Below are a series of images exported from the 2023_Textured_Earth_Structure.skp computer-aided-drafting (CAD) model built using SketchUp Pro 2020 software. Mantle structures are based on Moulik and Ekstrom's (2014) whole-mantle, shear-wave velocity reference model including global coverage of shear-wave velocity values at 13 different levels between 100 km and 2890 km depths (Herman, 2022). I'm studying plate drift , the structural form of mantle plumes and cold, dense, material bodies that mantle the liquid outer core. I'm hypothetically calling the process of gradual material accretion onto the outer core as core plating. email me at gcherman56@yahoo.com.
