Establishing how tectonic plates have moved since deep time is essential for understanding
how Earth's geodynamic system has evolved and operates, thus answering longstanding …

The evolving mosaic of tectonic plates across the surface of the Earth sets boundary
conditions for the evolution of biotic and abiotic processes and helps shape the dynamics of …

The tectonics, geography and climate of the Cretaceous world were very different from the
modern world. At the start of the Cretaceous, the supercontinent of Pangaea had just begun …

The proposal that a Paleo-Mesoproterozoic supercontinent, Columbia, preceded the
existence of Rodinia was forwarded in 2002. A similar proposal that same year provided a …

Abstract The mid-Proterozoic (ca. 1850–850 Ma) is a peculiar period of Earth history in many
respects: ophiolites and passive margins of this age are rare, whereas anorthosite and A …

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

Here we present new 40 Ar/39 Ar geochronology, rock magnetic, and paleomagnetic data
obtained from rocks from three distinct domains of the Precambrian Sveconorwegian orogen …

The initiation of mobile-lid plate tectonics on Earth represented a critical transition towards a
more familiar world in terms of surface temperature stabilization, biogeochemical cycling …

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 …

The amalgamation of Laurentia's Archean provinces ca. 1830 Ma was followed by~ 700 my
of accretionary orogenesis along its active southeastern margin, marked by subduction of …
