Abstract
The Wenyu gold deposit, Henan Province, is located in the southern part of the Xiaoqinling gold belt. It is controlled by a brittle-ductile shear zone and hosted in the Taihua Group metamorphic complex. The crosscutting relationships and mineral assemblages suggest that the ore forming process includes the early, middle and late stages. Three types of fluid inclusions (FIs) in the quartz of Wenyu gold deposit are identified as CO2-H2O, pure CO2, and H2O-solution. The early-stage quartz contains primary pure CO2 and CO2-H2O with homogenization temperatures clustering at 290~330℃ and the salinity of 1.02%~9.59% NaCleqv. Vapor bubbles are composed of CO2+H2O±N2±CH4. The middle-stage quartz trapped all the three types of FIs. The CO2-H2O FIs is the majority one, and the homogenization temperatures of CO2-H2O and H2O-solution FIs cluster at 250~290℃, and the salinities are 0.02%~12.81% NaCleqv. Fluid inclusions in late-stage quartz are H2O-solution with low homogenization temperatures (114~239℃) and low salinities (4.18%~8.95% NaCleqv). Minimum trapping pressures estimated from CO2-H2O inclusions are 130~178MPa and 85~150MPa for early and middle stages, respectively, corresponding to the ore-forming depth of 4.7~6.5km and 3.1~5.5km, respectively. In general, the ore fluids in the early and middle stages are characterized by meso- to hypothermal, CO2-rich and low salinity, which are considered as the nature of metamorphic fluids, whereas the late-stage fluids are low temperature, low salinity and CO2-poor. Fluid immiscibility caused gold precipitation in the middle-stage. The ore-forming fluid-system of the Wenyu gold deposit is the same to that of the orogenic-type. The Wenyu gold deposit is a mesozonal to epizonal orogenic gold deposit.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
