Its habit plane can change from the a (100) to the b (\(\bar 3\)10), the c (\(\bar 2\)10), and the d (\(\bar 1\)10) (path 1) or to the e (30\(\bar 1\)), the f (20\(\bar 1\)), and the g (10\(\bar 1\)) (path 2). The schematic of two paths and the cross point are shown on the right side h. The different habit planes are marked by the purple, green, and blue, respectively.
