  abstract = {{T}he {B}angui magnetic anomaly ({BMA}) in {C}entral {A}frica is one of the largest continental magnetic anomalies on {E}arth in terms of amplitude and lateral size. {D}etermining the sources of the {BMA} can lead to an increased understanding of the crustal dynamic in the {C}entral {A}frican sub -region and the {A}frican continent as a whole. {M}agnetic and gravity analysis -based derivative, two-dimensional forward modelling and a {C}urie isothermal depth, showed that (a) the bottoms of the magnetic sources were between 15 and 35 km; (b) the {BMA} is a coalescence of several anomalies that trend {E} -{W} and roughly {NE} -{SW}. {T}hese directions coincide with regional {P}an {A}frican -aged shear zones along the {C}entral {A}frican orogenic belt and to thrust sheets at the northern edge of the {C}ongo {C}raton. {T}he depth of magnetization does not exceed 35 km with the amplitude of magnetization becoming smaller in the {C}entral {A}frican {R}epublic. {T}he potential magnetic susceptibility sources have an average density of 2850 kg/m3 and magnetic susceptibilities between 0.06 and 0.25 {SI}. {T}he {BMA} is interpreted to be a combination of middle and lower crustal bodies that are not continuous and consist of magnetic mineral rich granulites and banded iron formations. {T}he gravity and magnetic modelling indicate that the entire crust was involved in the {P}an {A}frican collisional event similar to what is seen in the {M}ozambique belt in {E}ast {A}frica. {C}ombined with geological and geochemical studies, the models add evidence that one or two subduction zones were involved in accreting terranes on the northern edge of the {C}ongo {C}raton. {T}he tectonic accretions caused a crustal remobilization along major shear zones that has locally contributed to a probable circulation of fluids enriched in ferromagnesian minerals during late {N}eoproterozoic magmatism that created the {BMA} sources.},
