The behaviour of platinum-group elements during magmatic differentiation in Hawaiian tholeiites.

A Review of the Behaviour of Platinum Group Elements within Natural Magmatic Sulfide Ore Systems

School of Earth and Ocean Sciences, Cardiff University, Main Building, Park Place, Cardiff CF10 3YE, UK The largest and most significant type of geological deposit of platinum group elements (PGEs) is that associated with magmatic base metal sulfide minerals in layered mafic or ultramafic igneous intrusions.The common association of PGEs with sulfide minerals is a result of processes of magmati...

Chromite – Platinum-Group Element Magmatic Deposits

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Accumulation of Platinum Group Elements

Accumulation of Platinum Group Elements by the Marine Microalga, Chlorella stigmatophora Leyla Shams Very little information exists on the marine biogeochemistry of Rh, Pd and Pt, or the platinum group elements (PGE), an emerging group of contaminants whose priiicipal emissions are associated with the abrasion of the catalytic converter in motor vehicles and chemotherapy drugs discharged in hos...
