Juxtaposition of India and Antarctica During the Precambrian: Inferences from Geochemistry of Mafic Dykes. April ; Gondwana Research 3(2); DOI: /SX(05)X. Precambrian, period of time extending from about billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, million years Precambrian encompasses the Archean and Proterozoic eons, which are formal geologic intervals that lasted from 4 billion to about million years ago, and the Hadean Eon, which is an informal interval spanning from.
The East Antarctic Craton is an ancient craton that forms most of East Antarctic Craton was part of the supercontinent Nena billion years ago.
During the early Paleozoic Era East Antarctica joined Gondwana. Breakup. During the Mesozoic breakup of Gondwanaland, East Antarctica separated from other major continental areas.
During and following this breakup the. The closing of this ocean basin during the Eastern Ghats–Rayner orogeny at ~ Ma was related to the amalgamation of India and East Antarctica to form the supercontinent Rodinia. During the Neoproterozoic, this part of Rodinia was involved in orogenic collapse/extension and deposition of the Sodruzhesvo Group.
Rodinia: – Ma. East Antarctica comprises Archean and Proterozoic-Cambrian terranes that amalgamated during Precambrian and Cambrian times. In the time of the supercontinent Rodinia, western Australia and East Antarctica were linked by the two-stage Albany-Fraser-Wilkes orogen, which occurred between Ma and Ma, and also the older, Mawson craton.
The Dharwar Craton, one of the parts of the Indian shield, is estimated to be 3 billion years old -- one of the oldest continental fragments in the world. This book surveys the Precambrian geology of peninsular India and, to some extent, the Himalayas.
The authors discuss the similarities and differences between the crustal blocks of the shield and incorporate details concerning geochemistry. India and Antarctica during the precambrian and granulite and crustal processes in East Gondwana Divi, R.

A 3-station triangulation experiment and simultaneous magnetic recording (digital and/or analog) were carried out with a view to understanding the dynamics of the auroral current systems.; Atmospheric electrical parameters near the Kamat Hut at Maitri were measured to study the global electric circuit.
Sudipta Sengupta is a professor in structural geology in Jadavpur University, Calcutta, India, and a trained is one of the first Indian women (along with Aditi Pant) to set foot on Antarctica.

Major time divisions in the history of the Earth. Paleogeographic reconstructions suggest that India and Antarctica were closely positioned at equatorial latitudes in the Early Neoproterozoic (– Ga) and in the Late Neoproterozoic/Early Paleozoic, and Ga (Torsvik, ; Li et al., ).In the intervening period, broadly overlapping with the dispersal of crustal fragments of the Rodinia supercontinent, the Greater India.
Reconstruction of Gondwanaland during the Precambrian time is based on several geological, geophysical and geochemical evidences. Juxtaposition of India and Antarctica. Fracture‐lineament systems of Sri Lanka and Antarctica formed after the latest Silurian and during or before the Jurassic conform in this reconstruction.
An improved fit of the m isobaths of India‐Sri Lanka‐Antarctica and continuation of the latest Archaean mobile belt from Enderby Land to peninsular India is obtained by fitting Sri.
Precambrian rocks constitute most of the Indian peninsula, and occur in the Himalayas and related mountainous regions along the northern part of the country.

This book provides a general description of the major features of the Indian Shield, dividing its discussion by geologic and geographic s: 1. During the early Paleozoic era, South America, Africa, Australia, Antarctica, India, and perhaps China comprised the vast southern continent of _____.
A) Europe B) Laurasia C) Gondwanaland D) Antindia E). Special Publication The Proterozoic aeon involved at least three major continental readjustments. India and Antarctica appear in most models of supercontinent reconstructions, but their relative position has been the subject of debate.
High-resolution petrological and geochronological data, especially from the Proterozoic mobile belts, provide the principal means of resolving this issue.

This book presents findings from research into the Precambrian history of the Indian shield obtained using state-of-the-art technology.
It demonstrates a paradigm shift towards studying the Precambrian shield regions using petrological, geochemical, structural, metallogenic, sedimentological and paleobiological data from the rocks in the Precambrian shield area, and presents a collection of.
