WebAug 4, 2024 · Olivine is a major mineral in Earth’s mantle. Deformation microstructures such as CPOs are assumed to reflect the deformation conditions in the crust and mantle. Based on results of simple shear deformation experiments at high P–T conditions, olivine crystallographic fabrics have been divided into five types (A–E) [56,57,58]. These fabric ... WebThe crystal structures of the A n B n O 3n−2 homologues are formed by slicing the perovskite structure with (1̅01) p crystallographic shear (CS) planes. The shear planes remove a layer of oxygen atoms and displace the perovskite blocks with respect to each other by the 1/2[110] p vector. The CS planes introduce edge-sharing connections of ...
