Chapter 61 The Neoproterozoic glaciogenic Lillfjället Formation, southern Swedish Caledonides

, 2011
The Tossasfjallet Group, which crops out in the Middle Allochthon of the Scandinavian Caledonides, contains the glaciogenic Lillfjället Fm. Evidence that supports the interpretation of the Lillfjallet formations as glacially related include the presence ...

Reappraisal of the lithological units of the Wuguan Complex: implication for the Paleozoic evolution of the Qinling orogenic belt

Frontiers in Earth Science
The Wuguan Complex, located along the southern margin of the Shangdan suture zone, plays a critical role in investigating the tectonic evolution of the Qinling orogenic belt and constraining the collision timing between the North and South China Blocks ...

Tonian age marker acritarch taxa Hermann from the Mesoproterozoic Chhattisgarh Supergroup, Baradwar sub-basin, central India and its stratigraphic significance

Journal of the Palaeontological Society of India
Compression-preserved acid-resistant organic-walled microfossils (OWM) entombed in fine-grained siliciclastic rocks provide an essential tool for biostratigraphic correlation, especially when alternative methods are scarce.

Evidence of late Neoproterozoic glaciation in the Caledonides of NW Scandinavia

, 2011
The northwestern part of the Scandinavian Caledonides, formed by SE- to ESE-directed thrusting through the Neoproterozoic W. Baltica continental shelf, contains numerous small and often isolated outcrops of diamictite and associated strata.

Neoproterozoic denudation of a Laurentian superbasin

It has long been speculated that isolated Paleoproterozoic basins of northern Laurentia are remnants of a once contiguous sedimentary cover due to similarities in stratigraphy, paleocurrent directions, sediment provenance, and geochronological data. However, corroborating evidence for this 'superbasin hypothesis' has been lacking outside the footprints
