Effects of mineralogy, chemistry and physical properties of basalts on carbon capture potential and plant-nutrient element release via enhanced weathering

Amy L.Lewis, Binoy Sarkar, Peter Wadea, Simon J.Kemp, Mark E.Hodson, Lyla L.Taylor, Kok Loong Yeong, Kalu Davies, Paul N.Nelson, Michael I.Bird, Ilsa B.Kantola, Michael D.Masters, Evan DeLucia, Jonathan R.Leake, Steven A.Banwart, David J.Beerling Abstract Mafic igneous rocks, such as basalt, are composed of abundant calcium- and magnesium-rich silicate minerals widely proposed to be suitable for scalable carbon dioxide removal (CDR) by enhanced rock weathering (ERW). Here, we report a detailed characterization of the mineralogy, chemistry, particle size and surface area of six mined basalts being used in large-scale ERW field trials. We use 1-D ...
