Laurentian craton

Target entity: Laurentian craton
Context triple: [Grenville orogenic belt, partOf, Laurentian craton]

• A. Nain craton
  The Nain craton is an ancient, stable block of Earth’s continental crust in northeastern Canada, composed largely of Archean rocks and forming part of the geological core of North America.
• B. North Atlantic Craton
  The North Atlantic Craton is an ancient, stable block of Earth’s continental crust in the North Atlantic region, composed largely of Archean and early Proterozoic rocks that record some of the planet’s earliest geological history.
• C. Superior craton
  The Superior craton is one of Earth’s largest and oldest stable continental cores, forming much of the ancient geological foundation of central and eastern Canada and parts of the northern United States.
• D. Greenland Shield
  The Greenland Shield is an ancient Precambrian geological core of Greenland composed mainly of highly metamorphosed crystalline rocks that form part of the larger North American craton.
• E. Rae craton
  Rae craton is an ancient, stable block of Earth’s continental crust that forms a major geological core of the Canadian Shield within the North American craton.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
