Algonkian Group

Algonkian Group

 

or Algonk, nearly unchanged sedimentary layers of the Precambrian period, differentiated as a distinct group of series by the American geologist C. Walcott at the end of the 19th century. Originally, in 1889, the Algonk was said to include layers of deposits which are now attributed to the upper Proterozoic or Riphaeic period (the Grand Canyon and Belt series, USA). Later, in 1899, Walcott also included Huronian sedimentation in the Algonk, thus making it equal in span to the Proterozoic era. “Algonkian group” has become an obsolete term.
