Autor: Germain Bayon, Martin Patriat, Yves Godderis, Anne Trinquier, Patrick De Deckker, Denise K. Kulhanek, Ann Holbourn, Yair Rosenthal
Publikováno v: Science Advances (2375-2548) (American Association for the Advancement of Science), 2023-03, Vol. 9, N. 13, P. eadf3141 (10p.)
Arc-continent collision in Southeast Asia during the Neogene may have driven global cooling through chemical weathering of freshly exposed ophiolites resulting in atmospheric CO 2 removal. Yet, little is known about the cause-and-effect relationships
