接触双晶-
在绿柱石晶体的{0001}、{1010}、{1121}面上，普遍发育螺旋位错、束合螺旋位错、层错及接触双晶，它们共同构成了绿柱石晶体生长的主要台阶源。
On the crystal surfaces of the beryl crystal at { 0001 },{ 1010 },{ 1121 } occur universally screw dislocation , constriction screw dislocation , stacking fault , and contact twin that serve as the major step like source for the growth of beryl crystal .
