Geochemistry of Los Humeros Caldera, Puebla, Mexico
Bulletin Volcanologique, 1982Geochemistry of Pliocene to recent volcanic rocks from Los Humeros caldera (19°30′ N – 19°50′ N and 97°15° W – 97°35′ W) in East-Central mexico is described. The volcanic rocks from this area seem to represent both alkali and high-alumina basalt series, or both calcalkaline and high-K calc-alkaline sequences.

Gravity study of Los Humeros caldera complex, Mexico: Structure and associated geothermal system
Journal of Volcanology and Geothermal Research, 1992Abstract Los Humeros caldera lies in the eastern portion of the Trans-Mexican Volcanic Belt. A geothermal system is associated with this silicic caldera. The volcano-sedimentary products of the caldera itself rest on a basement of calcareous rocks and granitic intrusives.

Abstract We explored applications (including limitations) of Gauss's theorem to the study of silicic calderas. First it enables us to determine the mass deficiency from calderas. Mass deficiency itself has also other potential applications. It enables to make qualitative comparisons between calderas. We can use the mass deficiency to test, in a quick

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.

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).

Abstract The Cuicuiltic Member (CM) at Los Humeros Caldera, eastern Mexican Volcanic Belt is a Holocene (6.4 ka B.P.) succession of alternated fallout deposits of contrasting composition (trachydacite pumice and basaltic andesite scoria). The CM covers approximately 250 km2 on its proximal facies and its thickness ranges from 1.5 m to 8.0 m.

Geothermics, 1990
A simulation of the temperature field underlying Los Humeros caldera is obtained through numerical solution of the energy-conservation equation for a conductive heat flow process. The up-date information on geological, geochemical, geophysical and geochronological studies is used to estimate the parameters of the internal structure of the caldera.
