15 p, 448.1 KB Red rains as major contributors of nutrients and alkalinity to terrestrial ecosystems at Montseny (NE Spain) / Àvila i Castells, Anna (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Rodà, F. (Ferran), 1953- (Centre de Recerca Ecològica i d'Aplicacions Forestals)
During two years (1983-1985), 8 red rains were collected in the Montseny mountains. The suspended matter contained in red rains has its source in the Sahara desert and corresponds to fine silts. Due to the calcite content of dust responsible for the red rains, these rains are alkaline with a volume weighted mean pH of 7. [...]
Durant dos anys (1983-1985) es varen recollir 8 pluges de fang a La Castanya (Montseny). La matèria particulada de les pluges de fang s'origina al desert del Sahara, i correspon a llims fins. Degut al contingut de calcita d'aquests llims, les pluges de fang són alcalines, amb un pH mig de 7. [...]

23 p, 115.4 KB Las lluvias de barro y el transporte y deposición de material sahariano sobre el nordeste de la península Ibérica / Àvila i Castells, Anna (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Se describe la composición mineralógica y elemental del contenido particulado de las lluvias de barro recogidas en el Montseny (nordeste península Ibérica) desde 1983 a 1998. Se han identificado 3 áreas-fuente en el norte de África: el Sahara occidental, el Atlas marroquí y el Sahara central. [...]
The African dust frequency, dust content, dust mineralogy and elemental composition have been analyzed for a site in the Montseny mountains (northeastern Spain) for the period 1983-1998. Three source regions in North Africa have been identified for the dust loaded red rains: Western Sahara, Moroccan Atlas and central Sahara. [...]
