Shield (geography)
From Biocrawler, the free encyclopedia.
In geography, a shield is a large Archaean (Precambrian) rock mass at the centre of a continent, such as the Canadian Shield, Baltic Shield, and the Arabian-Nubian Shield. The term, in this sense, was translated from German schild by H. B. C. Sollas in Suess's Face of Earth in 1901.
