To reach the ambitious goals and targets of UN 2030 Agenda for Sustainable Development it is compulsory to pay special attention those strategies that arise from local communities. In this contribution we present a comparative study on initiatives pursuing development through sustainable use geoheritage, two territories central Mexico: (a) Tlalpujahua-El Oro former mining district (Michoacán State Mexico), (b) Comarca Minera UNESCO Global Geopark (Hidalgo state). Both cases are...
This article reports the characterization of two High Purity Germanium detectors performed by extracting and comparing their efficiencies using experimental data Monte Carlo simulations. The were calculated for pointlike $\gamma$-ray sources as well extended calibration sources. Characteristics such energy linearity, resolution, full peak are reported from measurements on surface laboratories. will be deployed in a assay facility that located first underground laboratory Mexico, Laboratorio...
A boiling model that considers the increase of salinity due to steam loss and uses a combined density coexisting vapor liquid phases was applied fluid inclusion data from Los Azufres geothermal zone an Eocene epithermal vein Taxco. These case studies are taken as examples active fossil hydrothermal systems, respectively. In high temperatures homogenization (> 300 °C) commonly attained at depths between 1500 2000 m whereas values above 2.0 wt.% NaCl eq. occur within upper ~ 500 system,...
This paper explores the prospect of CMOS devices to assay lead in drinking water, using calorimetry. Lead occurs together with traces radioisotopes, e.g., 210Pb, producing g-emissions energies ranging from 10 keV several 100 when they decay; this range is detectable silicon sensors. In we test a camera (OXFORD INSTRUMENTS Neo 5.5) for its general performance as detector X-rays and low energy g-rays assess sensitivity relative World Health Organization upper limit on water. Energies 6 60 are...
La Comarca Minera de Hidalgo (México) es desde mayo 2017 un Geoparque Mundial la UNESCO; dicha denominación se justifica por geopatrimonio relevancia internacional que incluye: (a) el sistema epitermal (Ag‒Au) clase mundial Pachuca‒Real del Monte; (b) localidad tipo tridimita y cristobalita; (c) los basaltos con disyunción columnar Huasca Ocampo (conocidos como Prismas Basálticos Santa María Regla); (d) patrimonio industrial minero, comprende vestigios prehispánicos haciendas beneficio...
Abstract The emergence and implementation of the geopark concept bring into discussion topic areas with previous designations (i.e. biosphere reserves, national parks) open up debate on challenges to aspiring new ones (e.g. heritage stones, IUGS geological sites). When put context, ‘layering’ designations, whether they are partial or total, international, need harmonize documents, management plans teams; advancements given in dissonance normative detrimental such goals but happen, as...

With these comments we question the article by Velázquez García & Lazcano Benítez [Pasos, 21(1), 23‑36. 2023], which addresses in a disjointed and confusing way some aspects of designation management UNESCO Global Geopark Comarca Minera, Hidalgo (Mexico). Although title announces possibility opening discussion on tourism territory, manuscript does not develop this idea instead deviates towards value judgments unfounded accusations. Because it is based an erroneous theoretical corpus...
Para evaluar la percepción social de los paisajes Hidalgo, se desarrolló un cuestionario electrónico que aplicó en dos instituciones enseñanza media superior del Geoparque ‘Comarca Minera’. El tamaño muestra fue 197 individuos (116 corresponden a una escuela rural y 81 urbana). sitio preferido por su paisaje es el geositio emblemático ‘Prismas Basálticos’. Éste aparece también como más preocupa conservación. Huasca Ocampo, Mineral Monte Chico son las entidades preferidas; tres municipios...
Isotope identification is a recurrent problem in gamma spectroscopy with high purity germanium detectors. In this work, new strategies are introduced to facilitate type of analysis. Five criteria used identify the parent isotopes making query on large database gamma-lines from multitude producing an output list whose entries sorted so that highest chance being present sample placed at top. A metric evaluate performance different and compare them. Two found be superior than others: one based...
The World Health Organisation (WHO) presents an upper limit for lead in drinking water of 10 parts per billion ppb. Typically, to reach this level sensitivity, expensive metrology is required. To increase the sensitivity low cost devices, paper explores prospects using a volume reduction technique boiled sample doped with Lead-210 ($^{210}Pb$), as means solute's concentration. $^{210}$Pb radioactive isotope and its concentration can be measured e.g. High Purity Germanium (HPGe) detectors at...
