Figure 7

Trench graben with deformed sedimentary section. Section of high-resolution seismic line HD34B (Figure 1). The interpretation is based on the major features of Nakamura et al. (2013). Black dashed lines are thrust faults that sole into the décollement. The décollement is located above the chert boundary and within the sediment column in the graben. Light blue is the sediment column, units 1 and 2. Green region is unit 3. Dark blue region and dashed line marks the top portion of the igneous crust. Black solid lines are normal faults that offset the igneous crust.
