A Central African Shield Amalgamation Tale

Date Time
A Central African Shield Amalgamation Tale
The Earth has a 4.6-billion-year history; since about 1.9 billion years ago, it has been punctuated by a quasi-cyclic formation and break up of supercontinents – large landmasses that comprised the majority of the Earth’s continental crust. The formation and disruption of supercontinents had great impact on the environment, climate and possibly Earth’s interior.
Reconstructing the processes of amalgamation and disruption of these supercontinents is crucial to our understanding of plate tectonics, plate motion, thermal balance of the Earth, and long-term environmental changes.
There is a large consensus that around 200 million years from now the Earth will form another supercontinent, possibly centered in present day Asia. ....

Abstract
A 4.9 Mkm
2 region of the southwest Pacific Ocean is made up of continental crust. The region has elevated bathymetry relative to surrounding oceanic crust, diverse and silica-rich rocks, and relatively thick and low-velocity crustal structure. Its isolation from Australia and large area support its definition as a continent Zealandia. Zealandia was formerly part of Gondwana. Today it is 94% submerged, mainly as a result of widespread Late Cretaceous crustal thinning preceding supercontinent breakup and consequent isostatic balance. The identification of Zealandia as a geological cont ....

The age of fossil rock is determined using isotopes.
Bhimbetka, the famed Central Indian cave art repository near Bhopal dating back to Palaeolithic and Mesolithic times, has yielded a fossil find dating back about 550 million years, the first time the particular fossilised organism has been recorded in India. It dates back to an era regarded as the precursor to the explosion of life on earth during the Cambrian period and puts India firmly on the map for studies of the Ediacaran era along with Australia and Russia. Here’s what ....

Discovery near Bhopal is of the earliest known animal about 550 million years old
Researchers have discovered three fossils of the earliest known living animal the 550-million-year-old ‘Dickinsonia’ on the roof of the Bhimbetka Rock Shelters, about 40 km from Bhopal.
One can identify the fossils from the white leaf-like patches with a central vertebra (central midrib) and connecting veins. While one fossil is 17 inches long, the other two are much smaller. ....

Bhopal, Feb 10: Eleven feet up on the wall of an area called Auditorium Cave at Bhimbetka Rock Shelter near Bhopal, a group of geologists on a cultural visit has spotted a pattern that looks like an imprint of Dickinsonia.
Bhimbetka Rock Shelters, a UNESCO World Heritage Site for Paleolithic and Mesolithic cave art, near Bhopal is located in the capital of the central state of Madhya Pradesh.
Dickinsonia is a well-known fossil dating back 550 million years to the initial years of complex life on Earth. ....
