Cryogenian strata of the Windermere Supergroup were deposited in tectonically active
basins throughout the North American Cordillera from Alaska to Mexico. The Windermere …

The supercontinent-cycle hypothesis attributes planetary-scale episodic tectonic events to
an intrinsic self-organizing mode of mantle convection, governed by the buoyancy of …

Abstract The upper Tonian ChUMP (Chuar-Uinta Mountains-Pahrump) strata of the
southwestern USA are hypothesized to be regional correlatives and to record a time of rift …

Neoproterozoic to Cambrian isolation of Laurentia during the breakup of Rodinia was
associated with multiple large igneous provinces, protracted multiphase rifting, and variable …

The reason for the abundance of dolomite lithologies in Earth's early geological record
compared to modern environments remains contentious. This study provides new insight …

Laurentia is the craton that forms the Precambrian core of North America and was a major
continent throughout the majority of the Proterozoic following its amalgamation 1.8 billion …

Abstract The upper Tonian Chuar, Uinta Mountain, and middle Pahrump (ChUMP) groups of
present-day western Laurentia collectively record the early breakup of Rodinia, large-scale …

Paleogeographic models commonly assume that the supercontinent Rodinia was long-lived,
with a static geometry involving Mesoproterozoic links that developed during assembly and …

The temperature and chemistry of early seawater have both been inferred from the isotopic
composition of Precambrian chert (SiO 2), a precipitated mineral formed on or within marine …

The recent revision of the Cryogenian lower boundary from 850 Ma to 720 Ma has nearly
doubled the duration of the Tonian Period to 280 Myrs, an interval longer than the Mesozoic …
