Stock and stabilisation of organic carbon in tephra - buried volcanic soils : a case study in the northern Ecuadorian Andes

Autor: Paque, Mathilde, Ligot, Noa, Morize, Loïc, Onderet, Charline, Delmelle, Pierre, GOLDSCHMIDT 2018

Soils contain at least two times more C than the atmosphere and soil organic carbon (SOC) is involved in rapid exchanges with atmospheric CO2. However, major uncertainties in estimates of C trapped in soils and in the mechanisms that stabilise it may

Seasonal variations of dissolved Ge:Si ratios in streams from the Aso caldera, Kyùshù, Japan

Autor: Gaspard, François, Opfergelt, Sophie, Hartmann Jens, Hosono Takahiro, Delmelle, Pierre, GOLDSCHMIDT 2018

Volcanic island arcs display the highest silicate weathering rates on Earth. In these environments, hydrothermal fluids act as an additional source of acids for weathering reactions. The hydrothermal influence on riverine dissolved weathering fluxes

Volcanogenic acid deposition enhances weathering of Andisols in Nicaragua

Autor: Delmelle, Pierre, Paque, Mathilde, Piessens Lionel, GOLDSCHMIDT 2018

Sulphur and halogen-rich gas emissions from passively degassing volcanoes increase the acidity of the atmosphere and act as a source of acidifying compounds. In these environments, soils, which typically belong to the Andisol order, may be subjected

Soil weathering degree controls silicon bioavailability by increased pH after biochar application

Autor: Li, Zimin, Unzué-Belmonte Dacil, Cornélis Jean-Thomas, Vander Linden, Charles, Struyf Eric, Ronsse Frederik, Delvaux, Bruno, GOLDSCHMIDT 2018

Applying phytolith-rich biochar in agricultural soils increases soil pH, and the contents of plant nutrients and bioavailable silicon (Si). These increase induce positive impacts on plant growth, but hide the ones generated by Si uptake. Here we comp
