Abstract

It has been found experimentally that the intensity of the leaching under the interaction of volcanic ash and seawater decreases as Ca > Mg > Si, and the mobilization of calcium and magnesium is more intense compared to silicon by factors of 30–70 and 20–50, respectively. Calcium and magnesium supplied to seawater owing to the halmyrolysis of the terrigenous pyroclastic matter may then interact with the products of organic matter oxidation to fix the free carbon dioxide in the form of autochthonous carbonates. It was shown that the halmyrolysis of terrigenous pyroclastic matter could not provide the complete immobilization of the autochthonous CO2 produced in the ocean by the oxidation of organic matter. Thus, some other sources exist for the reactive silicates of calcium and magnesium, and these might probably be the silicates of the continental runoff of solid substances.
