Abstract
Abstract The Dayingezhuang gold deposit is located in the central part of the Zhaoping Fault Zone, which is one of the most important gold‐hosting faults in the Jiaodong gold province of China. Dayingezhuang is a typical large‐scale shear zone‐hosted disseminated gold deposit with superimposed silver mineralization. Fluid inclusion (FI) petrography and microthermometry, and analysis of oxygen and hydrogen isotopes for fluid inclusions were conducted to determine the characteristics of the ore‐forming fluids and the processes of silver mineralization. Microthermometry data of FI indicated that ore‐forming fluids are characterized by low salinity and low density. Homogenization pressures of FI are estimated at 20 × 10 5 –220 × 10 5 Pa. The change in ore‐forming fluids from K 2 SO 4 type to NaCl type indicates the superposition of two hydrothermal mineralizing events. Ore‐forming fluids were dominated by magmatic components in the early mineralization period, and affected by meteoric waters in the late period. Gold may have been transported as Au‐S or Au‐Cl complexes, whereas silver was transported as Ag‐Cl complexes. Early fluid boiling and later fluid mixing are thought to be two of the main factors causing the deposition and superimposing of gold and silver to form the large 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
