Abstract

The morphological kinship of Madagascar to its immediate neighbors on the west (African continent) and east (Indian subcontinent) during the Early and middle Cretaceous has been debated for the past two decades on the basis of available geologic, tectonic, and paleomagnetic information. Most of the paleoreconstructions of Madagascar have shown its attachment to the east African continent. We present magnetic satelite and gravity data, and morphological, geophysical, and geotectonic similarities to hypothesize that in the period before the breakup of Gondwana, Madagascar was a continental fragment of the paleo-super Dharwar craton of India.
