The compounds, lanthanium chromite, lanthanium magnetite and lanthanium ferric oxide were prepared through sol-gel methods in powdered form, then calcinated, peletized, and sintered at various temperatures. Electrical conductivity of these compounds was measured at various temperatures. The effectiveness of strontium as a dopant on electrical conductivity was also investigated. Electrical condu...
Mg-Fe2+ diffusion patterns in olivine and chromite are useful tools for the study of thermal history ultramafic massifs. In present contribution, we applied exponential modeling to geothermometry geospeedometry chromitite ores from two different ophiolite contexts. The Iballe (Northern Albania) hosts several pods within dunites. Primary re-equilibrated Mg#, estimated by using an function, provi...
