WebDec 28, 2024 · (2) Caldeira (1995) demonstrated that basalt weathering to CaCO3 cannot respond appreciably to changes in atmospheric and oceanic CO2 because the pH of the interstitial water in contact with the basalt is buffered to a high value, and basalt dissolution is thereby greatly impeded. WebOct 1, 2011 · At pH 2–3 only 6–20% of the divalent metals released from basalt are calcium. At these conditions the divalent metal flux from crystalline basalt dissolution is dominated by Mg and Fe release. The fraction of Ca released increases continuously with rising pH. At pH 11, more than 80% of the divalent metal flux is Ca.
