文摘
- •
A systematic geochemical study of the twins Monticchio maar lakes was performed.
- •
The two lakes are separated by less than 200 m and they exhibit different behaviour.
- •
The “Lago Grande” water are governed by groundwater interactions with host rocks.
- •
The “Lago Piccolo” hypolimnion water are anoxic with a chemical stratification.
- •
The cycling of redox-sensitive elements promotes mineral precipitation with depth.
