The carbonic acid-rock reaction in feldspar/dolomite-rich …
· When feldspar with silicate ions reacted with water and CO 2, kaolinite precipitation and silicic acid were formed. The content of dolomite was reduced from 7.7% to 6.6% after dissolution. In an acidic environment, dolomite and carbonic acid underwent a dissolution reaction and produces Ca 2+, Mg 2+, and HCO 3 − to form soluble carbonate. And ...
