Resumen de Relaciones genéticas entre las turmalinitas estratiformes y los basaltos toleíticos Ordovícicos de Latedo (Zamora)
The spatial and genetic relationships between stratiforms tourmalinites and tholeiitic basalts, found interstrafied in the Middle Member of the Lower Ordovician "Cabeza de las Viñas Formation" are described in the study. The genesis of the stratiform tourmalintes is modelized based in those relationships. It is suggested that in the Alcañices Symform as well as elsewhere in the world, the association of there two rock types can be used as a prospecting guide to located massive sulphide deposits.
