[2] Kuna Crest granodiorite forms most of the outer part of the Tuolumne Intrusive Suite, on the edges.

[7][8] Kuna Crest Granodiorite makes up most of the outer part of the Tuolumne Intrusive Suite.

Magnetite crystals and those of titanite in the Kuna Crest granodiorite are usually euhedral, and occur in aggregates.

The distinguishing feature of the Kuna Crest granodiorite is the presence of anhedral crystals of hornblende abounding in inclusions of the other minerals.

These have all axes of the same length (1–3 mm), and are anhedral, and show no evidence of significant post-crystallization strain.

The absence of well-balanced, 120° facial angles between the minerals indicates that no major readjustment of the grain boundaries took place after the magma had crystallized.

[3] Estimates from petrographic observation of average mineral proportion of non-layered rocks of Kuna Crest granodiorite follows: Of the Tuolumne Intrusive Suite, in Kuna Crest granodiorite, the proportion of the mafic minerals is greatest, at 21%.
