This study investigated the environmental quality of Bizerte Lagoon (Tunisia) through an integrated approach that combined environmental, biogeochemical, and living benthic foraminiferal analyses. Specifically, we analyzed physicochemical parameters water sediment. The textural, mineralogical, geochemical characteristics sediment, including total organic carbon, nitrogen, simultaneously extracted metals (SEM), acid volatile sulfides (AVS), chlorophyll a, CaCO3, changes in bacterial...

Abstract Gondwana was an enormous supertarrane. At its peak, it represented a landmass of about 100 × 10 6 km 2 in size, corresponding to approximately 64% all land areas today. assembled the Middle Cambrian, merged with Laurussia form Pangea Carboniferous, and finally disintegrated separation East West at 170 Ma, Africa South America around 130 Ma. Here we have updated plate reconstructions from history, special emphasis on interactions between continental crust mantle plumes resulting...

The end-Triassic is characterized by one of the largest mass extinctions in Phanerozoic, coinciding with major carbon cycle perturbations and global warming. It has been suggested that environmental crisis linked to widespread sill intrusions during magmatism associated Central Atlantic Magmatic Province (CAMP). Sub-volcanic sills are abundant two onshore sedimentary basins Brazil, Amazonas Solimões basins, where they comprise up 20% stratigraphy. These contain extensive deposits carbonate...

Identification of underground formation lithology from well-log data is an important task in petroleum exploration and engineering. Due to the cost or imprecision some methods applied this activity, there a need automate procedure reservoir characterization. Machine learning techniques can be efficient alternatives identification. To acquire proper performance, usually, parameters these should adjusted, become hard depending on complexity underlying problem. This letter integrates gradient...

Rock samples' TOC content is the best indicator of organic matter in source rocks. The origin rock analysis used to calculate it manually by specialists. This method requires time and resources because relies on samples from many well intervals Therefore, research has been done aid this effort. Machine learning algorithms can estimate total carbon instead logs stratigraphic studies. In light these efforts, current work present a study automating estimation using machine approaches improved...

Abstract The taxonomy and distribution of Chitinozoa from Silurian (Llandovery) Lower Devonian strata are reported the Parana Basin in southern Brazil eastern Paraguay. pre‐Carboniferous sequences this area present three sub‐basins viz., Alto Garcas (north) Apucarana (south) Brazil, “East Paraguay Sub‐basin”; east There is more similarity lithology between Paraguay”; sub‐basins, than former sub‐basin. Llandoverian Lochkovian to Pragian beds all sub‐basins. So far, no Emsian have been found...
