Influence Of Chemical Composition And Water On The Bulk Modulus Of Pyrope, Shu Huang

FIU Electronic Theses and Dissertations

Garnets are major silicates from the upper mantle to the transition zone. Elastic properties of garnets are essential to interpret the variation of seismic velocities at different depths and construct a model of the Earth’s composition. Due to the chemical flexibility at octahedron sites of the crystal structures, garnets usually exist with multiple components and have many composition variations. Pyrope is an important member in the garnet group. Fe²⁺-Mg²⁺ substitution in pyrope is one of the common solid solutions. We have synthesized and measured three synthetic solid solutions samples (Py₈₃Alm₁₇, Py₅₄Alm …
