According to these data, it is suggested that these tourmalinites has been originated by regional metamorphisme of the B-rich pelitic beds. The B were probably trought to the sediment by the hidrothermal solutions related with the underlayžng metabasaltic rocks existing in the studied areaspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Stratiforme tourmalinitesLower OrdovicianRegional metamorphismeMetabasaltic rocksjournal articleopen access
