1868 F. von Richthofen in Mem. Calif. Acad. Sci. 1 ii. 16 The name ‘Nevadite’ is derived from that of the State of Nevada, where these rocks have been first met with in larger accumulations... Nevadite contains crystals of quartz in large production.

1888 J. J. H. Teall Brit. Petrogr. 75 The typical nevadites, however, are not granitic, but trachytic in texture.

1932 A. Johannsen Descr. Petrogr. Igneous Rocks II. 274 Nevadite is the name given by von Richthofen to certain rocks from Nevada and adjacent states, which show large, well-formed crystals of quartz, feldspar, biotite, and hornblende in a small amount of groundmass.

1968 Canad. Mineralogist 9 478 Silver ores at Morey occur as kryptothermal fracture fillings cutting a nevadite intrusive.

1991 Geochem. Internat. 28 vii. 137 In the Dukat gold-argentite deposit, there are sheets of Albian rhyolites, subvolcanic nevadite bodies, and granites, which form a single volcano-plutonic association.
