Abstract The origin of magnetite-(apatite) iron deposits (MtAp) is one of the most contentious issues in ore geology with competing models that range from hydrothermal to magmatic processes. Here we report melt inclusions trapped in plagioclase pheno

The long-standing controversy about the origin of magnetite-(apatite) mineral deposits pertains to how they form. The Pleistocene El Laco deposit in northern Chile is a critical location because the host andesite contains immiscible melt inclusions t

Magnetite-apatite deposits are important sources of iron and other metals. A prominent exam- ple are the magnetite lavas at the El Laco volcano, Northern Chile. Their formation processes remain debated. Here, we test the genetic hypothesis that an Fe
