Geological and paleomagnetic data support the hypothesis that a Paleo-Mesoproterozoic
supercontinent, referred to as Columbia, existed before the formation of Rodinia. This pre …

Abstract The Yangtze Block has a Paleoproterozoic and Archean basement and was
traditionally thought to have been cratonized after the Neoproterozoic. Recent studies reveal …

Although A-type granites have long been recognized as a distinct group of granites, the term
A-type was coined first less than thirty years ago. A-type suites occur in geodynamic contexts …

A supercontinent, here named Columbia, may have contained nearly all of the earth's
continental blocks at some time between 1.9 Ga and 1.5 Ga. At that time, eastern India …

The Tarim Craton, located in northwestern China, is one of the largest cratons in China.
Based on the tectonic evolution and stratigraphic sequence, the craton can be subdivided …

A total of 4344 magmatic U-Pb ages in the range 2300 to 800 Ma have been compiled from
the Great Proterozoic Accretionary Orogen along the margin of the Columbia/Nuna …

Prior to participating in Rodinia, the East European Craton (Baltica) had undergone a
complex process of development. Many of the structures, which were important during the …

During the Neoproterozoic, a supercontinent commonly referred to as Rodinia, supposedly
formed at ca. 1100 Ma and broke apart at around 800–700 Ma. However, continental fits (eg …

To this day, there is a great amount of controversy about where, when and how the so-called
supercontinents--Pangea, Godwana, Rodinia, and Columbia--were made and broken …

Between 1.8 and 1.0 Ga (Grenville-age), a series of subparallel accretionary orogens were
added progressively to the southern edge of Laurentia. These belts now extend from …
