REGULARITIES OF INTERPENETRATION FOR CRYSTALS OF SYNTHETIC WOLFRAMITE REDEPOSITED AT HYDROTHERMAL CONDITIONS

摘要

Grown at hydrothermal conditions (450 deg C, 470 kg/cm~2 pressure) synthetic wolframite crystals form numerous regular intergrowths varying broadly by mutual orientation of individuals. A part of them (about 37 percent) is presented by simple twins of 2'/m' and mm'm' groups most of which weren't described in publications formerly. Structural factors play the major role in morphology of those intergrowths.
