Biogeochemistry: How Our Planet Forms Hydrocarbons Deep Inside
The multi-spheric structure of the Earth forms its skeleton, and the geological molten fluids constitute its blood. Its essence is the cross-spheric migration and redistribution of volatiles (e.g., carbon, hydrogen, […]

Laminae as Structural Biosignatures in NASA’s Life Detection Knowledge Base
Laminae are millimeter-scale features in rocks created by physiochemical processes that can be influenced by the presence and activities of communities of organisms that occur as biofilms and microbial mats.
