FIELD: mining.
SUBSTANCE: samples are taken of natural object. Taken samples are mineralogically analysed. Rare metal deposit availability is determined, using loparite depositions as deposit indicator. Besides rock chip samples, representing main facies on the territory of the intrusive massif, are taken. Mineral composition of samples is lithologically studied. In case of loparite presence in samples, the grain character is determined. As among grains loparite of automorphic shape is available, prospectivity of rare metal deposits search in this massif is judged.
EFFECT: increase of received results reliability.
