Dissected plateau this plateau are known as mesas, and long, connected portions are known as potreros. Dissected plateau A dissected plateau is a plateau area that has been severely eroded so that the relief is sharp. Such an area may be referred to as mountainous, but dissected plateaus are distinguishable from orogenic mountain belts by the lack of folding, metamorphism, extensive faulting, or magmatic activity that accompanies orogeny. The Allegheny Plateau, the Cumberland Plateau, the Ozark Plateau, and the Catskill Mountains in the United States and the Blue Mountains in Australia and the Deccan Plateau in India are examples of dissected plateaus
Mackenzie Large Igneous Province on Earth. Igneous rocks of the Mackenzie Large Igneous Province are generally mafic in composition, including basalt and gabbro. Even though the Mackenzie Large Igneous Province is classified as a large igneous province like other extremely large accumulations of igneous rocks on Earth, it is much larger than large igneous province standards. The standard size classification for large igneous provinces is a minimum areal extent of . However, the Mackenzie dike swarm itself occupies an area of at least , making the Mackenzie Large Igneous Province larger than the Ontong Java Plateau (in the southwestern Pacific Ocean) and the U.S.
