Reply to comments by Sanjay K. Mukhopadhyay, Sucharita Pal, J. P. Shrivastava on the paper by Sial et al. (2016) Mercury enrichments and Hg isotopes in Cretaceous–Paleogene boundary successions: Links to volcanism and palaeoenvironmental impacts. Cretaceous Research 66, 60–81
(Academic Press Ltd - Elsevier Science Ltd, 2017-08)
One key to address the issue of the location of the K/Pg boundary at the Um Sohryngkew sections to look at Ccarb, Corg, Hg/TOC, Mo/Al chemostratigraphies, alongside Hg isotopes, in previous studied K/Pg sections in the ...
Biotic community and landscape changes around the Eocene–Oligocene transition at Shapaja, Peruvian Amazonia: Regional or global drivers?
(Elsevier, 2021)
Since 2012, we have investigated a stratigraphic section encompassing the late Eocene–earliest Oligocene interval at Shapaja (Tarapoto area, Peruvian Amazonia, ca. 7°S), through paleontological and geological fieldwork. ...
Chemostratigraphy and diagenetic constraints on Neoproterozoic carbonate successions from the Sierras Bayas Group, Tandilia System, Argentina
(Elsevier Science, 2007-02)
Carbon and oxygen isotopic data, combined with a detailed diagenetic study, obtained from undeformed and unmetamorphosed dolomite and limestone from the Neoproterozoic Sierras Bayas Group, Argentina, provide a new record ...

Early Jurassic shale chemostratigraphy and U-Pb ages from the Neuquén Basin (Argentina): Implications for the Toarcian Oceanic Anoxic Event
(Elsevier Science, 2010-09)
New data from a Lower Jurassic shale section in the Neuquén Basin, Argentina, are presented in order to better constrain the triggering mechanism for the Toarcian Oceanic Anoxic Event (TOAE) and the associated negative ...
Preglacial palaeoenvironmental evolution of the Ediacaran Loma Negra Formation, far southwestern Gondwana, Argentina
(Elsevier Science, 2018-09)
The Ediacaran Loma Negra Formation may be deposited in a platform environment related to the Clymene Ocean. This unit is exposed in the Olavarría and Barker areas within the Tandilia Basin, and composed entirely of lime ...
