Lithogeochemical and mineralogical indicators of Andean precious-metal and polymetallic vein mineralization
(ElsevierNL, 1989-04)
Proximal and distal lithogeochemical alteration patterns associated with precious-metal and polyTnetallic vein mineralization in the Andes of Bolivia and Peru are delineated both by sulphophile elements such as Ag, As, Pb, ...

Determination of precious and rare metals in minerals concentrates and tailings, using k_0 based instrumental neutron activation analysis
(LimaPE, 2002-06)
Under the frame of CRP “Validation of nuclear techniques for analysis of precious and rare metals in mineral concentrates”, in order to improve the utilization of nuclear analytical techniques in terms of high accuracy and ...
A secondary precious and base metal mineralization in chromitites linked to the development of a Paleozoic accretionary complex in Central Chile
(2016)
Platinum-group element (PGE) and gold inclusions are usually present in peridotites and chromitite deposits associated with ophiolites. Here, we present the first detailed study of the mineralogy of precious metals in ...

Predictores de reactividad de of non-precious MNx catalysts for O2 reduction in terms of redox potentials, and molecular hardness
(2016)
We and other authors have demonstrated [1,2] that the electrocatalytic activity of macrocyclic transition metal complexes for ORR is directly connected to the Eo’, the M(n)/(n-1) formal potential of the catalyst and this ...

Geochemistry of metals and metalloids in siliceous sinter deposits: Implications for elemental partitioning into silica phases
(Elsevier, 2017)
Sinter deposits are formed by precipitation of silica from hydrothermal fluids that have reached the
surface environment. They are commonly found around hot springs and represent surface expressions of
underlying geothermal ...
