Talk Abstract:
Greater India is part of the Indian plate that was subducted under Asia. Knowing the original surface area of Greater India is a key parameter to define the kinematics of the India-Asia collision, arguably one of the most important tectonic events to shape our planet in the Cenozoic. However, several decades of research have led to gaping discrepancies concerning both the size of the Indian plate in a Gondwanaland configuration and the tectonic history of India, which includes its collision with Asia and the subsequent creation of the Tibetan Plateau. Paleomagnetism and the underlying origin of the magnetic carriers (rock magnetism) lie at the heart of the controversy. Our presentation will introduce the Greater India problem and highlight approaches to solving this paleomagnetic puzzle.
