International Geology Review, 2009
We present results of our simulation study of the effects of the depth (top of the magma chamber at 5–10 km) and volume (1000–1400 km3) of the primary heat source beneath the Los Humeros caldera. The thermal gradient in the vicinity of the magma chamber calculated from the temperature excess (difference between the simulated and the initial ...

Los Humeros caldera is a Quaternary volcanic structure located on the eastern portion of the Mexican volcanic belt. Geothermal exploration, including well drilling, is presently carried out; geophysical surveys over the 200 km’ structure include aeromagnetometry, gravimetry, tellurics, self-potential, resistivity soundings (Schlumberger).

Magma genesis and chamber processes at Los Humeros caldera, Mexico—Nd and Sr isotope data
Nature, 1983The Mexican volcanic belt (MVB), a roughly east–west structure, consists of many late Tertiary and Quaternary cindercones, domes, calderas and stratovolcanoes1,2. Los Humeros caldera (approximately 19°40′ N latitude, 97°25′ W longitude) lies on the northeastern part of the MVB where the belt overlaps with another major volcanic province, the Eastern ...

Abstract Los Humeros caldera in eastern Mexico has been formed since about 164 ka, with important effusive activity during the upper Holocene, which covered more than 100 km2 with lava. Two lava flows were 14C dated at 2692-1950 cal BCE and 1117-930 cal BCE, but the detailed succession of eruptions is yet unknown even though the interest for volcanic

Geological Society of America Bulletin, 2012
Los Humeros is the largest caldera volcano in the Mexican volcanic belt. Its second largest caldera-forming eruption, the ca. 0.1 Ma Zaragoza eruption, is recorded by two Plinian pumice-fall layers and a zoned intra-Plinian ignimbrite. Diverse pumice types within the ignimbrite provide insights about the way that different magmas within a single ...
