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

Cracking of Gem Opals

Volume 13
Issue 3
Pages: 356

The value of gem opals is compromised by their potential susceptibility to “crazing”, a phenomenon observed either in the form of whitening or cracking. To understand the latter, 26 opal samples were investigated and separated into 2 groups based

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

Unravelling the relationship between mafic magmatism and Sb mineralization through dolerite geochemistry (Central Iberian Zone, Spain)

Autor: Giada Iacono-Marziano, Valentin Mollé, José María Esbrí, Pablo Higueras, Eric Gloaguen, Saturnino Lorenzo, Héctor Ricardo Campos Rodríguez, Anthony Pochon

This work presents the preliminary results of geochemistry of mafic intrusions (diabase dykes) and their relationship with antimony mineralization in the Central-Iberian Zone (Variscan Belt). Two different areas were studied, the Almadén (Al) and th

Crystallisation sequence of a REE-rich carbonate melt: an experimental approach

Autor: Valentin Mollé, Fabrice Gaillard, Zineb Nabyl, Johann Tuduri, Ida Di Carlo, Saskia Erdmann

Carbonatites host the main REE deposits in the world, with bastnaesite being the main REE-bearing mineral of interest. However, the nature of the enrichment process, magmatic vs hydrothermal, is still debated. This study aims to experimentally determ

Lasnierite, (Ca,Sr)(Mg,Fe)(2)Al(PO4)(3), is a new phosphate mineral from Mt. Ibity, close to Itremo, central Madagascar. The mineral was found as inclusions accompanying blue lazulite and many other minerals in blue metaquartzite occasionally used as
