Importance of lepidolite in geological carbon cycles

Lepidolite, a lithium-rich mica mineral, plays a significant role in geological carbon cycles, particularly in the context of long-term carbon sequestration and climate regulation. This mineral's importance stems from its unique chemical composition and its involvement in various geological processes that influence carbon dioxide levels in the atmosphere and oceans.

The carbon cycle in lepidolite-rich environments begins with the weathering of lepidolite-bearing rocks. As these rocks are exposed to atmospheric conditions and water, chemical reactions occur, leading to the breakdown of lepidolite and the release of lithium ions. This process consumes carbon dioxide from the atmosphere, as carbonic acid formed from atmospheric CO2 and water reacts with the mineral surface.

The released lithium ions then enter aqueous systems, such as rivers and groundwater, where they can influence carbonate precipitation. Lithium has been shown to enhance the formation of carbonate minerals, particularly in marine environments. This process effectively locks atmospheric carbon into stable mineral forms, contributing to long-term carbon sequestration.

Furthermore, lepidolite's role extends to its influence on biological carbon fixation. Lithium, released from lepidolite weathering, can stimulate primary productivity in marine ecosystems. This increased biological activity leads to enhanced carbon uptake by phytoplankton and other marine organisms, ultimately resulting in the burial of organic carbon in marine sediments.

In terrestrial ecosystems, the weathering of lepidolite-rich rocks can lead to the formation of lithium-rich soils. These soils may influence plant growth and carbon sequestration rates in vegetation, although this aspect requires further research to fully understand its implications for the global carbon cycle.

The importance of lepidolite in geological carbon cycles is also evident in its potential to influence the carbon dioxide content of magmas. During partial melting of the Earth's crust, lepidolite-bearing rocks can contribute to the formation of lithium-rich magmas. These magmas may have different carbon solubilities compared to typical magmas, potentially affecting the outgassing of CO2 during volcanic eruptions and thus impacting atmospheric carbon levels over geological timescales.

Additionally, the presence of lepidolite in certain geological formations can affect the storage capacity of carbon in sedimentary basins. Lithium-rich pore fluids derived from lepidolite weathering can influence the diagenesis of carbonate sediments, potentially enhancing or inhibiting the preservation of carbonate minerals and, consequently, the long-term storage of carbon in these geological reservoirs.
