The Pachuca Range (Sierra de Pachuca) is a mountain range in the Sierra Madre Oriental of central Mexico, in the state of Hidalgo.^[1]

History and etymology

The mountains were named Pachoacan (Pachyohcan) (place of hay) by the native Nahuatl speakers,^[2] although there are also a variety of other theories about the origin and meaning of the name.^[3] The earliest recorded settlement name is "Pachuquillo" a diminutive of Pachuca.^[2] Later the town of Pachuca de Soto and the municipality were named Pachuca.

Geography

The Pachucas form the northeastern boundary of Mezquital Valley.^[4] They trend northwest–southeast^[4] and run about 45 kilometres (28 mi) from Cerro Monte Noble in the north to Real del Monte at the southeast.^[5]

Geology

The surface rocks are volcanics beginning with Miocene andesites and microdiorites followed by alkaline basalts.^[6]^[7]

The rocks are highly mineralized and contain ores of gold, silver, lead zinc, mercury and other metals.^[7]^[8] The mining districts of Pachuca and Real del Monte lie on opposite sides of the Pachucas.^[7]
