Chemical remobilization of contaminant metals within floodplain sediments in an incising river system: implications for dating and chemostratigraphy

open access: yes, 1998
Metals such as Pb, Zn, Cd and Cu from historical mining activity have been used as stratigraphic markers for dating and provenancing vertically accreted, fine-grained floodplain overbank deposits.

Correlation of Bioturbated Facies, Chemostratigraphy, Total Organic Carbon, and Sequence Stratigraphy in the Woodford Shale of South Central Oklahoma [PDF]

open access: yes, 2016
Bioturbation creates a physical change in the primary rock structure and mineralogy. It is evidence of past life in the sediments and can assist in determining the depositional environment.

Carbon isotope chemostratigraphy and petrography of the Yucca Formation, West Texas

open access: yes, 2022
The Yucca Formation is a Lower Cretaceous sedimentary unit found across West Texas. The Cretaceous Period was a time of major global climate change, and the Yucca Formation could record some of those major climatic shifts. However, age constraint must be

Chemostratigraphy (TOC, 13C, 18O) around the Pliensbachian/Toarcian boundary in the reference section of Peniche (Lusitanian Basin, Portugal) [PDF]

open access: yes, 2007
This work presents the chemostratigraphy analysis based on total organic carbon (TOC) and the evolution of the carbon and oxygen stable isotopes in the whole rock samples around the Pliensbachian/Toarcian boundary in the Peniche section (uppermost part

d13Ccarbonate chemostratigraphy of the Carrapateira Outlier (Lower Kimmeridgian), Southern Portugal

open access: yes, 2014
The Carrapateira Outlier (CO) located 20 km north of Sagres is formed by Upper Triassic to Kimmeridgian sediments. The studied section is located at Três Angras bay and consists of approximately 50 m of limestones interbedded with marls, assigned to ...

Albian to Turonian Chemostratigraphy of the Eastern Arabian Plate

open access: yesProceedings, 2010
A chemostratigraphic curve has been established for the Middle Cretaceous Albian to Turonian argillaceous/carbonate sequences of the eastern Arabian Plate. The curve consists of more than 550 δ13C values from outcrop and subsurface data. It is anchored by biostratigraphy and compares favorable with the character of well dated and published curves from ...
