Abstract
⺠Sulfur geochemistry documents effects of the subsurface biosphere in lower ocean crustal gabbros altered at low temperatures. ⺠The gabbros gain sulfur and have elevated sulfur isotope ratios. ⺠Sulfur is added to the rocks via microbial reduction of seawater sulfate. ⺠Under appropriate conditions microbial activity in the subsurface biosphere can affect the chemistry of the lower oceanic crust.
