Makarov sedimentary basin 

(Cenozoic) 

(Sea of Okhotsk (near Sakhalin Island), unit Czs)

Consists chiefly of Miocene to Quaternary sedimentary rocks with thickness of up to 4 km. Seismic data 
indicate sedimentary rocks occur in two units, an upper subhorizontal unit, and a lower, more deformed 
unit that fills irregularities in the surface of acoustic basement. The basin overlaps the suture separating the 
Academy of Sciences and Institute of Oceanology collages. REFERENCES: Baboshina and others, 1984;
