As society transitions to low-carbon, renewable energy resources, the demand for metals
and minerals is set to increase. Massive quantities of base metals and mineral materials (for …

Degradation and pollution of land resources is a severe issue worldwide. Rapid
urbanization and increased food demand have necessitated the restoration of degraded and …

In tropical iron ore regions, biologically mediated reduction of crystalline iron oxides drives
ongoing iron cycling that contributes to the stability of surface duricrusts. This represents a …

Iron-rich duricrusts (canga) that blanket iron ore deposits in tropical regions in Brazil have a
complex formation and evolution. The direct role of microorganisms in the biogeochemical …

Mined sub-aerially stored kimberlite provided a natural laboratory in which to examine the
potential for carbon sequestration in ultramafic materials. A 15 cm hand sample of∼ 50-year …

Microbial biofilms growing in iron-rich seeps surrounding Lake Violão, Carajás, Brazil serve
as a superb natural system to study the role of iron cycling in producing secondary iron …

Iron formations display some of the oldest and most enigmatic landforms on Earth, presently
restricted to few areas of the planet. The original rock, the Banded Iron Formation (BIF) was …

The Carajás plateaus in Brazil host endemic epilithic vegetation (“campo rupestre”) on top of
ironstone duricrusts, known as canga. This capping rock is primarily composed of iron (III) …

Microbiological weathering of coarse residue deposit (CRD) kimberlite produced by the
Venetia Diamond Mine, Limpopo, South Africa enhanced mineral carbonation relative to …

Hydrocarbon pollution is a widespread issue in both groundwater and surface-water
systems; however, research on remediation at the interface of these two systems is limited …
