Metals in the particulate matter from surf zone waters of a Southwestern Atlantic sandy beach (Monte Hermoso, Argentina)
(Elsevier, 2019-05-25)
Cd, Cr, Cu and Pb were analyzed for the first time in the suspended particulate matter (SPM) in surf zone waters of a sandy beach located in the Southwestern Atlantic. The study area corresponds to a recreational sandy ...
Trace metals in pyrite and marcasite from the Agua Rica porphyry-high sulfidation epithermal deposit, Catamarca, Argentina: Textural features and metal zoning at the porphyry to epithermal transition
(Elsevier Science, 2015-04)
Agua Rica is a world-class Cu (Mo-Au) deposit located in Catamarca, Argentina, in which the porphyry and high sulfidation epithermal stages are juxtaposed due to the telescoping of the mineralizing system. Pyrite is the ...
Metabolic and physiological responses of a coastal fish in highly and lightly impacted habitats
(Elsevier Science, 2020-12-09)
Coastal and estuarine zones are used by fish as nursery, spawning and feeding grounds. However, these essential habitats are characterized by the presence of both natural and anthropogenic stressors that may represent ...
Heavy metal concentrations in water and sediments from affluents and effluents of mediterranean chilean reservoirs
(Sociedad Chilena Química, 2016)
RIVER flows have constant interaction between water and bed sediments; for this reason knowledge of the characteristics of the sediments is fundamental to understand water chemistry. This study determined the concentrations ...
Copper-arsenic decoupling in an active geothermal system: a link between pyrite and fluid composition
(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 ...
