DOI: 10.1016/j.chemgeo.2019.03.033
Abstract: Abstract Silicate weathering of basaltic rocks constitutes a non-negligible sink of atmospheric CO2 but the role it plays in the regulation of past and future global climate is still matter of debate. In this study,… read more here.

DOI: 10.1016/j.chemgeo.2020.119671
Abstract: Abstract The determination of the mechanisms and extent of soil mineral weathering can be challenging, and the caveats reside in 1) difficulty identifying minerals that are actually involved in weathering reactions, 2) non-stoichiometric release of… read more here.

DOI: 10.1016/j.earscirev.2019.102960
Abstract: Abstract We emphasize the importance of marine silicate weathering (MSiW) reactions in anoxic sediment as fundamental in generating alkalinity and cations needed for carbonate precipitation and preservation along continental margins. We use a model that… read more here.

DOI: 10.1016/j.epsl.2018.04.034
Abstract: Abstract The role of mountains in the geological evolution of the carbon cycle has been intensively debated for the last decades. Mountains are thought to increase the local physical erosion, which in turns promotes silicate… read more here.

DOI: 10.1029/2020pa003909
Abstract: The development of the South Asian monsoon (SAM) and Himalaya‐Tibetan Plateau uplift were closely intertwined with some studies suggesting that uplift initiated the monsoon whereas others link tectonics with monsoon‐controlled exhumation. Silicate weathering controls atmospheric… read more here.

DOI: 10.1111/gcb.16186
Abstract: Climatic and non‐climatic factors affect the chemical weathering of silicate rocks, which in turn affects the CO2 concentration in the atmosphere on a long‐term scale. However, the coupling effects of these factors prevent us from… read more here.

DOI: 10.2475/01.2019.01
Abstract: It has long been recognized that the advent of vascular plants in the Paleozoic must have changed silicate weathering and fundamentally altered the long-term carbon cycle. Carbon cycle models are frequently employed to quantify the… read more here.
