The Moroccan Variscan orogen contains numerous small felsic magmatic bodies from the Upper Neoproterozoic. The Tiflet granitoids (Northwestern Moroccan Meseta) consist of two lenticular bodies (Taicha and Sidi BouJemaa) with granodioritic composition

One of the most characteristic attributes of pegmatitic rocks is their anisotropic fabric with a great variety of textures, including not only a broad range of crystal sizes, but also different types of unidirectional crystal growths such as the so-c

Apatite can be used as an archive of processes occurring during the evolution of granitic magmas and as a pegmatite exploration tool. With this aim, a detailed compositional study of apatite was performed on different Variscan granites, pegmatites an

A new type of Li mineralisation in hard rock has been found to occur in the Valdefórez area (Cáceres, Spain), where there is 111.3 Mt of resources and a mean value of 0.61 wt% of Li2O. Lithium is mainly held by very fne-grained micas, important con

The aim of this study is to establish the petrogenetic links between the different granitic and aplopegmatitic units occurring in the Tres Arroyos granite-aplopegmatite system (Central Iberian Zone, Spain), from the textural and chemical variations i
