The Pachuca Range (Sierra de Pachuca) is a mountain range in the Sierra Madre Oriental of central Mexico, in the state of Hidalgo. [1]
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.
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]
The surface rocks are volcanics beginning with Miocene andesites and micro diorites 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]
