Abstract
Mineral deposition in shallow submarine gasohydrothermal vents may be triggered by microbial activity according to isotopic data obtained for sulphides and carbonates. Submarine gasohydrothermal vents in Punta Mita, at the western coast of Mexico, discharge a mixture of water and gas (mainly nitrogen and methane) at a temperature of 85 °C. Algal mats cover the areas where thermal fluids are being discharged. The main minerals deposited due to the hydrothermal activity are calcite and pyrite. Mo...
