Industrial and natural sources of gaseous elemental mercury in the Almadén district (Spain): an updated report on this issue after the ceasing of mining and metallurgical activities in 2003 and major land reclamation works.
Two events during the last decade had major environmental repercussions in Almadén town (Spain). First it was the ceasing of activities in the mercury mine and metallurgical facilities in 2003, and then the finalization ...
Low-cost geochemical surveys for environmental studies in developing countries: testing a field portable xrf instrument under quasi-realistic conditions.
Environmental monitoring, as a prerequisite for environmental risk assessment, is crucial in developing nations from Africa, Latin America, South East Asia, or Melanesia, where conspicuously most of the Worlds mining ...
An estimation of mercury concentrations in the local atmosphere of Almadén (Ciudad Real Province, South-Central Spain) during the 20th Century.
We show the first estimations of long-term (100 years, 1900 to 2000) total gaseous mercury concentrations (TGM) in the urban area of Almadén. The estimation was carried out by comparing data on known metallic mercury ...
Environmental assessment of the arsenic-rich, rodalquilar gold-(copper-lead-zinc) mining district, se Spain: soils and wild plants species.
The Rodalquilar mineral deposits (SE Spain) were formed in Miocene time in relation to caldera volcanic episodes and dome emplacement phenomena. Two types of ore deposits are recognized: (1) the El Cinto epithermal, Au?As ...
Intraplate mafic magmatism, degasification, and deposition of mercury: the giant Almadén mercury deposit (Spain) revisited
The giant Almadén mercury deposit (Spain) is hosted by the Lower Silurian Criadero Quartzite; in turn this ore-bearing rock unit is cross-cut by the so-called Frailesca unit, a diatreme body of basaltic composition. The ...
The mazarrón pb-(ag)-zn mining district (se Spain) as a source of heavy metal contamination in a semiarid realm: geochemical data from mine wastes, soils, and stream sediments.
The Mazarrón epithermal ore deposits (SE Spain) formed in Miocene time in relation to the emplacement of dacitic?rhyodacitic domes. The Pb-(Ag)-Zn ore deposits are of the high sulphidation vein and stockwork type. There ...
