Implication of geological domains data for modeling and estimating resources from Nkout iron deposit (South-Cameroun) [PDF]
Journal of Mining and Metallurgy. Section A: Mining, 2021 This paper is devoted to determining whether the addition of geological information can improve the resource estimate of mineral resources. The geochemical data used come from 116 drill holes in the Nkout East iron deposit in southern Cameroon.

A Coupled Geochemical‐Geodynamic Approach for Predicting Mantle Melting in Space and Time
Geochemistry, Geophysics, Geosystems, 2022 Geodynamic simulations underpin our understanding of upper‐mantle processes, but their predictions require validation against observational data. Widely used geophysical datasets provide limited constraints on dynamic processes into the geological past ...

Geochemical modeling of mercury in coastal groundwater
Chemosphere, 2022 The systematic analysis of groundwater in the Greek island of Skiathos revealed a seasonal increase of total mercury concentrations after the extensive groundwater abstraction during the busy and heavily touristic summer months. This contamination was accompanied by a corresponding increase of the chloride content of groundwater, attributed to seawater

pH as a Primary Control in Environmental Microbiology: 1. Thermodynamic Perspective
Frontiers in Environmental Science, 2018 pH influences the occurrence and distribution of microorganisms. Microbes typically live over a range of 3–4 pH units and are described as acidophiles, neutrophiles, and alkaliphiles, depending on the optimal pH for growth.
