Eocambrian

Eocambrian

[‚ē·ō′kam·brē·ən]
(geology)
Pertaining to the thick sequences of strata conformably underlying Lower Cambrian fossils. Also known as Infracambrian.

Eocambrian

 

beds of the Upper Precambrian that immediately preceded the Cambrian system (seePRECAMBRIAN). The term “Eocambrian” was introduced by the Norwegian geologist W. C. Brøgger in 1900 and was applied to the sparagmite series (seeSPARAGMITE SERIES). It became widely used in the Western European countries. The concept of the Eocambrian is not used in the USSR; the corresponding beds are called Wendian (seeWEND COMPLEX).
