have TEM micrographs about magnesium near [11-23] zone axis, and the Weak Beam Dark Field (WBDF) micrographs for g=10-11 and g=10-10 show the dislocations but at different areas. How can I know the dislocation types (<a>, <c> or <c+a>) under the following three cases? 

1. Dislocations appear at g=10-11 but not at g=10-10;

2. Dislocations appear at g=10-10 but not at g=10-11;

3. Dislocations appear at both g=10-11 and g=10-10.
