Louis Jean-Pierre Cabri (born February 23, 1934, in Cairo) is an eminent [1] Canadian scientist in the field of platinum group elements (PGE) mineralogy with expertise in precious metal mineralogy and base metals at the Canada Centre for Mineral and Energy Technology (CANMET).
His son Louis Andrew De Meillon Cabri is a Canadian writer and poet (New Creative Writing).
According to The Royal Society of Canada, Louis J. Cabri "...attained international eminence for his work on sulphides and tellurides, on the platinum-groupminerals, and ... for pioneering mineralogical applications of micro-beam trace-element analytical techniques such as micro-Proton-induced X-ray emission (PIXE) and Secondary-Ion Mass Spectrometry (SIMS).
All his work is characterized by innovative experimental approaches that have greatly advanced our knowledge and understanding of the behaviour of precious metals in Earth systems and mineral process products.
Later, he pursued phase-stability and crystal-chemistry relationships in the [Cu–Fe–S] (Copper-Iron-Sulfide) System, which led to his discovery in 1972 of two new Cu–Fe sulfide minerals, "Mooihoekite" ( Cu9Fe9S16) and "Haycockite" (Cu4Fe5S8).
