In both cases the chert is located at the top of acidic volcanic sequences or in the associated sediments; we have not been able to observe the relationships between massive sulphides and chert, but some of the large orebodies of the Province (Lousal, La Zarza, Tharsis, Planes-San Antonio body of Rio Tinto, Neves) are described as being locally capped by chert facies.

El chert se localiza en los dos casos en el techo de las secuencias volcánicas ácidas o en los sedimentos asociados. No hemos podido observar las relaciones entre sulfuros masivos y chert, pero se ha descrito que algunas de las mayores masas de la provincia (Lousal, La Zarza, Tharsis, Planes-San Antonio en Ríotinto, Neves) están localmente recubiertas por facies de chert.
