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."
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.
An oceanic or submarine plateau is a large, relatively flat elevation that is higher than the surrounding relief with one or more relatively steep sides. [ 1 ] There are 184 oceanic plateaus in the world, covering an area of 18,486,600 km 2 (7,137,700 sq mi) or about 5.11% of the oceans. [ 2 ]

Colombia is formed by two great territorial zones, one submerged in the Pacific Ocean and the Caribbean Sea covering a total area of 828,660 km 2 and the second is the emerged land which is formed by the Andes mountain range and the Llanos plains that are shared with Venezuela and cover an area of some 1'143,748 km 2.
Picrite from the Duarte Complex in central Hispaniola and the Enriched Basalts in southern Haiti have been inferred as Galapagos hotspot-type island plateau rocks. [ 1 ] The Beloc Formation on the southern peninsula of Haiti preserves tektites , with shocked quartz and plagioclase formed by the asteroid that struck the Yucatán Peninsula and ...
