TS Must-Read – Yin and Harrison (2000) Geologic evolution of the Himalaya-Tibetan Orogen

Yin and Harrison (2000) puts together an exhaustive review of three decades of geological and geophysical investigations on the Himalayan-Tibetan orogen. This research supports the orogenesis started during the Cenozoic between 70 and 50 Ma ago as a consequence of the Indo-Asian collision following the closure of the Tethys ocean between Laurasia and Gondwana. Yin and Harrison (2000) underlines th ...[Read More]

TS Must-Read – Armijo et al. (1986) Quaternary extension in southern Tibet: field observations and tectonic implications

This contribution is a very detailed field report of the Sino-French expedition in eastern Tibet that took place in 1980-1982. Armijo and coauthors accurately analyse the different tectonic styles present in the north and south of the Yarlung-Zangbo Suture Zone, frequently defined as the “chord” joining the eastern and western syntaxes of the Himalayan orogen (Fig. 1). North of the chord, strike-s ...[Read More]

This edition of Minds over Methods article is written by Sarah Kachovich and discusses how tiny fossils can be used to address large scale tectonic questions. During her PhD at the University of Brisbane, Australia, she used radiolarian biostratigraphy to provide temporal constraints on the tectonic evolution of the Himalayan region – onshore and offshore on board IODP Expedition 362. Sarah  ...[Read More]
