Abstract:

The formation of the Dayingezhuang gold deposit involves the coupled effects of tectonic deformation，pore-fluid transport，heat transfer，and hydrogeochemical reactions.In this paper，FLAC3D nume-rical simulation software and modern mineralization rate concept were used to carry out numerical simulation of force-heat-fluid-chemical coupling of Dayingezhuang gold deposit，so as to explore the controlling effect of fracture structure，bulk deformation，and chemical process coupling on the emplacement of gold orebody.The simulation results demonstrate the following findings： From the perspective of physical process，the steep-slow transition and its local undulation zones along the Zhaoping fault tend to develop larger volume strains with differences of up to 1% compared to the surrounding rocks.This uneven strain distribution leads to the formation of uneven ore-holding spaces and pore pressure variation distribution.Significantly differences between high values of positive and negative pore pressure gradients are observed near the zones with large volume strains，while the differences in other zones are less notable.From the perspective of chemical process，mineralizing fluids tend to converge and stagnate at sites with high volume strain during their migration from the deep to the shallow parts.This convergence of mineralizing fluids leads to a greater precipitation of gold orebodies （mineralization rate less than 0），indicating the occurrence of intense water-rock reactions.In contrast，the areas where the mineralizing fluids don’t converge exhibit a predominance of positive mineralization rate dis-tribution，suggesting the absence of significant gold orebody precipitation.Furthermore，the ROC curve analysis with an AUC value of 0.815 provides quantitative evidence of the strong correlation between the mineralization rate and known gold orebodies，suggesting that this coupling of multiple physical-chemical processes at the same sites may be a key factor governing the formation of Dayingezhuang gold deposit. Based on these observations，it can be inferred that the deep-seated regions of Dayingezhuang deposit hold considerable mineralization potential.
