Sedimentary manganese (Mn) mineralization requires a switch between anoxic and oxic water column conditions, which is commonly explained by the “bathtub ring” model and more recently interpreted by the emerging “episodic ventilation” model. To date, however, it remains unclear regarding how to di...
The objective of this study is to investigate the impact of MnOxaddition on the efficiency of Fe0/H2O systems for MB discoloration as a function of the experimental duration (contact time). The specific objective is to confirm the suitability of ‘MB discoloration’ as powerful tool for the ch...
The generation of magnetic anomalies by combustion metamorphism of sedimentary rock, and its significance to hydrocarbon exploration Low-temperature exothermic oxidation of fine pyrite in carbonaceous marine rocks can lead to spontaneous combustion. As a result, the organic material in t... S.,M.,CIS...
Bedding parallel fracture Fine-grained sedimentary rocks Image logs Lucaogou Formation 1. Introduction Fine-grained sedimentary rocks, which are deposited in low-energy environments, account for 2/3 of the entire sedimentary sequences, and they are both source rocks and effective reservoirs for unconve...

Redox sensitive trace elements in pyrite, including nodules, are increasingly used to infer the chemical conditions of ancient oceans but considerable uncertainty remains regarding the mechanism and timing of nodule formation. Resolving these uncertainties is important because pyrite nodules must form in ...
2The geography of the study area 2.1Location, size, and climate Sokoto basin, otherwise known as the Iullemmeden basin (Fig.1), is part of an extensive elongated sedimentary basin in west Africa. It covered most of Northwestern Nigeria and eastern parts of the Niger Republic. The basin is...
Marine conditions prevailed in the area of interest during Jurassic and large parts of Cretaceous times, and sedimentation took place. It is therefore safe to say that pore-waters in the sedimentary pile had a composition close to that of sea-water. In the late Cretaceous, the basin was inver...
