The Caribbean large igneous province (CLIP) consists of a major flood basalt, which created this large igneous province (LIP). It is the source of the current large eastern Pacific oceanic plateau , of which the Caribbean-Colombian oceanic plateau is the tectonized remnant.

In 1992, Coffin and Eldholm initially defined the term "large igneous province" as representing a variety of mafic igneous provinces with areal extent greater than 100,000 km 2 that represented "massive crustal emplacements of predominantly mafic (magnesium- and iron-rich) extrusive and intrusive rock, and originated via processes other than 'normal' seafloor spreading."
Island-like outcrops of metamorphic rocks in the eastern Llanos are visible remnants of Precambrian times. During the 289-million-year-long Paleozoic Era, which began 539 million years ago, the ocean invaded the area which is exposed in Colombia's Andean zone, as subterranean volcanic eruptions in the western part of the country spouted lava.

Jetties are rock structures that provide a protected passage into and out of the ocean. Designed to reduce the waves coming into an inlet, jetties stick out into the ocean, like boardwalks.
The Caribbean plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the northern coast of South America. Roughly 3.2 million square kilometres (1.2 million square miles) in area, the Caribbean plate borders the North American plate, the South American plate, the Nazca plate and the Cocos plate.
Oceanographers explored an area around the Pacific Ocean’s Nazca Ridge and found a massive underwater mountain. Using a sonar system, the researchers digitally mapped the seafloor of the area ...
The Caribbean Sea. Most of the Caribbean countries are islands in the Caribbean Sea, with only a few in inland lakes. The largest islands include Cuba, Hispaniola, Jamaica and Puerto Rico. Some of the smaller islands are referred to as a rock or reef. Islands are listed in alphabetical order by sovereign state.
