Molybdenum is an essential trace element for human, animal and plant health and has
played an important part in the evolution of life on earth. Nonetheless, exposure to the …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Paleoredox conditions are commonly evaluated based on elemental proxies but, despite
their frequency of use, most of these proxies have received little comparative evaluation or …

Many workers accept a metamorphic model for orogenic gold ore formation, where a gold-
bearing aqueous-carbonic fluid is an inherent product of devolatilization across the …

The chemical composition, textures and mineral associations of pyrite provide key
information that help elucidate the evolution of hydrothermal systems. However, linking the …

Faced with ongoing depletion of near-surface ore deposits, geologists are increasingly
required to explore for deep deposits or those lying beneath surface cover. The result is …

A large proportion of the critical elements resources Ge, Ga, and In are associated with
sphalerite in Pb-Zn ore deposits. Germanium in sphalerite has been proposed to be …

Laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) has rapidly
established itself as the method of choice for generation of multi-element datasets for …

Laser ablation-inductively coupled plasma-mass spectrometry and electron-probe
microanalysis were used to investigate the trace-element contents of sphalerite, chalcopyrite …

Porphyry deposits host various trace elements in economic amounts, but the hydrothermal
processes causing their fractionation and enrichment are still not fully understood, but vital to …
