A conodont-based Silurian chronostratigraphy
Geological Society of America Bulletin, 1989Ranges of 79 conodont species are used to effect a graphic correlation of upper Llandoverian-Pridolian (Silurian) rocks in 30 stratigraphic sections in Europe and North America. A Silurian Composite Standard Section (CSS) developed by this method provides the total stratigraphic ranges for all species for which there is information in the system. These

Chronostratigraphy of upper Eocene microspherules
PALAIOS, 1989Impact-glass microspherules occur at numerous localities in rocks that can be dated as late Eocene. There is debate as to whether the discovered microspherule layers are the result of two or three impact events. Standard biostratigraphic techniques have been employed to date the microspherule layers.

Chronostratigraphie de l'Europe würmienne
Bulletin de l'Association française pour l'étude du quaternaire, 1968From recent data, the author strives to justify division of the Würm in three parts: Eowürm (75 000 B P. -55 000 B P.), Mesowürm (55 000 B. P. -27 000 B.P.), , Néowürm (27 000 B.P.-10 300 B P.). He tries to caracteris some great natural domains utilizing particularly mousterian and leptolithic settlements maps, « front pioneer » succeeding positions ...
