Plate tectonic reconstruction of India and Madagascar closing through the Mascarene Basin
Abstract
The western continental margin of India was formed due to the rifting and drifting among India, Madagascar and Seychelles. Several researchers provided relative configuration of India and Madagascar in their pre-break-up stage, but those models differ from each other. One of the main reasons for such a discrepancy is the absence of detailed magnetic anomaly identification from the Mascarene Basin, which is the region formed by the seafloor spreading between India and Madagascar. Based on the recently published detailed magnetic anomaly identifications in the Mascarene Basin, an attempt is made to reconstruct India-Madagascar pre-break-up juxtaposition by directly closing the Mascarene Basin, instead of closing through the Indian-Antarctica-African circuit.
