Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

The ephemeral nature of most sedimentation processes and the fragmentary character of
the sedimentary record are of first-order importance. Despite a basic uniformity of external …

The classification, tectonic settings, stratigraphy and early diagenesis of carbonate ramp
systems are reviewed. Carbonate ramps are common in all geological periods, but were …

Reefs containing abundant calcified metazoans occur at several stratigraphic levels within
carbonate platforms of the terminal Proterozoic Nama Group, central and southern Namibia …

The unique and evolving nature of the Precambrian geological environment in many ways
was responsible for significant differences between Precambrian clastic sedimentary …

Oxfordian and Berriasian sections representing shallow-water, carbonate-dominated
sedimentary systems have been studied in the Swiss and French Jura, in Spain, and in …

Abstract The Ordovician of Scandinavia (ie Denmark, Norway and Sweden) has been
investigated for over two centuries and, through time, various chronostratigraphic schemes …

Stromatolites are abundant in shallow marine sediments deposited before the evolution of
animals, but in the modern ocean they are restricted to locations where the activity of …

Calcareous skeletons evolved as part of the greater Ediacaran–Cambrian diversification of
marine animals. Skeletons did not become permanent, globally important sources of …

The tectono-depositional evolution of the Yangtze Block during the Ediacaran–Cambrian
transition is controversial, leading to uncertainties in understanding the life-environment co …
