Comparative diagenesis at three site on the Canadian continental margin
(Journal of Marine Research, 1998)
Diagenesis of carbon, oxygen, nitrogen, and manganese at three sites on the Canadian continental margin is quantitatively compared and contrasted using results from a computer code (CANDI) published by Boudreau (1996a).The ...
Carbonate REE plus Y signatures from the restricted early marine phase of South Atlantic Ocean (late Aptian - Albian): The influence of early anoxic diagenesis on shale-normalized REE plus Y patterns of ancient carbonate rocks
(Elsevier B.V., 2018-07-01)
Rare earth elements plus yttrium have been extensively applied in paleoenvironmental studies of ancient carbonate successions due to their fractionation in the marine environment. However, in modem marine anoxic environments, ...

Diagenesis of the Vaca Muerta Formation, Neuquén Basin: Evidence from petrography, microthermometry and geochemistry
(Elsevier, 2021-02)
The Tithonian Vaca Muerta Formation (500 m-thick marine carbonates) in the Pampa de Tril area is a potential unconventional hydrocarbon reservoir but earlier studies rarely focused on its diagenetic history. It constitutes ...
Chemometric study of the preservation modes of Athabaskia anax (Trilobita, Cambrian Precordillera, Mendoza, Argentina): Implications for taxonomy
(Elsevier, 2021-08)
Selected pygidia of the middle Cambrian corynexochid trilobite Athabaskia anax (Walcott 1916) from the Miaolingian Series of San Isidro (Precordillera, Mendoza, Argentina) are analyzed for the first time using scanning ...

Macroscopic and microbiological alterations of bird and small mammal bones buried in a Cerrado biome (south western Brazil)
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTDLONDON, 2012)
In this paper, we present the results of an experimental approach developed to study the macroscopic and microbiological alteration of bird and small mammal bones buried under a Cerrado biome. The first experiment evaluated ...
