Charlie sedimentary basin 

(Cenozoic) 

(Beaufort Sea, Chukchi Sea, and adjacent area, unit Czs)

Consists chiefly of Cenozoic sedimentary rocks. Bathymetry and gravity modeling suggest that basin 
ranges from exceeding 2,200 m deep to the south to 3,000 m deep to the north where it merges with the 
Mendeleev Abyssal Plain and is underlain by oceanic or attenuated continental crust. Seismic-reflection 
data also indicate sedimentary prism in Charlie Basin is more than 2 km thick. REFERENCE: Hall, 1970
