Geophysical Insights Into 3D Crustal Architecture of Jurassic Magmatic Intrusions in the Moroccan Atlas

Magmatic intrusions in rifted continental margins play a critical role in shaping structural evolution, yet their geometry and emplacement mechanisms remain poorly constrained in salt‐influenced terrains. The Moroccan Central High Atlas, a segment of the Atlas fold‐and‐thrust belt, hosts extensive Middle Jurassic to Early Cretaceous intrusions that interact intricately with pre‐existing rift structures and evaporite‐rich stratigraphy. Yet, their deep subsurface architecture remains poorly resolved due to limited high‐resolution imaging. Here, we integrate legacy aeromagnetic and gravity data with modern 2D forward modelling and 3D inversion to resolve the spatial distribution, depth extent, and structural controls of magmatic bodies beneath the Central High Atlas. Our results reveal steeply dipping, dyke‐like intrusions aligned with ENE–WSW‐trending inherited faults, indicating tectonic inheritance strongly influenced magmatic plumbing. We demonstrate that ascending magmas exploited pre‐existing tectonic fabrics, driving salt mobilization and contributing to the growth of diapiric structures. These findings provide the first crustal‐scale geophysical image of subsurface intrusions in this region, establishing a genetic link between salt tectonics, magma emplacement, and structural inheritance. Importantly, this is the first 3D crustal‐scale geophysical reconstruction of Jurassic magmatic plumbing in the Atlas, revealing their role in diapirism and regional uplift.
