Just over 15 years ago, a proposal forwarded by Rogers and Santosh (2002) posited the
existence of a pre-Rodinia supercontinent which they called Columbia. The conjecture …

Accurate spatial models of tectonic plates and geological terranes are important for
analyzing and interpreting a wide variety of geoscientific data and developing compositional …

Cratons are Earth's ancient continental land masses that remain stable for billions of years.
The mantle roots of cratons are renowned as being long-lived, stable features of Earth's …

Regional groupings of a majority, or all, of Earth's crustal blocks have occurred several times
in Earth history, but only the most recent supercontinent Paleozoic Pangea/Gondwana, is …

Remnants of 2.1–1.8 Ga orogens can be recognized in nearly every craton assembled
within reconstructions of the Rodinia supercontinent, although no particular pattern of …

The Precambrian geologic history of Peninsular India covers nearly 3.0 billion years of time.
India is presently attached to the Eurasian continent although it remains (for now) a separate …

Assembly of the supercontinent Columbia at about 1.85–1.90 Ga coincided with several
events that affected the entire earth. The oldest worldwide network of orogenic belts formed …

Abstract The Proterozoic Eon spans Earth's middle age during which many important
transitions occurred. These transitions include the oxygenation of the atmosphere …

We present possible tectonic models for two crustal domains of the Proterozoic Eastern
Ghats Belt, India based on recent petrological, geophysical and geochronological data …

Abstract The Singhbhum Craton and supracrustal provinces in eastern India are one of a
