WebThe finely divided, red, brown, and yellow soil-coloring minerals originate by what process? chemical weathering of quartz and feldspars. mechanical weathering of very fine-grained, blue-gray clays. mechanical weathering of the feldspars and micas in granite and rhyolite. precipitation of iron oxides during the chemical weathering process. WebApr 8, 2024 · 1.Introduction. Silicate weathering is a major control on Earth's atmospheric CO 2 concentrations (e.g., Berner, 2004).When silicate minerals weather, they draw CO 2 out of the atmosphere, producing alkalinity, cations, and aqueous SiO 2 (Eq. (1)).Some of the dissolved inorganic carbon is precipitated as calcium carbonate in the ocean and …
