The physical and chemical properties of aqueous fluids and melts, and how these evolve through time and space, are key controlling factors that govern the formation of mineral deposits. For some metal-rich system types such as iron oxide-apatite deposits (IOA), the sources and chemical...

The evolution of calcite-bearing kimberlites by melt-rock reaction: evidence from polymineralic inclusions within clinopyroxene and garnet megacrysts from Lac de Gras kimberlites, Canada

Luth, R. W., Stone, Rebecca, Menzies, Andrew, Bussweiler, Yannick, Pearson, Graham, Stachel, Thomas, Kjarsgaard, B. A.
Megacrystic (>1 cm) clinopyroxene (Cr-diopside) and garnet (Cr-pyrope) xenocrysts within kimberlites from Lac de Gras (Northwest Territories, Canada) contain fully crystallized melt inclusions. These ‘polymineralic inclusions’ have previously been interpreted to form by necking down of melts at...
