[ES]: En este trabajo se estudia la presencia de caolinita (materia prima de interés cerámico) en varios cortes desarrollados sobre granitos y pizarras situados en la sierra de Huelva. Los cortes desarrollados sobre granitos (situados en Santa Olalla y Cala), alcanzan un contenido en caolinita entre un 60% y un 70%, En los cortes desarrollados sobre pizarras (situados en Galaroza y Almonaster), la caolinita llega a estar presente en proporciones del 80%. Acompañando a la caolinita aparece siempre ilita, estando presente además mineral con aluminio interlaminar. De acuerdo con los resultados obtenidos, el mineral caolinita hace más patente su presencia en los estratos más profundos. En estos materiales es de señalar la existencia de óxidos de hierro, que pueden perjudicarlos para aplicaciones de tipo industrial. Las muestras situadas en Galaroza y Almonaster se consideran las de mayor interés cerámico y contenido en fracción <20µm así como su riqueza en mineral caolinita.
[EN]: This paper studies kaolinite presence (raw material with ceramic interest) in some stints developed from granite and shale placed in Huelva Mountains. Stints developed from granite (placed in Santa Olalla and Cala), reach contents in kaolinite in a range between 60% and 70%. In the stints developed from shale (placed in Galaroza and Almonaster), kaolinite is always found; in addition to the presence of aluminium-interlayer mineral. In accordance with the obtained results, kaolinite mineral is more frequent in the deepest stints. In these materials, the existence of iron oxides must be point out, adding that they can damage the above mentioned materials when having industrial applications. Samples placed in Galaroza and Almonaster are considered those with the highest ceramic interest because of their power and content in fraction <20µm as well as their richness in kaolinite mineral.
