Examples of MSH plagioclase crystals with textural features akin to resorption experiments. (a) Multiple dissolution surfaces (arrows) associated with rounded edges and roughened surfaces, some of which are associated with melt inclusions (MI). Note the small resorbed crystal that attached to the large plagioclase crystal after one of the last recorded resorption events (‘IG’). (b) Two intergrown plagioclase crystals with various dissolution surfaces and a shared outer rim. The triangular shaped crystal next to the intergrown crystals bears striking resemblance to the experimental texture in Fig. 9a. (c) A crystal with two distinct resorbed cores with roughened surfaces (C1 and C2), similar to the experimental texture in Fig. 10c.
