The plagioclase ranges from [[oligoclase]] to [[andesine]] and [[labradorite]], and is often very zoned. [[Sanidine]] occurs also in some dacites, and when abundant gives rise to rocks that form transitions to the rhyolites. The biotite is brown; the hornblende brown or greenish brown; and the augite is usually green.

The groundmass of these rocks is often microcrystalline, with a web of minute feldspars mixed with interstitial grains of quartz or [[tridymite]]; but in many dacites it is largely vitreous, while in others it is felsitic or cryptocrystalline. In hand specimen many of the hornblende and biotite dacites are grey or pale brown and yellow rocks with white feldspars, and black crystals of biotite and hornblende. Other dacites, especially augite and enstatite dacites, are darker colored.
