A synthesis of the LITHOPROBE research has yielded three lithospheric cross-sections, one of which spans the entire continent. Extending down to the base of the North American plate (up to 270 km deep), the cross-sections illuminate the assembly of the North American continent at an unprecedented scale. Posters of the cross-sections are available for download.
LITHOPROBeLITHOPROBE is Canada's major national
research project in the earth sciences. It combines multidisciplinary
earth science studies of the Canadian landmass and surrounding offshore
margins to determine how the northern North American continent has
formed over geological time from 4000 million years ago to the present.
