Introduction
[2] In modern tectonic studies, the East Asian
continental margin is treated as a collision-accretion feature,
produced by the complex combination, in space and time, of
accretion and collision processes, as well as of the transform fault movements of both individual terrains and their assemblages

[3] One of the key positions in the structure of the
continental margin is occupied by the terrains of the accretion
prisms of different ages (Figure 1), which recorded the time and
mechanisms of the continental growth. The subduction, turbidite,
and island-arc terranes, associated with them, produced the
lateral series of structural features and allow one to reconstruct
the old continent-ocean transition zones. In the modern structural
pattern of the continental margin, these lateral rock series are
seen to have been disturbed significantly by the late Mesozoic
large size strike-slip movements along the margin,
and by the Cenozoic destructive pull-apart and
strike-slip movements which operated during the opening of the
Sea of Japan and the Sea of Okhotsk basins.
[4] To a lesser extent these movements complicated the
structural features of the Late Mesozoic-Cenozoic Hokkaido-Sakhalin
fold system, represented by the structural features of the
Sakhalin and Hokkaido islands, a connecting link between them
being South Sakhalin. Over the whole length of this fold system,
its eastern segments, including those of South Sakhalin, represent
a complex zone of the connection of the oceanic structural
features and those of the continental margin, providing good
objects for reconstructing the evolution of the transitional zone.
[5] Presented in this paper are the new data available for the
geology and tectonics of Southeast Sakhalin, which add to the
knowledge of the structure and tectonic history of the Hokkaido-Sakhalin
accretion-type fold system and offer new tectonic
reconstructions for the East Asia continental margin for
Cretaceous-Paleogene time.
