Malinche, La

成層火山 · Mexico · 4461m

Malinche is located between the Popocatépetl-Iztaccíhuatl and Orizaba-Cofre de Perote volcanic ranges. The edifice is largely Pleistocene in age and is seen here in an aerial view from the SE. The canyons on the flanks are a result of glacial erosion. Holocene lahars from La Malinche associated with an eruption about 3,100 years ago reached the Puebla basin and affected precolumbian settlements.

地質学的概要

La Malinche is an eroded stratovolcano, cut by deep canyons, NE of the city of Puebla. It occupies an isolated position between the Popocatépetl-Iztaccíhuatl and Orizaba-Cofre de Perote volcanic ranges. Much of the andesitic-dacitic volcano was constructed during the Pleistocene, and the summit exhibits evidence of glacial erosion. Although relatively unstudied, research has identified Holocene tephra layers that originated from Volcán la Malinche. Several cones and explosion craters, at least one of Holocene age, are found on the flanks; one of the most prominent of these is the Xalapaxco maar complex on the lower ENE flank. Holocene lahars associated with an eruption about 3,100 years ago reached the Puebla basin and affected communities there.

La Malinche, also known as Matlalcueye or Malintzin, is an inactive volcano located in the states of Tlaxcala and Puebla in Mexico. Officially, its summit reaches 4,461 metres (14,636 ft) above sea level, though it is generally considered to be closer to 4,440 metres (14,567 ft), using GPS measurements. It is the highest peak in Tlaxcala, the fifth-highest in Puebla, the sixth-highest in Mexico, the 23rd-highest in North America, and the 252nd-highest in the world. Its height above nearby cities varies from 1,908 metres (6,260 ft) above Huamantla, 2,461 metres (8,074 ft) above Villa Vicente Guerrero, 2,221 metres (7,287 ft) above Tlaxcala, to 2,299 metres (7,543 ft) above Puebla. The summit is 22.4 kilometres (13.9 mi) from Tlaxcala, 28.3 kilometres (17.6 mi) from Puebla, and 118 kilometres (73 mi) from Mexico City. The climate is cold near the summit and mild on the lower slopes.
