The flanks of the ultraslow‐spreading Mid‐Cayman Spreading Center (MCSC) are characterized by domal massifs, or oceanic core complexes (OCCs). The most prominent of these, Mt. Dent, comprises lower‐crustal and upper‐mantle lithologies and hosts the V... Read More about Volcanic-tectonic structure of the Mt.
