Introduction to the thematic collection ‘Mesozoic and Cenozoic tectonics, landscape and climate change in and around the Tibetan Plateau and SE Asia’

As the largest active convergent orogenic system, the Himalaya–Tibetan Plateau and SE Asia stand out as globally significant tectonomorphic features. Mesozoic and Cenozoic tectonic convergence among the Eurasian, Australian–Indian and Pacific plates, involving oceanic subduction, arc accretion, and continental collision has not only formed the world's highest Himalaya–Tibetan Plateau and geometrically diverse volcanic arcs in east and SE Asia, but also reactivated ancient orogens in central Asia. These tectonically diverse regions also host complex topography, environment, and climate systems, including the Asian monsoon, which impacts about half of the global population. Publications in this thematic issue present the latest multidisciplinary advances in Mesozoic and Cenozoic tectonics, landscape evolution, palaeoclimate records and geohazards, and their interactions in and around the Tibetan Plateau and SE Asia.
