Estimation of bedload sedimentation rate in a paleo-drowned river-valleyJournal 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

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
Paleocurrent analysis, petrographic, geochemical and statistical appraisal of Neoproterozoic siliciclastic sediments, NE Voltaian Basin, Ghana: a multidisciplinary approach to paleogeographic reconstructionJournal 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
Estimation of siltation in Tuirial dam: a spatio-temporal analysis using GIS technique and bathymetry surveyJournal 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
