Those formed by tectonic events, such as folding or faulting of rock units, are called structural traps. The most common structural traps are anticlines, upfolds of strata that appear as inverted V-shaped regions on the horizontal planes of geologic maps. About 80 percent of the world''s petroleum has been found in anticlinal traps.
