(a) Binary phase diagram of the solid solution series between albite and anorthite, the dashed line around the Huttenlocher gap is the speculated strain free boundary between and e1; (b) the metastable phase diagram showing the relation between and e-plagioclase as proposed by Jin et al. (2019), a transition zone eγ is added in the diagram representing the structure with weak and diffuse e-reflections. Liquidus and solidus lines, and the peristerite solvus is modified from Carpenter (1994). |
