Table T4. Normalization factors for calculation of relative mineral abundance using bulk powder X-ray diffraction analysis. (See table note.)
| Affected mineral in standard mixture: |
Normalization factors | |||
|---|---|---|---|---|
| Total clay | Quartz | Plagioclase | Calcite | |
| Influencing mineral: | ||||
| Total clay | 9.8956702E–03 | –1.5889532E–04 | –2.8855808E–04 | –7.3842803E–04 |
| Quartz | –4.7221169E–05 | 5.8782392E–04 | –4.7869325E–05 | –3.1098843E–05 |
| Plagioclase | 7.2794763E–04 | –4.2840613E–05 | 1.3719777E–03 | –3.6005495E–05 |
| Calcite | 4.2042411E–05 | 3.3021188E–06 | –4.1329499E–06 | 1.3071455E–03 |
Note: Singular value decomposition was used to compute factors, following Fisher and Underwood (1995).
