Lithology and depositional settings of the terrigenous sediments along transform plate boundaries: Evidence from the early cretaceous Zhuravlevka terrane in Southern Sikhote Alin

An attempt was made to identify the source areas and depositional settings of the Berriasian-Albian sediments of the Zhuravlevka terrane based on a complex study of the structure and composition of the terrigenous rocks. These sediments are interpreted as formed in a basin related to the regime of the strikeslip transform plate boundaries with a minor volcanic contribution. The granite-metamorphic rocks of the mature continental crust were the main sources of detrital material transported into this basin. At the same time, the data suggest a significant contribution of fragments of the pre-Cretaceous active margin, including remnants of chert and ophiolite nappes of the accretionary wedge. The genetic features of the sediments indicate their formation on the shelf, the submarine continental slope, near its foot, and on the adjacent areas of the basin’s plain.
