Tectonic Evolution And Preservation Of Relict Structures In A Triangle Zone: The Tácata Triangle Zone (Maturín Basin, Eastern Venezuela)

The Tácata structure in Eastern Venezuela is a vertical stack of south- and north-verging thrust sheets<br>within a triangle zone. The Tácata trend evolved as an interplay of regional plate-driven compression and<br>critical-taper driven thrusting. As a result, it records the relatively stationary deformation front of the Serranía del<br>Interior fold-and-thrust belt in this area from the Early Miocene to present day. This led to the preservation of<br>relict triangle zone structures, a unique feature in thrust belt deformation fronts, where relict structures are<br>commonly exhumed and eroded.
