Andreas Flitner,Christian Petry,Ingo Richters with synchronous lithosphere extension during the two time periods. 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. They show tholeiitic chemistry and similarities with E-MORB and subcontinental lPanther 发表于 2025-3-25 12:16:21

Jürgen Oßenbrügge,Susanne Heeg,Britta Klagge sills in the Taoudeni basin. 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低三下四之人 发表于 2025-3-25 23:49:05
