← GeographyWhich chemical consequence results when geothermal vent fluids mix with karst groundwater?
A)Accelerated stalactite and flowstone formation✓
B)Inhibition of calcium carbonate deposition
C)Rapid dissolution of basalt formations
D)Increased silicate mineral crystallization
💡 Explanation
The mixing introduces increased carbonate saturation; therefore, `carbonate precipitation` increases, accelerating stalactite formation, because dissolved carbonates readily precipitate as calcite. This occurs, rather than dissolution dominating, as the vent fluids supersaturate groundwater.
