Numerous pegmatite dikes are present on and near Cahuilla Mountain, chiefly within masses of tonalite and more basic intrusive rocks. Dikes on the south side of the mountain have yielded commercial feldspar and quartz, and several pegmatites on the east side and on Little Cahuilla Mountain to the northwest have been worked for lepidolite and gem tourmaline, beryl and spodumene.
