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

Can volcanoes erupt ore deposits? This study combines observations, experiments, and simulations to show that iron ore deposits on El Laco volcano formed by eruption of melt sourced from separation of Fe-rich melt from a silicate magma body beneath.

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

The origin of magnetite-(apatite) iron deposits (MtAp) is among the most contentious issue in ore geology with competing models involving purely hydrothermal to magmatic processes. We study here melt inclusions trapped in plagioclase phenocrysts in a

Magnetite-apatite deposits are important sources of iron and other metals. A prominent example 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-r
