Cation stacking faults in magnesium germanate spinel

Widely extended, cation stacking faults in experimentally deformed Mg₂GeO₄ spinel have been studied using transmission electron microscopy (TEM). The faults lie on {110} planes. The displacement vector is of the form (frac{1}{4}leftlangle {1bar 10} rightrangle ) and is normal to the fault plane. The partial dislocations which bound the stacking fault have colinear Burgers vectors of the form (frac{1}{4}leftlangle {1bar 10} rightrangle ) which are normal to the fault plane.
