Pachuca Range
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
[edit | edit source]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
[edit | edit source]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
[edit | edit source]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]
