changes in the siliceous–pelagic sediments of the Central Indian Ocean Basin

Estimation of siltation in Tuirial dam: a spatio-temporal analysis using GIS technique and bathymetry survey
Journal of Sedimentary Environments - - Trang 1-17 - 2023
Imanuel Lawmchullova, Ch. Udaya Bhaskara Rao
Dams are the source of power generation which also provide water supply for irrigation and other domestic needs. Siltation is the major issue, particularly in shortening the life span of the dams worldwide. Mizoram is highly fragile due to its undulating topography and loose sedimentary rock formations. Accumulated sediment is estimated to be high due to high run-off over steep slopes. This area l...... hiện toàn bộ
