Unraveling the dynamics of magmatic CO2 degassing at Mammoth Mountain, California
(Elservier, 2018)
The accumulation of magmatic CO2 beneath low-permeability barriers may lead to the formation of CO2-rich gas reservoirs within volcanic systems. Such accumulation is often evidenced by high surface CO2 emissions that ...
Inter-laboratory test for oxygen and hydrogen stable isotope analyses of geothermal fluids: Assessment of reservoir fluid compositions
(John Wiley & Sons, Ltd, 2018)
Rationale
Knowledge of the accuracy and precision for oxygen (δ18O values) and hydrogen (δ2H values) stable isotope analyses of geothermal fluid samples is important to understand geothermal reservoir processes, such as ...
Soil degassing at the Los Humeros geothermal field (Mexico)
(Elservier, 2018)
The Los Humeros geothermal field is the third most important producer of geothermal electricity (70 MW) in Mexico. Geothermal fluids are hosted in fractured andesitic lavas and mostly consist of high enthalpy steam with ...
REE fractionation during the gypsum crystallization in hyperacid sulphate-rich brine: The Poás Volcano crater lake (Costa Rica) exploited as laboratory
(Elservier, 2018)
The critical role of rare earth elements (Lanthanides plus Yttrium; hereafter REE) in high-tech technologies and consequently their increasing demand from the industry, in addition to the capability of REE to trace water–rock ...
Effects of reclaimed water discharge in the Maneadero coastal aquifer, Baja California, Mexico
(Elservier, 2018)
Since 2014, reclaimed water has been used for agricultural irrigation and it has been discharged on a riverbed of the Maneadero aquifer, Baja California, Mexico. To determine the effects of reclaimed water on groundwater ...
Paleomagnetism of Holocene lava flows from Los Humeros caldera, eastern Mexico: Discrimination of volcanic eruptions and their age dating
(Elservier, 2018)
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 ...
Robust estimation of temporal resistivity variations: Changes from the 2010 Mexicali, Mw 7.2 earthquake and first results of continuous monitoring
(Society of Exploration Geophysicists, 2018)
The magnetotelluric (MT) method is a well-known geophysical technique in tectonic and reservoir exploration studies. In recent years, several works have proven that the MT method is a valuable tool for monitoring fluid ...
The Los Humeros (Mexico) geothermal field model deduced from new geophysical and geological data
(Elservier, 2018)
The Los Humeros volcanic complex, a 21 × 15 km diameter caldera edifice nesting volcanic domes and a complex faulting structure, is located at the eastern edge of the Trans-mexican volcanic belt (TMVB). It is a young edifice ...
Reappraisal of Los Humeros Volcanic Complex by New U/Th Zircon and 40Ar/39Ar Dating: Implications for Greater Geothermal Potential
(Wiley Online Library, 2018)
Longevity and size of magmatic systems are fundamental factors for assessing the potential of a geothermal field. At Los Humeros volcanic complex (LHVC), the first caldera‐forming event was reported at 460 ± 40 ka. New ...
New method for initial composition determination of crystallized silicate melt inclusions
(Elservier, 2018)
Silicate melt inclusions (SMI) trapped in minerals and carried up to the surface by volcanism are routinely studied in order to determine the pre-eruptive volatile budgets of volcanic systems. The volatile contents of SMI ...
