Experimental evidence of sulfide melt evolution via immiscibility and fractional crystallization

Mavrogenes, John; Frost, B Ronald; Sparks, Heather

Description

Most ore deposits in high-grade metamorphic terranes show signs of remobilization of sulfide ores. During this process the compositions and tenor of the ore change dramatically. In this report we show the results of a study designed to clarify chemical modification of sulfide melts as they cool from high temperatures. Sulfide melts were allowed to "trickle down" through a permeable inert host over an extreme temperature gradient. The effects of crystal fractionation and liquid immiscibility can...[Show more]
