The El Bola mafic–ultramafic intrusion (EBMU) appears as a relatively small, sill-like body trending NE–SW, and it dips gently (25–35°) toward the northeast, extending approximately 20 km in length and 1–4 km in width, with a surface area of about 45 km2. EBMU represents the western extension of the El-Baroud Layered Gabbros and the southern extension of the Wadi Abu Hadieda post-collisional gabbroic intrusion and is exposed along Wadi El-Bola, from which it derives its name. The area is structurally complex, intersected by steeply dipping faults trending NE and NW, predominantly exhibiting sinistral displacement, and the area is predominantly composed of the following rocks in a chronological sequence (oldest to youngest):gneisses, metavolcanic rocks, metagabbro–diorite complexes, the mafic–ultramafic intrusion, and finally, younger granite.
