| These tests are: the cathodoluminescence, fluorescence with the rays-X and the Uv-Visible spectroscopy and the infra-red spectroscopy. |
| Internal zoning and grain characteristics were mapped by microphotography and cathodoluminescence imaging. |
| Specimens were observed using transmitted light, polarized light, reflected light under oil, and cathodoluminescence. |
| Internal textures were imaged using backscattered electrons and cathodoluminescence. |
| Mineralization was studied in core using cathodoluminescence, transmitted and reflected light microscopy and fluid inclusion microthermometry. |
| Samples were analyzed petrographically and by cathodoluminescence to establish a paragenetic sequence, and individual phases drilled for geochemical analysis. |
