dc.description.abstractScapolites are present in some doleritic tectonic blocks C'ophites" )in the External Zones o f the Betic Cordilleras, In Northern of Cadiz province. These scapolites fill veinlets and replace plagioclases from the dolerites in the proximity of fissures. Scapolites (Me262g) are partial or totally replaced by low-iron prehnites (XFe3+ = 0.13-0. 66). Fluid inclusions found in scapolites show high salinity (40-55% wt. eq.) multications (Na-Ca-K.?) aqueous fluids. No volatil phases has been detected in microthermometric runs. Temperatures of homogeneization range from 380 to 540°C. These scapolites filling dolerite veinlets are interpreted as a result of magma-evaporite Interactions during dolerite emplacement into the Triassic evaporitic formationsen_US
