Solutional landforms (karst) can form on old surfaces on ultramafic rocks in the tropics because of the solubility of some magnesium-rich minerals under warmth and high CO2. The radiocarbon dating of organic pond deposits in several tropical ultramafic karst hollows demonstrates that very slow sediment accumulation has occurred, relative to other tropical shallow lakes. Some sites have gaps in their records, whereas others appear continuous. Sections of organic lake muds from the Indonesian...[Show more]
