How did Madagascar split from India?
Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is found nowhere else on Earth.
Are Madagascar and India connected?

How did the Itremo sheet form the Madagascar plate?
The Itremo sheet was folded in the amalgamation of Madagascar ~700 Mya, and now contains upright folds, divergent reverse faults, and strike-slip faults. The Madagascar plate experienced two major rifting events during the break-up of Gondwana. First, it separated from Africa about 160 Mya, then from the Seychelles and India 66–90 Mya.
What are the tectonic units that make up Madagascar?
This heavily influenced the geology of central and northern Madagascar. The entire island can be divided into four tectonic and geologic units: the Antongil block, the Antananarivo block, the Bekily Belt in the south, and the Bemarivo Belt in the far north.
Is the Ankaratra Plateau on the East African Rift Zone?
The Aloatra-Ankay rift to the north of the plateau is also seismically active, as well as the Davie Ridge off the coast, which is an extension of the East African Rift Zone. The Ankaratra Plateau contains a major volcanic field with volcanic cones and extensive flows.
