Tesis doctoral de Susana Mar\u00eda Timon Sanchez <\/strong><\/h2>\n

El skarn c\u00e1lcico y reducido de scheelita de los santos es el resultado de la alteraci\u00f3n metasom\u00e1tica de los metasedimentos del c\u00e1mbrico inferior (formaci\u00f3n calizas de tamames) y las granodioritas – monzogranitos del extremo occidental del batolito de \u00e1vila por la acci\u00f3n de soluciones hidrotermales durante la \u00e9poca tardivarisca. la intrusi\u00f3n de los granitoides origin\u00f3 un metamorfismo de contacto acompa\u00f1ado de metasomatismo sin mineralizaci\u00f3n. Las condiciones termobarom\u00e9tricas de este evento, entre 2 y 2,5 kb y entre 630 y 640\u00c2\u00bac, reflejan un ambiente mesozonal para el inicio de la formaci\u00f3n del dep\u00f3sito, que se caracteriza por el desarrollo de un exoskarn de hedembergita-grosularia-scheelita y un endoskarn de plagioclasa c\u00e1lcica-clinopiroxeno-granate. El endoskarn se genera sobre un granito apl\u00edtico cuya edad de emplazamiento se ha estimado en 307\u00c2\u00b120 ma. Para el primer estadio se han obtenido edades entre 270 y 287\u00c2\u00b120 ma. las fases minerales hidratadas y las evidencias de fracturaci\u00f3n hidr\u00e1ulica (stockscheider y fen\u00f3menos de ebullici\u00f3n e inmiscibilidad) implican un descenso de la presi\u00f3n de fluidos (pf<1kb; t=439-410\u00c2\u00bac) ligado a la retrogradaci\u00f3n (250\u00c2\u00b120 ma). El responsable de la apertura del sistema es un granito que no aflora. la evoluci\u00f3n del skarn en t\u00e9rminos de su potencial de oxidaci\u00f3n discurre desde un tipo reducido, pr\u00f3ximo al tamp\u00f3n qfm, hasta desarrollar facies oxidantes. La fs2 refleja un tamponamiento externo impuesto por el fluido mineralizador. La trayectoria del fluido corresponde a un enfriamiento con xco2 decreciente. el desarrollo del skarn representa la evoluci\u00f3n de un sistema magm\u00e1tico-hidrotermal. En este modelo, los fluidos acuoso-carb\u00f3nicos fueron exsueltos del complejo plut\u00f3nico durante su emplazamiento y cristalizaci\u00f3n. La progresiva interacci\u00f3n de estos fluidos con las pizarras negras del complejo esquisto-grauv\u00e1quico contribuy\u00f3 a aumentar el contenido en gases como el ch4 constituyendo as\u00ed el fluido mineralizador que formar\u00eda el skarn de scheelita\n\n\n\n \n\n\n
