      © 2019In the Atacama Desert of northern Chile, large amounts of the copper hydroxy-chloride mineral atacamite (Cu2Cl(OH)3) are formed in the supergene oxidation zone of Cu deposits. Since atacamite requires saline water ...
    • Carretier, Sebastien; Godderis, Yves; Martínez Concha, Francisco; Reich Morales, Martín; Martinod, Pierre (European Geosciences Union, 2018)
      The role of mountain uplift in the evolution of the global climate over geological times is controversial. At the heart of this debate is the capacity of rapid denudation to drive silicate weathering, which consumes CO2. ...
    • 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 ...
    • 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 ...
    • Slagter, Silvina; Reich Morales, Martín; Muñoz Sáez, Carolina; Southon, John; Morata Céspedes, Diego; Barra, Fernando; Gong, Jian; Skok, J. R. (Geological Society of America, 2019)
      Silica sinter deposits overlying geothermal fields are reliable records of environmental, geochemical, and biological changes through time. Therefore, determining the absolute ages of formation of these deposits is fundamental ...
    • Tardani, Daniele; Reich Morales, Martín; Roulleau, Emilie; Takahata, Naoto; Sano, Yuji; Pérez Flores, Pamela; Sánchez Alfaro, Pablo; Cembrano, José; Arancibia, Gloria (Elsevier, 2016)
      There is a general agreement that fault-fracture meshes exert a primary control on fluid flow in both volcanic/magmatic and geothermal/hydrothermal systems. For example, in geothermal systems and epithermal gold deposits, ...
