Giant Circumferential Dyke Swarms: Catalogue and Characteristics,largest giant circumferential swarms have diameters comparable to the diameters postulated for the flattened heads of plumes that have risen from the core-mantle boundary, suggesting that they may be associated with the outer edge of a flattening or flattened mantle plume head. Smaller giant circumf

The Avanavero (1.79 Ga) LIP event mostly consists of mafic dykes and sills which are intrusive into the Roraima platform cover, in the Guiana Shield.

The last ones are related to the Central Atlantic Magmatic Province (CAMP) event. The Hounde swarm is oblique to the dominant radiating CAMP swarm and may be linked with the similar-trending elongate Kakoulima intrusion in Guinea. In addition, the N150° Käyser swarm (Am

Geochemistry, Petrogenesis and Tectonic Significance of the Proterozoic Mafic Dykes from the Bomdil0.15–16.42) ratios indicate that these rocks were probably derived from an enriched lithospheric mantle source due to varying degrees of partial melting and subsequently the melt was modified by fractional crystallization of olivine, pyroxene and plagioclase rather than crustal contamination.
