In case, when it becomes difficult to determine minerals due to physical and mechanical reaction and alteration of outer nature, following techniques are used additionally:

• Use of reference minerals
• Microchemical tests using chemical reagents
• Crystallo-optical methods using polarized transmitted light
• Luminescence light method
• X-ray diffraction method
• Optic emission spectral analysis
