Boundary Layer Control On Mineral Reactivity In Soils And Rocks

It starts when the rain reaches the ground and percolates into the soil, infiltrating the first layers of the Earth’s crust where groundwater circulates. This water reacts with the rocks, dissolving some minerals and growing other ones. In the presence of dissolved carbon dioxide, newly-formed minerals include various carbonate minerals such as calcite, magnesite, or siderite, which form by binding a dissolved carbonate group CO32- with calcium, magnesium, or iron, respectively. These minerals are widespread in the first kilometers of...
