  abstract = {{S}tudies of mafic dyke swarms may simultaneously provide information on the mechanical, geochemical, geochronological and magnetic environments at the time of their formation. {T}he mafic intrusive history of different cratons can also be potentially used to unravel their assembly into their current configuration. {T}he identification and classification of dykes is a first step to all these studies. {F}ortunately, even in regions with poor outcrop, we can use the strong magnetic response of mafic dykes to identify and map their extent. {I}n {W}est {A}frica the first maps of mafic dyke distribution were made over 40 years ago, but there are still large areas where there are almost no published data. {I}n this paper we present a significantly updated map of mafic dykes for the {W}est {A}frica {C}raton based in large part on new interpretations of the regional airborne magnetic database. {T}his map includes the locations of over three thousand dykes across the craton, which locally shows several orientation clusters that provide a minimum estimate for the total number of dyke swarms in this region. {W}hilst we will have to wait until systematic dating of the different swarms is completed, we can demonstrate that there is a long and complex history of mafic magmatism across the craton, with up to 26 distinct dyke swarms mapped based according to their orientation. {T}he mapping and dating of these swarms will provide key constraints on the assembly of the fragments that make up the modern continents.},
