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 …

Ikaite is a metastable calcium carbonate hexahydrate (CaCO3· 6H2O), which naturally
occurs in environments characterized by temperatures of− 2 to+ 7° C. It is therefore …

Abstract The Iapetus Ocean was the first ancient ocean to be identified following the
development of plate tectonics; its history has been fundamental in relating orogenesis and …

Abstract The Ediacaran Period was an interval of significant global transformation, marked
by major changes in the biosphere, cryosphere, hydrosphere and atmosphere, and possibly …

Combined single zircon crystal CA-ID-TIMS U-Pb dating, micropaleontological study, and
quantitative XRD analysis were used to correlate sections of the Podillya-Moldova …

The deformed margin of the Laurentian craton, preserved within the Appalachian-
Caledonide Orogen, is one of Earth's best studied ancient continental margins. Within the …

Abstract The Great Unconformity erosion surface between Paleozoic sedimentary rocks and
Archean-Proterozoic basement has been related to erosion occurring during Snowball Earth …

Following a decade during which its presence was widely accepted, the existence of the
putative Ediacaran supercontinent Pannotia has come into question since the turn of the …

Here we present a methodology that quantifies fracture arrangement in space as a function
of position (barycenters), size (trace length in 2D), and orientation (variation in strike). We …

Constraining the paleogeography of the Ediacaran is crucial for understanding the extensive
tectonic, biological and geochemical changes that occurred during that epoch …
