..., their geochemical composition indicates an origin from a primary komatiitic magma, with a melting temperature of 1700 °C at a depth of 150 km. Similarities in the petrology and age (88–90 Ma) of Gorgona, Curaìao, and Nicoya-Tortugal mafic and ultramafic volcanic rocks suggest that these rocks had a common origin...

...., 2000b ). Given their chemistry ( Figures 3d , 4d , and 6a ) and their age, these rocks are interpreted as representing parts of the CCOP. At Tortugal, a suite of more enriched basalts is very similar to the trace element–enriched basalts of Site 151 and some other enriched basalts from the province...

.... (2000) , who analyzed samples from other localities of the Manzanillo Terrane. In comparison, the Tortugal alkaline suite presents steeply inclined trace element patterns displaying U-Th negative anomalies relative to Nb ( Fig. 12A ), enrichments in light rare earth elements (LREE), as well as higher Nb...

... mainly of a peridotitic body, cut by a number of doleritic dykes and with subordinate breccias, thrusted onto basaltic rocks in the southwesternmost part of the peninsula. The Nicoya complex consists of an intrusive suite (gabbros, Fe-gabbros, Fe-diorites and plagiogranites) and basaltic rocks (basalts...
