Trace metals and nutrients in tropical volcanic island rivers: Insights on chemical weathering and anthropogenic influences of Pohnpei, Micronesia
Han Su,Shan Jiang,Xiaodao Wei,Jie Jin,Yan Chang,Shuo Jiang,Xing Xiang Shi,Zhengyang Liu,Jing Quan Zhang +8 more
TL;DR: In this article , the authors conducted field surveys in a Pacific volcanic island, Pohnpei, Micronesia, and determined the substance composition of river waters (major ions, trace metals, nutrients, etc.) to quantify terrestrial material loading and biogeochemical influence on the surrounding oceans.

Opportunity for Increasing the Soil Quality of Non-arable and Depleted Soils in South Africa: a Review
TL;DR: In this paper , the authors determine the utility of augmentation with rock dust in terms of benefits to soil properties during the weathering of primary minerals, and include a background on the current situation in South Africa regarding soil and climatic conditions and how the usage of rock dust can improve the situation at hand.

Water budget of tropical volcanic lakes in center‐north Cameroon: Reconciling the stable isotope and chloride mass balance
TL;DR: In this paper , the authors present a hydrological and geochemical investigation of five of these lakes (Mbalang, Tabere, Tizon, Gegouba and Baledjam) around Ngaoundere on the Adamawa Plateau, based on repeated sampling of water profiles and monthly monitoring of rain and lake water samples over two seasonal cycles.

Global silicate weathering and CO2 consumption rates deduced from the chemistry of large rivers
TL;DR: In this article, newly compiled data on the 60 largest rivers of the world are used to calculate the contribution of main lithologies, rain and atmosphere to river dissolved loads, and the relationship between the chemical weathering rates of silicates and the possible controlling parameters are explored.

The carbonate-silicate geochemical cycle and its effect on atmospheric carbon dioxide over the past 100 million years
TL;DR: In this article, a computer model has been constructed that considers the effects on the CO/sub 2/ level of the atmosphere, and the Ca, Mg, and HCO/sub 3/ levels of the ocean, of the following processes: weathering on the continents of calcite, dolomite, and calcium-and-magnesium-containing silicates; biogenic precipitation and removal of CaCO 3/from the ocean; removal of Mg from the ocean via volcanic-seawater reaction; and the metamorphic-magmatic decarbon

Tectonic forcing of late Cenozoic climate
TL;DR: In particular, tectonically driven increases in chemical weathering may have resulted in a decrease of atmospheric C02 concentration over the past 40 Myr as discussed by the authors. But this was not shown to be the case for the uplift of the Tibetan plateau and positive feedbacks initiated by this event.

Geocarb III: A Revised Model of Atmospheric CO2 over Phanerozoic Time
TL;DR: In this article, the GEOCARB model has been updated with an emphasis on factors affecting CO2 uptake by continental weathering, including the role of plants in chemical weathering and the application of GCMs to study the long-term carbon cycle.

A negative feedback mechanism for the long‐term stabilization of Earth's surface temperature
TL;DR: In this article, it is suggested that the partial pressure of carbon dioxide in the atmosphere is buffered, over geological time scales, by a negative feedback mechanism, in which the rate of weathering of silicate minerals (followed by deposition of carbonate minerals) depends on surface temperature, which in turn depends on the carbon dioxide partial pressure through the greenhouse effect.
