A: Discrete and spaced cleavages, frequently interrupted at the outcrop scale, underlined by pink and dark seams of insoluble minerals in a meta-rhyodacite lava flow (western part of Tillet creek); B: Dissolution-schistosity plane underlined by insoluble minerals where cleavage becomes a stylolithic joints in a meta-rhyodacite lava flow from Tillet creek; C: Volcanic enclave in the core of pervasive disjunctive spaced cleavages in a meta-rhyodacite deposit from Tillet creek; D: Dissolution-schistosity planes and truncated volcanic enclave in a meta-rhyodacite deposit from Tillet creek; E: Disjunctive schistosity planes highlighting pressure-solution seams in a meta-rhyodacite lava flow from Rifflet creek. The black square indicates the location of the sample in Figure 7E; F: Photomicrographs of microstructures from schistose zones observed in thin sections using polarized and cross-polarized microscopy. Schistosity is underlined by oxides in a meta-rhyodacite lava flow from Rifflet creek. Red arrows highlight microstructures of dissolution at the grain boundary of a meta-pyroxene and a plagioclase volcanic phenocryst.
