Stratigraphy of the Anthropocene

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
The Anthropocene, an informal term used to signal the impact of collective human activity on biological, physical and chemical processes on the Earth system, is assessed using stratigraphic criteria. It is complex in time, space and process, and may be considered in terms of the scale, relative timing, duration and novelty of its various phenomena. The

The stratigraphy of Mars [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 1986
A detailed planetwide stratigraphy for Mars has been developed from global mapping based on Viking images and crater counting of geologic units. The original Noachian, Hesperian, and Amazonian Systems are divided into eight series corresponding to stratigraphic referents.

Dynamic Stratigraphy: An Introduction to Sedimentation and Stratigraphy

open access: yesEos, Transactions American Geophysical Union, 1985
This text is an expanded and updated edition of the original 1974 volume. The prose is aimed at an undergraduate readership and is clear and concise. The subtitle of the book, however, gives a better idea of its contents than does the main title, as a significant proportion of the text is devoted to the development and description of sedimentation ...

2. Stratigraphie

open access: yes, 1989
La stratigraphie a mis en évidence des couches associées à l’occupation du site et des dépôts liés à des remblaiements essentiellement naturels.Les séries d’occupation paraissent cycliques. Un niveau de préparation est soigneusement aménagé. Il supporte un lit de matériaux organiques (cendres) qui forme le niveau d’occupation, riche en mobilier ...

Cladistics and Stratigraphy

open access: yesGeosciences, 2023
Using cladistic phylogenies (cladograms) to evaluate stratigraphy (taxon distributions and correlations) necessitates various assumptions that include all of the assumptions built into the cladogram, assuming the cladogram is “correct” and that new taxa only arise by dichotomous splitting.
