Rodinia is considered to have formed between 1.3 and 1.23 Ga and broke up again before 750 Ma. [18] Rodinia was surrounded by the superocean Mirovia. According to J.D.A. Piper, Rodinia is one of two models for the configuration and history of the continental crust in the latter part of Precambrian times.
[26] [27] Columbia/Nuna broke up, and the next supercontinent, Rodinia, formed from the accretion and assembly of its fragments. Rodinia lasted from about 1.3 billion years ago until about 750 million years ago, but its configuration and geodynamic history are not nearly as well understood as those of the later supercontinents, Pannotia and ...
The supercontinent Rodinia began to break up 870–845 Ma probably as a consequence of a superplume caused by mantle slab avalanches along the margins of the supercontinent. In a second episode c. 750 Ma the western half of Rodinia started to rift apart: western Kalahari and South China broke away from the western margins of Laurentia ; and by ...
The Mesoproterozoic was the first era of Earth's history for which a fairly definitive geological record survives. Continents existed during the preceding era (the Paleoproterozoic), but little is known about them. The continental masses of the Mesoproterozoic were more or less the same ones that exist today, although their arrangement on the ...
The continent began to break part at a single point but then fractured and ripped open in three different directions. Two of the three rifts that were created were successful and the third failed. The breaking up Rodinia caused the formation of Gondwana or Gondwanaland and Laurentia. [27]

Pulmonary Arterial Hypertension. Pulmonary arterial hypertension (PAH) is a serious condition that happens when the tiny vessels in your lungs narrow, resulting in high blood pressure.
The break-up of Rodinia also resulted in the opening of the long-lived Paleo-Asian Ocean between Baltica and Siberia in the north and Tarim and North China in the south. The closure of this ocean is preserved in the Central Asian Orogenic Belt, the largest orogen on Earth. [36]
