Andreas Dietrich
Geólogo (Dipl. Geol., Dr. rer. nat.)
Dietrich Consulting E.I.R.L. es una empresa de responsabilidad limitada registrada en Santiago de Chile que brinda servicios de mapeos geológicos y soluciones SIG para la industria minera.
Andreas Dietrich es un geólogo con mas de 30 años de experiencia internacional en la exploración minera y investigaciones científicas relacionadas, mayormente en depositos epitermales a ambientes de pórfidos en America Latina y alrededor del cinturón del Pacifico. Experimentado en la exploración por vetas epitermales Au-Ag y Ag-BM, sistemas epitermales HS, ambientes de litocapas, pórfidos de Cu-Mo, Au-Cu y Sn-W-Ag, sistemas hospedadas por diatremas / complejos de breccias, ambientes de sistemas IOCG.
Servicio de mapeos geológicos: Los servicios incluyen el trabajo geológico en terreno y/o en base de imágenes satelitales, su digitalización en SIG (Sistema de Información Geográfica) más su respectiva interpretación. Tipicamente se combinan el mapeo con otros datos de exploración (geoquímica, datos hiper-espectrales, hojas geológicas, datos geo-cronológicas etc.) para su interpretación en el contexto geológico.
Cursos de mapeos geológicos: Se ofrecen cursos de mapeos geológicos que cubren desde aspectos técnicos-teóricos hasta entrenamiento en terreno. Mas información se encuentra en pagina a parte.
