Seafloor Chemistry: Life’s building blocks made inorganically

Hydrocarbons in the fluids spewing from a set of hydrothermal vents on the seafloor of the central Atlantic were produced by inorganic chemical reactions within the ocean crust, scientists suggest. The finding holds possibly profound implications for the origins of life.

Small amounts of hydrocarbons emitted from the Lost City hydrothermal vent field (map below shows location) were probably produced by inorganic chemical reactions.
