Role of Peritectic Biotite for the Chemical and Mechanical

Fine-grained mafic enclaves (<1 vol %) are commonly present within the WAT and, locally, form enclave swarms parallel to the external zone with concentrations reaching >50 vol % (Blundy, &, Sparks, 1992).They are systematically associated with hornblende- and biotite-rich accumulation zones texturally identical to the host tonalitic body, an …

Biotite crystals in barren granodiorite are observed as euhedral to subhedral phenocrysts with regular margins. Petrographic studies revealed local oxidation along the cleavage, and the local partial alteration is secondary chlorite in primary biotite. Biotite crystals in granular barren granodiorite are brown and reddish-brown (Fig. 5 c, d).
