Stratigraphy Flashcards
subdivision of the stratigraphic record into sediments or rocks by means of lithologic
Lithostratigraphy
subdivision of the stratigraphic record into sediments or rocks by means of fossil content
Biostratigraphy
subdivision of the stratigraphic record into bodies of sediment or rock represented by a particular

Lithostratigraphic units are commonly
diachronous
The fundamental biostratigraphic unit
zone
Secular variations, continuous changes of the position of the
magnetic poles, take place over time scales of
10^1 to 10^3 years
Reversals from ‘normal’ polarity to ‘reversed’ polarity occur over
time scales of
10^4 to 10^6 years
The body of strata representing the known stratigraphic and geographic range of occurrence of a particular
taxon or combination of two taxa of any rank.
