Abstract
Characterization of the genetic relations between magma suites and associated gold/base metal hydrothermal deposits is imperative to our understanding of the role of magmas in the mineralization process. Melt inclusions trapped in igneous phenocrysts were used to characterize calc–alkaline magmas associated with Valea Morii porphyry–copper deposit, Romania. A comparative study of mineralized intrusion versus barren intrusion reveals parameters that may influence the magmatic–hydrothermal connection. The present results emphasize the importance of the chemistry of residual melts (trapped in magmatic inclusions) rather than bulk magma compositions (derived from whole rock analysis) in determining the metal concentration in released magmatic fluid.
