▼a The thermal conductivity of minerals in Earth's lowermost mantle is important for the thermal and chemical evolution of Earth. In the thermal boundary layer separating the core and mantle, the bulk thermal conductivity helps determine the heat f |

▼a In this dissertation, I build on a new method to measure thermal conductivity at high pressures and temperatures using continuous wave laser heating in the diamond anvil cell and apply it to pressure induced phase transitions. I test the method |

▼a I use the method developed for ionic salts and apply it to the mantle mineral, ferropericlase, (Mg,Fe)O, over the pressure range of 22 GPa to 61 GPa. This range of pressure includes the reported spin transition of octahedrally coordinated iron, |

▼a Combining new ferropericlase thermal conductivity measurements with those of bridgmanite, and accounting for the spin transition, an updated thermal conductivity profile for the mantle can be calculated. The spin transition reduction has only a |

▼a The thermal conductivity depth dependence of ferropericlase and bridgmanite using the methods in this dissertation result in a CMB bulk thermal conductivity of 5.2 W/mK. Accounting for uncertainty in the thickness and temperature change across t |

▼a In a separate study, I use an analogous application of the heat equation to model the mass transport of sediment on hillslopes. Hillslope processes are important for understanding how surface landforms evolve over time. The application of linear |
