The shallow structure of Los Humeros and Las Derrumbadas geothermal fields, Mexico
Geothermics, 1987Abstract Los Humeros caldera and Las Derrumbadas rhyolitic domes located in the State of Puebla (Mexico) are being extensively studied by Comision Federal de Electricidad (CFE) to assess the geothermal potential of that area. Both geothermal sites have been locally studied with geological, geochemical and geophysical methods.

Hydrothermal alteration and fluid inclusion geothermometry of los humeros geothermal field, Mexico
Geothermics, 1989Abstract The Los Humeros geothermal field, located in Puebla State, Mexico, occurs in a caldera; drillholes to 3000 m depth encountered a sequence of Quaternary lavas and pyroclastic rocks that range in composition from rhyolite to basalt but are dominantly andesitic. These rest upon the local basement comprising limestone and siltstone of Cretaceous

Alkali and alkaline earth element geochemistry of Los Humeros Caldera, Puebla, Mexico
Journal of Volcanology and Geothermal Research, 1984Abstract Results of the measurements of alkali (K, Rb and Cs) and alkaline earth (Ba and Sr) elements on seven pre-caldera and twenty post-caldera samples of Los Humeros volcanics (Pliocene to Recent) are described. These data are interpreted in terms of the known solid-liquid partition coefficients.

Geochemistry of boron in fluids of Los Humeros and Los Azufres hydrothermal systems, Mexico.
2010Separated water from geothermal wells of high-temperature geothermal fields Los Humeros and Los Azufres in Mexico are unusually rich in boron. According to the isotopic composition, boron in both fields has magmatic origin. Since the Los Humeros fluids, in contrast to Los Azufres, do not show any correlation between B and Cl and have Cl/B ?

Geochemical evidence for a lithospheric source for magmas from Los Humeros caldera, Puebla, Mexico
Chemical Geology, 2000Abstract This study reports new geochemical and Sr–Nd–Pb radiogenic isotope data on hy-normative Quaternary basaltic to rhyolitic volcanic rocks as well as two samples of Mesozoic to Palaeozoic intrusive igneous rocks from Los Humeros caldera (LHC), located in the eastern part of the Mexican Volcanic Belt (MVB).
