Geology Programme, Abubakar Tafawa Balewa University, PMB 0248, Bauchi, Nigeria aut A study of the gully phenomenon in Gombe Town, Bauchi State: Bedrock geology and environmental implications [Elektronische Daten] [D. Orazulike] In Gombe, Bauchi State, Nigeria, gullies are sculptured in the Upper Cretaceous Pindiga Formation and Gombe Sandstones. The former is a sequence of marine shales with limestone interbeds, the later is a sequence of sandstone, siltstone, and shales. Both formations have ironstone cappings. The degree of gully development, the gravity of attendant soil wastage, and environmental hazards are all related to the rock types in which the gully have formed. Hence, the most grievous situations are posed by gullies in the shale/clay member of the Gombe Sandstone and in the shale/clay/limestone units of the Pindiga Formation. An ‘undercut and collapse' model is put forward to explain gully initiation and propagation in Gombe.
