A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Mineral Composition and Full-Scale Pore Structure of Qianjiadian Sandstone-Type Uranium Deposits: Application for In Situ Leaching Mining

Geofluids, 2022
In situ leaching (ISL) is becoming the main mining practice for sandstone-type uranium deposits in China. The key to ISL technology is to aid the leaching solution in contacting the ore bed over a large range, which will induce a series of chemical ...

When Density Matters: Hydraulic and Salinity Evolution in Groundwater‐Fed Pit Lakes in Semiarid and Arid Climates

Groundwater, EarlyView.
Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Geochemical and S isotopic studies of pollutant evolution in groundwater after acid in situ leaching in a uranium mine area in Xinjiang

Nuclear Engineering and Technology, 2023
Laboratory experiments and point monitoring of reservoir sediments have proven that stable sulfate reduction (SSR) can lower the concentrations of toxic metals and sulfate in acidic groundwater for a long time.

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis

Review of Development Economics, EarlyView.
ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.
