Abstract

Eight different generations of dolerite dykes crosscutting the Paleoproterozoic basement in West Africa and one in South America were dated using the high precision U–Pb TIMS method on baddeleyite. Some of the individual dykes reach over 300Â km in length and they are considered parts of much larger systems of mafic dyke swarms representing the plumbing systems for large igneous provinces (LIPs). The new U–Pb ages obtained for the investigated swarms in the southern West African Craton (WAC) are the following (oldest to youngest): 1791 ± 3Â Ma for the N010° Libiri swarm, 1764 ± 4Â Ma for the N035° Kédougou swarm, 1575 ± 5 for the N100° Korsimoro swarm, ~1525–1529Â Ma for the N130° Essakane swarm, 1521 ± 3Â Ma for the N90° Sambarabougou swarm, 915 ± 7Â Ma for the N070° Oda swarm, 867 ± 16Â Ma for the N355° Manso swarm, 202 ± 5Â Ma and 198 ± 16Â Ma for the N040° Hounde swarm, and 200 ± 3Â Ma for the 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 intrusionÂ in Guinea. In addition, the N150° Käyser swarm (Amazonian craton, South America) is dated at 1528 ± 2Â Ma, providing a robust match with the Essakane swarm in a standard Amazonia-West African craton reconstruction, and resulting in a combined linear swarm >1500Â km by >1500Â km in extent. The Precambrian LIP barcode ages of c. 1790, 1765–1750, 1575, 1520, 915. 870Â Ma for the WAC are compared with the global LIP record to identify possible matches on other crustal blocks, with reconstruction implications. These results contribute to the refinement of the magmatic ‘barcode’ for the West African and Amazonian cratons, representing the first steps towards plausible global paleogeographic reconstructions involving the West African and Amazonian cratons.

We would like to acknowledge the mining companies who provided the necessary on-site logistics and let us acquire samples from their sites: SEMAFO Inc. for access to the Libiri pit, IAMGOLD Corp. for access to the Essakane mine, High River Gold Mines Ltd. for access to the Taparko mine, Etruscan Mining Corporation for access to Youga mine. We would like to thank for the logistical support to the IRD center in Ouagadougou and to Moumouni Kone. The research was co-financed by the West African Exploration Initiative (WAXI). We wish to acknowledge AMIRA International and the industry sponsors, including AusAID and the ARC Linkage Project LP110100667, for their support of the WAXI project (P934A). The field work was co-financed by Centre National de la Recherche Scientifique—Institut National des Sciences de l’Univers SYSTER research grant. Special thanks to Laurent Aillères for posing as a scale. Sergei Pisarevsky is also appreciated for discussion of some paleomagnetic implications.

We appreciate the comments from Reviewers 1 and 2 which led to important improvements in the manuscript. In particular we thank Reviewer 1 for the suggestion that the Mesozoic Taiano and Uaraná dyke swarms in South America (Brazil) are potentially matching in age to the CAMP age Hounde swarm.
