Cataclastic deformation bands affecting alkaline volcaniclastics along an emerged island in oceanic fracture zone: the Paredão Volcano, Trindade Island Open
The presence of deformation bands (DBs) associated with porous volcaniclastic rocks, it is ubiquitous but poorly described. In Trindade Island, the Paredão Volcano's lapilli tuffs are deposited during the Middle Pleistocene, and several de…
