RT Journal Article T1 Presencia de Cloritoide en las pizarras ordovícicas del sinforme de Alcañices (Zamora) T1 Presence ofchloritoid in the ordovician slates of the Alcañices synform (Zamora) A1 Fernández Fernández, A. A1 Moro Benito, M. C. AB In the present work we describe for the first time the presence of chloritoid associated with slates of Llanvirn-Llandellian age (Latedo Formation) o f the southern flank of the Alcahices Synform (Zamora).Usually this mineral metamorphic appears in islated prismatic crystals or forming aggregates that are radial, parallel or oblique to the SI and S3 schistosity of the slates. Analysis by electronic microprobe, EDAX and X-ray difraction (XRD) indicates that these chloritoids belong to the ferrous variety, with low MgO contents and without zoning or appreciable differences among the crystals and they mainly correspond to the triclinic polytype PB Sociedad Geológica de España YR 1993 FD 1993 LK http://hdl.handle.net/10272/14055 UL http://hdl.handle.net/10272/14055 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
