Quantification of the Spectral Variability of Ore-Bearing Granodiorite under Supervised and Semisupervised Conditions: An Upscaling Approach
Table 1
The main mineralogical compounds that were measured in laboratory. The standard deviation (sd) and the relative standard deviation (rsd) were also included to examine the variance in the mineralogical measurements.
