| The aster index’s channel operation | Corresponding minerals and rock components | Usage instructions | |
|---|---|---|---|
| 1 | 12/13 | The base index is unusually good | Good |
| 2 | 15/13 | Rich siliceous rocks are unusually good | Good |
| 3 | 3/5 | The bauxite is unusually good | Better |
| 4 | 5/3 | The iron hat is abnormal, but the negative is abnormal | Bad, but negative |
| 5 | 4/2*2/3 | Iron anomaly is better | Better |
| 6 | 8/3 | Kaolin is unusually good | Better |
| 7 | 5*8/7*7 | The clay minerals are exceptionally good | Good |
