Wikipedia definition
1. Large igneous province​A large igneous province (LIP) is an extremely large accumulation of igneous rocks—intrusive, extrusive, or both—in the earth's crust. In 1992 researchers first used the term large igneous province to describe very large accumulations—areas greater than 100,000 square kilometers (slightly larger than the area of Portugal)—of mafic igneous rocks that were erupted or emplaced at depth within an extremely short geological time interval: a few million years or less.
