Tectonic history of Ulleung basin margin, East Sea (Sea of Japan)
A geologic history analysis of an exploratory well drilled on the southern margin of the Ulleung back-arc basin, East Sea (western part of the Sea of Japan) reveals that tectonic force and sedimentary loading played a major role in the subsidence of the paleo-Ulleung basin where a thick clastic sequence was deposited during the Neogene. Initial subsidence was most likely caused by a tectonic force related to the back-arc rifting and spreading associated with convergent processes. The southern margin underwent regional deformation (uplift, faulting, and folding) toward the late Miocene. This event was probably due to back-arc deformation caused by changes both in plate motion and in subduction mode at the convergent zones.
