由绿柱石晶体中的线缺陷 (螺旋位错 )、面缺陷 (层错、双晶 )及点缺陷 (空位、包裹体 )的协同作用 ,是导致四川平武扁平板状绿柱石晶体形成的主要原因

• The formation of the flat tabular beryl crystal in Sichuan Province is attributed mainly to the synergy of the linear defects (screw dislocation),face defects (stacking fault and twining) and point defects (vacancy and inclusion) in the beryl crystal.
