Abstract Magmatic volatile phases play a major role in igneous systems, but indirect sampling of the magmatic fluid, especially for basic magmas, remains challenging to document. Here, we report compelling evidence of primary fluid inclusions trapped

The critical role of magma degassing in sulphide melt mobility and metal enrichment
Autor: Giada Iacono-Marziano, Margaux Le Vaillant, Belinda M. Godel, Stephen J. Barnes, Laurent Arbaret
Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-10 (2022)
A new study shows the occurrence of a fluid phase in mafic-ultramafic magmas may represent a significant boost for magmatic sulphide ore forming processes, by favouring sulphide melt accumulation and increasing tenors.

International audience; Rare earth element (REE) enrichments in carbonatites are often described as resulting from late magmatic-hydrothermal or supergene processes. However, magmatic pre-enrichment linked to the igneous processes at the origin of ca

International audience; Nitrogen, carbon, hydrogen and sulfur are essential elements for life and comprise about 1 % of terrestrial planet masses. These elements dominate planetary surfaces due to their volatile nature, but the Earth's interior also

The critical role of magma degassing in sulphide melt mobility and metal enrichment
Autor: Giada Iacono-Marziano, Margaux Le Vaillant, Belinda M. Godel, Stephen J. Barnes, Laurent Arbaret
Publikováno v: Nature communications. 13(1)
Much of the world’s supply of battery metals and platinum group elements (PGE) comes from sulphide ore bodies formed in ancient sub-volcanic magma plumbing systems. Research on magmatic sulphide ore genesis mainly focuses on sulphide melt-silicate

International audience; Most of the intrusions in the Noril’sk-Talnakh region (Siberia) are hosted in thick sedimentary sequences including abundant evaporitic and terrigenous sedimentary rocks. Three mafic-ultramafic intrusions in this region cont

Mafic magma as metal source for Sb-W-Hg mineralisation? A case study of the early Carboniferous mafic magmatic event from the French Armorican Variscan belt

A possible genetic link between Sb-W-Hg mineralisation (vein-type and stratabound) and mafic magmatism has been proposed for the Variscan belt during the early Carboniferous, but this hypothesis remains to be rigorously assessed. The metal enrichment

Magmatic heat sources allow hydrothermal fluids to transport and deposit various types of metals and metalloids. For instance, antimony (Sb) is frequently spatially associated with mafic intrusions, and may be associated with various amounts of other
