Precipitation/dissolution of marine evaporites as determinants in groundwater chemistry in a salt marsh (Península Valdés, Argentina)
(Elsevier Science, 2016-11)
Evaporites are mineral facies frequently occurring in salt marsh environments in arid climates. Considering that groundwater and soil salinity play an important role in the development of salt marsh ecosystems, the aims ...
Application of Synthetic Rock Mass modeling to veined core-size samples
(Elsevier, 2016)
Rock masses of the primary copper ore at the El Teniente mine fail mainly through the infill of preexisting veins during the caving processes, especially through those composed of less than 35% hard minerals (quartz and ...
A late quaternary paleoenvironmental record in sand dunes of the northern Atacama desert, Chile
(Cambridge University Press, 2018-07)
This paper reports a previously unidentified paleoenvironmental record found in sand dunes of the Atacama Desert, Chile. Long-term aeolian deflation by prevailing onshore winds has resulted in the deposition of sand on the ...
Observations on trace element hypersaline geochemistry in surficial deposits of evaporation ponds of Exportadora de Sal, Guerrero Negro, Baja California Sur, México
(Marine Chemistry, 2002)
Trace element concentrations were determined for 28 samples of surficial deposits collected over a salinity gradient of 39‰ to approximately 250‰ in evaporation ponds of a large industrial NaCl production facility located ...
Propiedades físico-químicas de las aguas minerales y origen de su composición
(Editora Geotech, 2004)
Las aguas naturales adquieren su composición química mediante un proceso complejo, donde intervienen factores de tipo químico-físico, geológico, hidrogeológico, geomorfológico, pedológico, climático, antrópico y otros ...
Non-Classical Types of Loess
(Elsevier Science, 2007-12)
The purpose of this contribution is to describe the sequence of physical and chemical processes resulting in the sediment-type named loess, a fine-grained sediment deposit of universal occurrence. Owing to historical causes, ...
Aplicação de espectrometria de massa com ionização paper spray em análises de cunho forense e no monitoramento e aceleração de reações quimicas
(Universidade Federal de Minas GeraisUFMG, 2018-07-17)
The present work employed the analytical technique denominated Paper Spray Mass Spectrometry (PS-MS) in two distinct themes of high current relevance: forensic analyses and monitoring and acceleration of chemical reactions. ...
