Abstract
⺠First documented occurrence of Fe-rich tholeiitic basalts in Guiana Shield of South America. ⺠First documented occurrence of primitive mantle basalt in an oceanic plateau in South America. ⺠Basalt in the Guasipati-El Callao Greenstone Belt is Fe-rich tholeiite. ⺠Basalt in the Guasipati-El Callao Greenstone Beltis formed in an oceanic plateau setting, from a primitive mantle plume. ⺠Volcanic rocks in the Guasipati-El Callao Greenstone Belt have an elevated potential for hosting gold mineralization.
