Southern EPR-Segment I

Southern EPR at 18.5°S (Segment I)

열극 분화구 · Undersea Features · 2600m (해저)

Black smoker vents emitting low-chlorinity fluids at 374°C were photographed at the "RM28" site at 18°26’S on Segment I of the Southern East Pacific Rise in November 1994 from the Japanese submersible Shinkai 6500. The narrow axial crest of Segment I of the Southern East Pacific Rise in some places is less than 50 m wide. The largest lava flow field in this area is the Animal Farm flow, named after a thriving low-temperature hydrothermal site discovered during a 1993 submersible expedition. · 사진: Image courtesy of NOAA Vents Program, 1994 (www.pmel.noaa.gov/vents/chemistry/images/).

지질학적 요약

The narrow axial crest of Segment I of the Southern East Pacific Rise in some places is less than 50 m wide. An axial dome is located along the southern part of the segment. The largest lava flow field in this segment is the Animal Farm flow, named after a thriving low-temperature hydrothermal site discovered during a submersible expedition in 1993. The Animal Farm lava flow was dated by magnetic paleointensity measurements at about 1880-1950 CE, and older flows were dated by similar techniques to the 17th and 19th centuries.
