Thermophysical Dynamics of Ore-forming Fluids in Heat Ore Deposits: Implications for Ore-formation Processes

Abstract

In heat ore deposits, the role of ore-forming fluids in geological processes, notably in the genesis and evolution of such deposits, is pivotal. These fluids predominantly encompass aqueous solutions, molten magma, and various gaseous phases, each demonstrating intricate thermophysical attributes and dynamic behaviours within the high-temperature and pressure conditions of the deep crust. Contemporary methodologies and models, constrained by their specificity to certain environments and elements, often fall short in offering a holistic perspective or forecasting capabilities. To bridge this deficiency, a comprehensive set of mathematical models and equations has been constructed in the present study, subsequently facilitating an in-depth examination of the thermophysical properties of ore-forming fluids and the associated ore-formation processes in heat ore deposits. The research is segmented into three primary components: the derivation of thermal and solute diffusion equations; the establishment of mass and energy conservation equations; and the formulation of a solute transfer equation. This integrative approach not merely furnishes a robust theoretical foundation for decoding the intricacies of ore-forming fluids in heat ore deposits but also bears considerable scientific and pragmatic implications.
