Abstract
Se caracteriza por análisis químico, microscopía óptica, difracción de Rayos X, análisis térmico diferencial, termogravimetría y espectroscopía de infrarrojos, una zeolita fibrosa perteneciente a la formación volcánica aglomerática del Complejo Basal de la isla de Fuerteventura. Los datos analíticos obtenidos confirman la identidad de esta zeolita fibrosa como escolecita. El análisis químico del mineral pone de manifiesto un elevado contenido en sodio, superior a los que aparecen en la bibliografía para distintas escolecitas y próximo al de mesolita. Los diagramas de difracción de rayos X y análisis térmico diferencial son intermedios a los correspondientes a mesolita y escolecita. Sin embargo, las propiedades ópticas del mineral, la curva termogravimétrica y el espectro de infrarrojo son concluyentes, confirmando la identidad de esta zeolita fibrosa como escolecita.
A fibrous zeolite belonging to the agglomeratic volcanic formation is studied by means of chemical arialysis, optical microscopy, XR difraction, differential thermal analysis, thermogravimetry and infrared spectroscoP:f. The data confirm the identity of this fibrous zeolite as scolecite. The chemical analysis of this mineral reveals a Na content greater than those cited in the previous bibliographic references of scolecite and closest to the value corresponding to meso lite. The. XR Difractiondiagrams and the differential thermal analysis are intermediate between those corresponding to mesolite and scolecite. Howewer, the optical properties of the mineral, the thermogravimetric curve and the infrared spectrum are conclusive and, confirm the identity of this fibrous zeolite as scolecite
