Hydrothermal sulfide chimneys located along the global system of oceanic spreading centers are habitats for microbial life during active venting. Hydrothermally extinct, or inactive, sulfide deposits also host microbial communities at globally distributed sites. The main goal of this study is to describe Fe transformation pathways, through precipitation and oxidation-reduction (redox) reactions, and examine transformation products for signatures of biological activity using Fe mineralogy and stable isotope approaches. The study includes active and inactive sulfides from the East Pacific Rise 9 degrees 50'N vent field. First, the mineralogy of Fe(III)-bearing precipitates is investigated using microprobe X-ray absorption spectroscopy (RXAS) and X-ray diffraction (mu XRD). Second, laser-ablation (LA) and micro-drilling (MD) are used to obtain spatially-resolved Fe stable isotope analysis by multicollector-inductively coupled plasma-mass spectrometry (MC-ICP-MS). Eight Fe -bearing minerals representing three mineralogical classes are present in the samples: oxyhydroxides, secondary phyllosilicates, and sulfides. For Fe oxyhydroxides within chimney walls and layers of Si-rich material, enrichments in both heavy and light Fe isotopes relative to pyrite are observed, yielding a range of delta Fe-57 values up to 6 parts per thousand. Overall, several pathways for Fe transformation are observed. Pathway 1 is characterized by precipitation of primary sulfide minerals from Fe(II)aq-rich fluids in zones of mixing between vent fluids and seawater. Pathway 2 is also consistent with zones of mixing but involves precipitation of sulfide minerals from Fe(II)aq generated by Fe(III) reduction. Pathway 3 is direct oxidation of Fe(II) aq from hydrothermal fluids to form Fe(III) precipitates. Finally, Pathway 4 involves oxidative alteration of pre-existing sulfide minerals to form Fe(III). The Fe mineralogy and isotope data do not support or refute a unique biological role in sulfide alteration. The findings reveal a dynamic range of Fe transformation pathways consistent with a continuum of micro-environments having variable redox conditions. These micro-environments likely support redox cycling of Fe and S and are consistent with culture-dependent and -independent assessments of microbial physiology and genetic diversity of hydrothermal sulfide deposits.

Actualmente, las barreras comerciales a nivel internacional resultan cada vez menos tangibles entre los diferentes mercados, haciendo que las oportunidades de comercialización de bienes y servicios entre países sea cada vez mayor. Sin embargo, es muy común todavía encontrarse con historias de fracaso en los esfuerzos de diferentes empresarios medianos y pequeños que en su momento decidieron emprender el camino de la internacionalización de sus compañías y que por diferentes factores, bien sea desconocimiento de leyes comerciales internacionales, desinformación primordial del mercado objetivo o simplemente por situaciones ajenas a ellos sufrieron esta adversidad y dejaron de lado su impulso e interés por internacionalizarse. Por tal razón, hemos enfocado nuestros esfuerzos en tratar de identificar las diferentes potencialidades y oportunidades que el empresario colombiano puede llegar a tener en cuatro estados de Estados Unidos de Norteamérica, Nueva York, Nueva Jersey, Nuevo Hampshire y Nebraska específicamente. La metodología a desarrollar a lo largo de esta investigación principalmente recoge información cualitativa y cuantitativa que nos permitirá desglosar diversos aspectos con mayor profundidad, para que el empresario interesado tenga un panorama más claro de lo que puede llegar a encontrarse en los estados mencionados anteriormente.
