Background:
The Huitepec lava dome lies immediately west of the city of San Cristóbal de las Casas. The hornblende-andesitic dome has a height of about 520 m and was the source of ash-flow deposits, which crop out about 5 km NW of San Cristobal. These products are generally gray in color, with a phaneritic texture and coarse grains of plagioclase, pyroxene, and amphibole (Mora et al., 2007). The base of the dome has a mean diameter of 5.18 km, covering an area of about 21.2 km2 (Mora et al., 2007). A K-Ar date of about 850,000 years was obtained from the dome. In general, Huitepec dates to about 0.85-1.95 Ma (Mora et al., 2007). Huitepec's composition, like that of other eruptive centers in the Chiapanecan Volcanic Arc, is mostly intermediate, calc-alkaline (Mora et al., 2007).---
