2021-03-02. The onset of Asian dust

The retreat of the proto-Paratethys Sea resulted in aridification and the onset of a high-pressure system over Siberia driving the East Asian winter monsoon and dust storms.

Enjoy Niel’s cutting edge thesis work including the age of the onset of Asian dust production, a new hypothesis for this dust generation and a reappraisal of grain size methods for dust interpretations. See also Niel’s great review on interpreting dust in the sedimentary record.

2021-02-10. Global reconstructions on interactive website

The accomplishment of years of work for Fernando’s masterpiece (monsterpiece?). It includes revisions of the geologic literature over the main orogens and a new approach to making paleoreconstructions with an associated interactive website including database and updates. Check it out!

The topographic evolution of the Tibetan Plateau is essential for understanding its construction and its influences on climate, environment, and biodiversity. The timing of uplift is a hugely controversial topic that is resolved in our recent paper:

Amazing and surprising results from Jan’s thesis constrain the position of Burma to very low latitudes showing it was not part of Asia with huge implication on the India-Asia collision as well as on Asian biodiversity evolution.
