Motivations For Study of LIPs
Large igneous provinces (LIPs) are created during short-lived igneous events resulting in relatively rapid and high-volume accumulations of volcanic and intrusive igneous rock. These events warrant study because:
- The study of LIPs has economic implications. Some workers associate them with trapped hydrocarbons. They are associated with economic concentrations of copper–nickel and iron. They are also associated with formation of major mineral provinces including Platinum-Group Element (PGE) Deposits, and in the Silicic LIPs, silver and gold deposits. Titanium and vanadium deposits are also found in association with LIPs.
- Future LIP events may pose a hazard to human civilization. LIPs in the geological record have marked major changes in the hydrosphere and atmosphere, leading to major climate shifts and maybe mass extinctions of species.
- Plate tectonic theory explains topography using interactions between the tectonic plates, as influenced by viscous stresses created by flow within the underlying mantle. Since the mantle is extremely viscous, the mantle flow rate varies in pulses which are reflected in the lithosphere by small amplitude, long wavelength undulations. Understanding how the interaction between mantle flow and lithosphere elevation influences formation of LIPs is important to gaining insights into past mantle dynamics.
- LIPs have played a major role in continental breakup, continental formation, new crustal additions from the upper mantle, and supercontinent cycles.

Famous quotes containing the words motivations, study and/or lips:
“The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.”
—Loris Malaguzzi (1920–1994)
“The study and knowledge of the universe would somehow be lame and defective were no practical results to follow.”
—Marcus Tullius Cicero (106–43 B.C.)
“She sang a song that sounds like life; I mean it was sad. Délira knew no other types of songs. She didn’t sing loud, and the song had no words. It was sung with closed lips and it stayed down in one’s throat.... Life is what taught them, these Negresses, to sing as if they were choking back sobs. It is a song that always ends with a beginning anew because this song is the picture of misery, and tell me, does misery ever end?”
—Jacques Roumain (1907–1945)
