Layered intrusions in East Greenland, mostly close to the contact between PreCambrian gneisses and Tertiary flood basalts, are commonly several million years younger than the flood basalts.
Lamont scientists utilize a variety of observational and computational techniques to image and model the deep interior of the Earth, from crust to core.
Continental margins are the Earth's principal loci for producing hydrocarbon and metal resources, for earthquake, landslide, volcanic and climatic hazards, and for

Earth has limits to the amount of carbon dioxide in its atmosphere before the environment as we know it starts to change. Too much CO2 absorbed by the oceans makes the water more acidic. Too much in the atmosphere warms the planet. With emissions from our carbon-based economies rising, scientists at Columbia University’s Lamont-Doherty Earth Observatory are developing way to prevent CO2 produced by power plants and industries from ever entering the atmosphere, and they are exploring ways to take CO2 out of the environment.
The raw materials of some volcanic islands are shaped by some of the same processes that form diamonds deep under the continents, according to a new study. The study asserts that material from diamond-forming regions journeys nearly to earth’s core and back up to form such islands, a process that could take two and a half billion years or longer – more than half of earth’s entire history. The research challenges some prevailing notions about the workings of the deep earth, and their connections to the surface.
