  abstract = {{T}his paper examines existing and newly compiled geophysical representations of the {W}est {A}frican {C}raton ({WAC}) in terms of its large-scale tectonic architecture. {I}n order to build an interpretation with a significant depth extent we draw upon a range of geophysical data, principally seismic tomographic inversions, receiver functions, gravity and magnetics. {W}e present these results as a series of layers providing a series of depth slices though the cratonic lithosphere. {T}he different geophysical methods suggest partitioning of the {WAC} into two tectonic elements at the largest scale which is observed in both seismic tomographic images, lithosphere-asthenosphere boundary ({LAB}) models and long wavelength gravity signals. {T}he different models of the {M}oho, or crust-mantle boundary, based on these gravity or seismic datasets show little or no correlation, either for short or long-wavelength features, and show little correlation with new receiver function inferred crustal thickness estimates. {M}anual interpretation of low-wavelength gravity and magnetic data suggest a possible continuation of the {WAC} across the western margin of the modern boundary, and also highlight distinct domains interpreted to be of {B}irimian age.},
