Crustal fissuring on the crest of the southern East Pacific Rise at 17°15′–40′S

Creator:: Wright, Dawn J., Haymon, Rachel M., White, Scott M., and Macdonald, Ken C.
Abstract:: Fissure densities and widths have been mapped along the axial zone of the superfast spreading southern East Pacific Rise (EPR) at 17°15′–40′S with the near-bottom DSL-120 and Argo II imaging systems. We observe that the youngest lava flows (on a relative age scale) are sparsely fissured and that there is...
