Regional scale rifting and subsidence in the vicinity of Iheya-Minor Ridge, the middle Okinawa Trough: Cruise results of KM17-12C

Shallow sub-seafloor structure in the vicinity of Iheya-Minor Ridge was acquired using Sub-Bottom Profiler equipped on R/V Kaimei in KM17-12C cruise. Normal faults and downward warping stratification indicate regional subsidence of the studied area. The profiles also suggest local-scale compression...

Summary:Shallow sub-seafloor structure in the vicinity of Iheya-Minor Ridge was acquired using Sub-Bottom Profiler equipped on R/V Kaimei in KM17-12C cruise. Normal faults and downward warping stratification indicate regional subsidence of the studied area. The profiles also suggest local-scale compression folds that may associate with the intrusive volcanism of the ridge.
