    • Constraints on the solid solubility of Hg, Tl, and Cd in arsenian pyrite 
      Deditius, Artur P.; Reich Morales, Martín (Mineralogical Society of America, 2016)
      Arsenic-rich (arsenian) pyrite can contain up to tens of thousands of parts per million (ppm) of toxic heavy metals such as Hg, Tl, and Cd, although few data are available on their solid solubility behavior. When a compilation ...
    • Copper-arsenic decoupling in an active geothermal system: a link between pyrite and fluid composition 
      Tardani, Daniele; Reich Morales, Martín; Deditius, Artur P.; Chryssoulis, Stephen; Sánchez Alfaro, Pablo; Wrage, Jackie; Roberts, Malcolm P. (Elsevier, 2017-05-01)
      Over the past few decades several studies have reported that pyrite hosts appreciable amounts of trace elements which commonly occur forming complex zoning patterns within a single mineral grain. These chemical zonations ...
    • Formation of massive iron deposits linked to explosive volcanic eruptions 
      Ovalle, J. Tomás; La Cruz, Nikita L.; Reich Morales, Martín; Barra, Fernando; Simon, Adam C.; Konecke, Brian A.; Rodriguez-Mustafa, María A.; Deditius, Artur P.; Childress, Tristan M.; Morata Céspedes, Diego (Nature Publishing Group, 2018)
      © 2018, The Author(s). The genetic link between magmas and ore deposit formation is well documented by studies of fossil hydrothermal systems associated with magmatic intrusions at depth. However, the role of explosive ...
    • Geochemical and micro-textural fingerprints of boiling in pyrite 
      Román, Nelson; Reich Morales, Martín; Leisen, Mathieu; Morata Céspedes, Diego; Barra, Fernando; Deditius, Artur P. (Elsevier Ltd, 2019)
      © 2018 Elsevier Ltd The chemical composition, textures and mineral associations of pyrite provide key information that help elucidate the evolution of hydrothermal systems. However, linking the compositional and micro-textural ...
    • Magmatic platinum nanoparticles in metasomatic silicate glasses and sulfides from Patagonian mantle xenoliths 
      González-Jiménez, José María; Roqué-Rosell, Josep; Jiménez-Franco, Abigail; Tassara, Santiago; Nieto, Fernando; Gervilla, Fernando; Baurier, Sandra; Proenza, Joaquín A.; Saunders, Edward; Deditius, Artur P.; Schilling, Manuel E.; Corgne, Alexandre (Springer Verlag, 2019)
      Platinum-rich nanonuggets (s.l., nanoparticles) are commonly produced in experiments attempting to quantify the solubility or partitioning of noble metals in silicate and sulfide melts. However, it has been thought that ...
    • Nanogeochemistry of hydrothermal magnetite 
      Deditius, Artur P.; Reich Morales, Martín; Simon, Adam C.; Suvorova, Alexandra; Knipping, Jaayke; Roberts, Malcolm P.; Rubanov, Sergey; Dodd, Aaron; Saunders, Martin (Springer, 2018-06)
      Magnetite from hydrothermal ore deposits can contain up to tens of thousands of parts per million (ppm) of elements such as Ti, Si, V, Al, Ca, Mg, Na, which tend to either structurally incorporate into growth and sector ...
    • New contributions to the understanding of Kiruna-type iron oxide-apatite deposits revealed by magnetite ore ... 
      Rojas, Paula A.; Barra Pantoja, Luis Fernando; Deditius, Artur; Reich Morales, Martín; Simon, Adam; Roberts, Malcolm; Rojo, Mario (Elsevier, 2018)
      Iron oxide-apatite (IOA) or Kiruna-type deposits are an important source of iron and other elements including REE, U, Ag, and Co. The genesis of these deposits remains controversial, with models that range from a purely ...
    • Trace element signature of pyrite from the los colorados iron oxide-apatite (ioa) deposit, chile: a missing ... 
      Reich Morales, Martín; Simon, Adam C.; Deditius, Artur P.; Barra, Fernando; Chryssoulis, Stephen; Lagas, Gonzalo; Tardani, Daniele; Knipping, Jaayke L.; Bilenker, Laura; Sánchez Alfaro, Pablo (Soc Economic Geologists, 2016)
      Although studies have proposed that iron oxide-apatite (IOA) deposits may represent the deeper roots of some Andean iron oxide copper-gold (IOCG) systems, their genetic links remain obscure and controversial. A key ...
