Neoproterozoic

Topics include: global climate change and biotic recovery following the end-Permian mass extinction; evidence of warming during the Neoproterozoic; new insights into structure and dynamics of the San Andreas fault; origin of some of Earth's largest natural crystals; and discovery of Martian rock layers that illuminate the planet's hydrological history.

Babb is currently a freshman in Watershed Sciences at Utah State University, where she is researching paleoclimate indicators and paleocurrents in the Neoproterozoic Era, so I'm working with about 1-billion-year-old rocks, trying to determine what was happening on Earth at that time.

For example, the Neoproterozoic interval, the gap of unknown duration between the time when animals first supposedly evolved and the oldest known fossil or geochemical evidence of animals latest Neoproterozoic, about 600-650 million years ago has not been satisfactorily addressed although Neuweiler and others attempted to.

Topics include: paleoseismology of Yucca Mountain, Nevada; impact of magnetic anomalies in Earth's oceanic crust on plate tectonics; evidence of episodic regional and possibly global glaciation during the Neoproterozoic; insights into Paleocene-Eocene global warming; impact of subduction on Earth's surface characteristics; records of environmental change in Black Coral specimens; and geology's place in the Scientific Revolution.

I care not who makes a country's laws, so long as I can get out an injunction.

The Snowball Earth hypothesis explains the development of glaciation at low latitudes in the Neoproterozoic, as well as the associated iron formations and cap carbonates, in terms of a runaway ice-albedo feedback leading to a global glaciation followed by an extreme greenhouse climate.

Trace fossils that suggest grazing with a radula (Radulichnus) (Erwin & Davidson 2002; Seilacher 1999, 2003), together with large imprints of possible molluscs lacking a mineralized shell (Kimberella) from the latest Neoproterozoic (Erwin & Davidson 2002; Fedonkin & Waggoner 1997; Seilacher 1999, 2003), imply that macroscopic molluscs have a deeper evolutionary history.

Cerrado Verde is a 100% owned project of the Company and is defined by flat lying potash rich metasiltstones belonging to the Serra da Saudade Formation of Neoproterozoic age.

Publishing their findings in the April 30 issue of the journal Science, the researchers also put forth a hypothesis to explain how changes to Earth's surface wrought by the glaciers of the Neoproterozoic Era could have created the anomaly in carbon cycling.
