Olivine weathering reaction

WebOlivine forms crystals, which then react with the rest of the parody as pyroxene forms. At a certain point, all olivine is absorbed and found only in pyroxene. The pyroxene then reacts with the liquid and the amphibole crystals replace it and then replace the biotite amphibian. The continuous series is plagioclase feldspar. At high temperatures ... Webcompletely weathered. Olivine needs to react with water and CO 2 to form bicarbonate that capture CO 2 in a solid form. Olivine is still not widely accepted because of environmental uncertainties. Two possible application of olivine enhanced weathering have been found. Olivine can be used mixed as aggregate in the top layer of a road, in the ...

Webbased on accelerating the weathering of rocks. CO 2 reacts with alkaline earth oxide containing minerals to form insoluble car-bonates. Magnesium and calcium silicate deposits, such as ser-pentine and olivine, can be used for this process. Due to the availability and abundance of these minerals, the capacity for mineral carbonation to store CO Webrate of weathering of olivine powder in soil. The second objective was to test how olivine affects plant growth and nutrient uptake. For the semi-natural conditions of a pot experiment, these objectives were achieved by measuring changes in magnesium (Mg) content in soil and crop, and using these to infer olivine weathering.
