它检测什么。
| 材料 | 典型产出环境 | 可能的混淆因素 |
|---|---|---|
| Hydrothermal Core Complexes | Intrusive centers, volcanic calderas, and porphyry lithocaps | Extensive post-mineral volcanic cover |
| Structural Alteration Corridors | Regional faults, shear zones, and detachment systems | Quaternary colluvium in fault trenches |
方法
工作原理。
输入校准反射率，每个像元都对照公开参考库进行拟合。
District alteration clustering
Pulls spatial clusters of advanced argillic, phyllic and gossanous pixels out of contiguous scenes.
Leave-one-region-out calibration
Whole geological provinces are withheld during fitting, so a score cannot borrow its evidence from a neighbouring pixel in the same district.
Label permutation as a negative control
Discrimination is retested against randomised occurrence coordinates. A model that scores well on shuffled labels is measuring the sampling, not the ground.
Score generation with provenance
The output is a continuous district score carrying its model version, its input set and its interval. Expert-system features are deliberately kept out of it, so the two engines stay independent.
