  <dc:description>Although exposures of Precambrian rocks in the USA are widely scattered, recent studies have provided much information about their subsurface distribution and tectonic history. This article reviews the geological development of the Archean craton, orogenic belts and cratonic cover of Proterozoic age, the Midcontinent rift system, and Precambrian rocks caught up in Phanerozoic terranes. -Author</dc:description>
