Nearly all the Earth's interior is inaccessible to direct observation, making it necessary to study the Earth's internal dynamics through forward or inverse models that rely on indirect measurements taken at or near the surface. In recent years, the amount and variety of data available for such models have expanded dramatically, leading to a corresponding rise in the use of numerical models for interpretation. Tomographic images of the Earth's interior, along with reconstructions of past plate motions, are critical components in many Earth science studies. However, the uncertainties inherent in these models are rarely acknowledged or examined in depth. In this work, we gain new insights into the Earth's interior and its dynamics by conducting an objective analysis of these models, with a focus on exploring and accounting for their uncertainties and biases. We analyze tomographic images to clarify their geodynamic interpretations, particularly in distinguishing between buoyancies caused by thermal versus compositional variations. We then employ the plate reconstruction model, Tomopac, which integrates updates from seismic tomography and mantle convection models, to improve our understanding of intra-oceanic subduction zones. We assess how updates in intra-oceanic subduction zones-derived from seismic tomography and mantle convection models-enhance our understanding of the deep carbon cycle and Earth's climate transitions, as well as the prediction of future porphyry systems. We integrate plate tectonic subduction models with machine learning techniques to create prospectivity maps for copper mineralization. This approach highlights the potential of our method in advancing global mineral exploration.
