Figure 4

Type 3 foliated semi-nephrite (sample TW04), (a) Polished sample of foliated semi-nephrite, (b) EBSD map showing dominance of strongly aligned tremolite crystals (red on map) that comprise the main schistosity. Also present are elongate domains (e.g. domain e) that contain tremolite crystals with a wider range of shape and crystallographic orientations than displayed by the main fabric, (c) Contoured pole figures (one point per grain) showing data from the main fabric. Tremolite laths and needles have their c-axes (001) strongly aligned parallel to the foliation and lineation, (d) Pole figures showing all data from domain e, (e) Line profiles of cumulative misorientation through 7 tremolite crystals shown in part b, (f) Internal misorientation (= grain orientation spread, GOS) of each grain shown in the EBSD map in part b.
