The Role of Reducing Conditions in Building Mercury

Camille Cartier and Bernard J. Wood

The interior structure of Mercury. The relatively thick crust (ca. 40 km) overlies the comparatively thin mantle (ca. 400 km). A hypothetical iron sulfide layer might occur at the core-mantle boundary, overlying the liquid outer core (radius of ca. 2,000 km). The innermost part of Mercury is made of a solid core suggested to have a radius < 1,000 km. Copyright © Mark a. garliCk
