Seaward‐Dipping Reflector Influence on Seafloor Magnetostratigraphy—A Pelotas Basin View
Geophysical Research Letters, Volume 49, Issue 23, 16 December 2022., 2022 Abstract Previous works used marine magnetic survey data and interpreted magnetic anomalies related to seaward‐dipping reflectors (SDRs) as oceanic crust or SDR age constraints in the South Atlantic Ocean. However, we advise against using SDR‐related magnetic anomalies to constrain ages because of the mostly low‐dipping geometry causing the overlapping

Obesity Reviews, Volume 22, Issue S5, Octubre 2021., 2021 Resumen Aunque se han hecho avances en el desarrollo y aplicación a gran escala de intervenciones eficaces contra la obesidad infantil, los retos siguen siendo importantes. Nuestro objetivo era comprender las causas del éxito de Estados Unidos y los países latinoamericanos en la implementación de políticas y programas (PYP) contra la obesidad e ...

Provenance of zircon of the lowermost sedimentary cover, Estonia, East-European Craton [PDF]
Bulletin of the Geological Society of Finland, 1999 Bulk and accessory mineral composition of fresh and weathered crystalline rocks, and sedimentary deposits overlying the crystalline-sedimentary unconformity have been examined in core samples from 28 drill holes in Estonia.

The ‘classic stromatolite’ Cryptozoön is a keratose sponge‐microbial consortium
Geobiology, Volume 19, Issue 2, Page 189-198, March 2021., 2021 Abstract Animal evolution transformed microbial mat development. Canonically inferred negative effects include grazing, disturbance and competition for space. In contrast, ancient examples of cooperation between microbial mats and invertebrates have rarely been reported.

Paleomagnetism of Upper Vendian sediments from the Winter Coast, White Sea region, Russia: Implications for the paleogeography of Baltica during Neoproterozoic times [PDF]
, 2002 Paleomagnetic results from an Upper Vendian sedimentary sequence exposed along the White Sea shoreline, NW Russia are described. These classical exposures have been the subject of intense paleontological investigations due to their well-preserved ...
