Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

open access: yesTerra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Estimating the depth and evolution of intrusions at resurgent calderas: Los Humeros (Mexico) [PDF]

open access: yesSolid Earth, 2020
Resurgent calderas are excellent targets for geothermal exploration, as they are associated with the shallow emplacement of magma, resulting in widespread and long-lasting hydrothermal activity.

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

Difracción de rayos X en la caracterización de especies arcillosas: un caso de aplicación en el pozo H29 del Campo de Los Humeros, Pue.

open access: yesGeofísica Internacional, 1993
Los filosilicatos formados como producto de la alteración hidrotermal en zonas geotérmicas activas son de gran interés, ya que su ocurrencia es un reflejo de la temperatura y presión del medio.

Scaling of internal joint distance in the elbow of small‐ to medium‐sized mammals: Implications for range of motion analyses

open access: yesJournal of Anatomy, Volume 248, Issue 6, Page 950-971, June 2026.
We investigated the internal joint distances (IJDs) of the humero‐ulnar and humero‐radial joint, within a sample of 15 small‐ to medium‐sized mammals and report isometric results. We also found that joint poses had no effect on IJDs and that IJDs scale isometrically within small species.

Análisis geoquímico-isotópico de las especies carbónicas del fluido geotérmico de los Humeros, Puebla, México

open access: yesGeofísica Internacional, 1993
Evidencias geoquímicas muestran que los fluidos del yacimiento de Los Humeros presentan un exceso de vapor con mezcla de un fluido agresivo proveniente de un segundo yacimiento y sólo los pozos someros como el H-1 no son afectados por tal fenómeno. Datos

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

New remains of Titanochelon richardi (Testudines, Testudinidae) from the Upper Miocene of the Vallès‐Penedès Basin: taxonomic and phylogenetic implications

open access: yesPapers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract The alpha‐taxonomy of continental giant tortoises (Testudinidae, Titanochelon) from the European Neogene is far from settled, which has implications for inferring their phylogenetic relationships. The diagnosis of the type species (Titanochelon bolivari) is dubious because it considered Titanochelon richardi as a junior subjective synonym ...

Mosaic morphology in Podocnemididae revealed by a new turtle from the Middle Miocene La Venta Biome, Colombia

open access: yesPapers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract A new genus and species of podocnemidid turtle, Shakiremys colombiana, is described here from the Middle Miocene La Venta Biome, located in south‐central Colombia. The new taxon is represented by two specimens: one consisting of a complete skull and articulated shell, and the other of an articulated shell only.
