"Asia" > Geologic history - Tectonic framework. Encyclopædia Britannica. Encyclopædia Britannica Online, 2009: "The paleotectonic evolution of Asia terminated some 50 million years ago as a result of the collision of the Indian subcontinent with Eurasia. Asia’s subsequent neotectonic development has largely disrupted the continent’s preexisting fabric. The first-order neotectonic units of Asia are Stable Asia, the Arabian and Indian cratons, the Alpide plate boundary zone (along which the Arabian and Indian platforms have collided with the Eurasian continental plate), and the island arcs and marginal basins."
