The Zaozigou gold deposit, situated in Gansu Province within the West Qinling orogenic belt, is classified as a super-large gold deposit. In the exploration of mineralization processes, numerous factors pose challenges for traditional identification methods. This study employs numerical simulation techniques to investigate factors that are challenging to discern through conventional methodologies in the formation of the Zaozigou gold deposit mineralization system. We aim to utilize multi-field coupling, integrating thermodynamics and fluid mechanics, to replicate the intricate movement of ore-bearing fluids. The research uncovers the mineralization patterns of the Zaozigou gold deposit. By constructing a two-dimensional model and examining the interplay of time, space, materials, and evolution, we pinpoint areas of abnormal temperature and normal pressure within the fluid, where the spatial distribution of S2− correlates with known mineralization patterns. Numerical simulations demonstrate that the migration of ore-bearing fluids, influenced by thermal flow fields and pressure dynamics, can lead to mineral concentration in regions exhibiting pronounced barotropic stress anomalies. These zones boast favorable mineralization conditions, elucidating disparities in mineralization between the northeastern and southwestern flanks of the fault-fold structure within the mining field. The outcomes of this investigation introduce a novel approach for advancing hidden ore prospecting efforts in the Zaozigou region.

“…The metal deposits found in the region are all located inside or at the edge of the low resistivity range, reflecting the relationship of them. In addition, a small-scale conductor body C6 appears at this depth, and its surface location is the Chating copper-gold mine [34], [35]. There are two conductors (C1 and C2) on the west side and east side of the Zhouwang Fault (ZWF).…”

“…Its top depth is about 1 km, and the bottom depth is about 6 km with a resistivity value less than 10Ω•m. C6 is located directly below the newly discovered Chating copper-gold deposit in the study area, reflecting the location of the mineralized body and the deep source of the ore body [34], [35]. There is a continuous low resistivity distribution near the surface of the JNF.…”

We have implemented a magnetotelluric observation in the Nanling-Xuancheng Ore Concentration Area within the Middle-lower Yangtze River Metallogenic Belts. The magnetotelluric data with 0.001-1000 s period was collected at 843 distinct sites, and all components are handled in the 3-D inversion of the observed dataset. We present the first detailed 3-D resistivity structure beneath the overlying sediment strata of the Nanling-Xuancheng Ore Concentration Area. The shallow parts of the inverted resistivity model fit well with surface geological information and the mineral deposit distribution, while the deep parts suggest a bulk of conductors exist beneath the southern boundary of the Xuancheng Basin. The presence of deep conductors implies an intense deformation and broken structure within this region. Moreover, the comparison with regional geological information, seismic reflection, and gravity data further strengthen this understanding. The study of the 3-D electrical structure is of particular importance for further exploration and research for this region and provides a reference for geophysical prospecting in other areas of the Middle-lower Yangtze River Metallogenic Belts.

“…Geochemical sampling environments include water and soil samples (undercover areas), stream sediment samples and rock samples (rock outcrop areas and core-drilling) environments. These studies by using modelling geochemical anomalies, based on the type of sampling at the study area, could lead to the identification of geochemical halos formed at the surface of the deposit and also mineralisation on the surface (surface sampling) or lead to the identification of mineralisation zones at depth (borehole sampling) (Hezarkhani and Ghannadpour 2015a; Hu et al 2020).…”
