An ancient Ba-Sb-Ag-Fe-Hg-bearing hydrothermal system in SE Spain

Abstract: characteristic of the Neogene-Quaternary volcanic province of SE Spain is its spatial and temporal relationship with gold, silver, Fe-Mn, Hg-Sb, and base-metal sulphide hydrothermal mineralization. All these deposits comprise a metallogenetic belt, which extends from the Cabo de Gata Natural Park (Almeria province) to Cartagena (Murcia province). With the exception of the famous gold-rich volcanic area of Rodalquilar, the hydrothermal systems of SE Spain are represented by the mineral deposits rich in Ba-Sb-Ag… Show more

“…Epithermal ore deposits are hosted by intermediate to acid volcanics ranging in age from 12 to 10 Ma; these deposits are found in a number of different mining districts, for example Zn-Pb-Cu(-Ag-Au) at San Jos e (Demoustier et al 1998;Esteban-Arispe et al 2009), Au(-Cu-Te-Sn) at Rodalquilar (Arribas et al 1995) and Cu-Au-Ag at Carboneras (Morales Ruano et al 2000;Carrillo-Ros ua et al 2009). Ba-Ag mineralization is found in sedimentary rocks, close to high-K calcalkaline and shoshonitic volcanics within the Vera Basin (Alvado 1986;Mart ınez-Fr ıas 1998). Certain ore deposits are hosted by metamorphic rocks, including the occurence of Pb-Zn-Fe-Cu (Al) at Cartagena (Graeser & Friedrich 1970;Oen et al 1975;Arribas et al 1983) and Pb-Zn-Ag-Fe at Sierra Almagrera and Sierra Aguilon (Martinez Frias et al 1989;Morales Ruano et al 1993).…”

“…El depósito presenta contenidos elevados en manganeso (hasta 62.8% en peso de MnO) y en bario (hasta 4500 ppm), y bajas concentraciones en metales de transición (Co+Ni+Cu < 0.01% en peso). En relación a la provincia volcánica de edad neógena a cuaternaria del SE de España se han descrito mineralizaciones estratoligadas con Ba-Sb-Ag-Fe-Hg en Las Herrerías y Valle del Azogue, en las que se han reconocido estructuras equiparables a chimeneas mineralizantes fósiles (Martínez-Frías, 1998). Estas mineralizaciones tienen potencias de hasta 10 m y están constituidas por cuerpos de barita y jaspe con óxidos e hidróxidos de Fe y Mn, pirita, esfalerita, galena, cinabrio y plata nativa diseminados.…”

“…Además, los manantiales hidrotermales someros pueden considerarse como laboratorios naturales para el estudio de la interacción entre los fl uidos hidrotermales (agua y gas), los sedimentos y las rocas del fondo marino, y el agua de mar (e. g., Fitzsimons et al, 1997;Botz et al, 1999;Pichler et al, 1999a;Prol-Ledesma et al, 2004;Chen et al, 2005;Forrest et al, 2005;Villanueva-Estrada et al, 2005y 2006. En general, los fl uidos descargados por los manantiales someros son de menor temperatura que los que se registran en los de gran profundidad, aunque tienen capacidad para transportar metales en cantidades sufi cientes como para generar acumulaciones de óxidos, sulfuros y metales preciosos (Martínez-Frías, 1998;Stoffers et al, 1999;Hein et al, 2000;Prol-Ledesma et al, 2002a;Canet et al, 2005b;Jach y Dudek, 2005). Los mecanismos de precipitación de minerales alrededor de zonas de emisión hidrotermal en ambientes submarinos de poca profundidad han sido objeto de diversos estudios (Pichler et al, 1999b;Stoffers et al, 1999;Prol-Ledesma et al, 2002a;Canet et al, , 2005aAlfonso et al, 2005).…”
