Note the white faces on the rock in the right center of the image. This apparently once continuous tube-like lava flow appears to have been pulled apart as this rift formed. Ocular proof of plate tectonics in action. A mini-version of the fit between Africa and South America.

5018 thumbnail picture
A recent lava flow showing white microbial staining on the broken basaltic rocks , caused by discharge of warm hydrothermal fluids through the seafloor. The discharge is still occurring at this location as evidenced by the shimmering aspect of the waters over the white bacterial covered area.

5034 thumbnail picture
Inactive sulfide chimneys along the pinnacle of one tall extinct sulfide spire. It is likely that these once had billows of superheated hydrothermal fluid emanating from them. They form when minerals in the hot fluid precipitate out upon contact with seawater.

An open lava tube. This collapsed feature often occurs when the outer edges of a flow are quickly cooled by contact with seawater. The insulated lava inside remains viscous and eventually recedes, creating a void.
