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 the designation and management of the UNESCO Global Geopark Comarca Minera, Hidalgo (Mexico). Although the title of the article announces the possibility of opening a discussion on tourism in the territory, the manuscript does not develop this idea and instead deviates towards value judgments and unfounded accusations. Because it is based on an erroneous theoretical corpus and lacks a reproducible methodology, the article could only be considered as a text of opinion. Moreover, Velázquez García & Lazcano Benítez outline a political and administrative chaos to which they attribute the failure of a potentially transformative project (“Ruta Arque‑ ológica Minera”, in the municipality of Pachuca de Soto). The Comarca Minera UNESCO Global Geopark is not unaffected by this situation, but thanks to the fact that it has been managed as an essentially academic project —developed by universities hand in hand with the communities (ejidos)— it has achieved significant successes that allowed it to be revalidated by UNESCO for a new four‑year period (2022‑2025).
Mineral chemistry of In-bearing minerals in the Santa Fe mining district, Bolivia
(National Geology and Mining Service, 2018) Abigail Jiménez–Franco; Pura Alfonso; Carles Canet; Juan Elvys Trujillo
The Santa Fe mining district is located in the Central Andean tin belt of Bolivia and contains several Sn-Zn-Pb-Ag deposits. From the economic point of view, the most important deposits of the district are Japo, Santa Fe and Morococala. Beyond the traditional metal commodities, the Central Andean Tin Belt could become an exploration target for indium, owing to the potential of the ore-bearing paragenesis with high concentrations of this technology-critical element. In the Santa Fe mining district, the ore occurs as two main types: (a) Sn-rich cassiterite-quartz veins, and (b) Zn-Pb-Ag veins with sphalerite, galena and stannite mineral phases. The In content in igneous rocks is between 1.5 and 2.5 ppm, whereas in the ore concentrate it attains up to 200 ppm. The 1,000×In/Zn ratio in concentrate ranges from 25 up to 4,000. Exceptionally high In values were found in sakuraiite from Morococala deposit (2.03 wt%). Sakuraiite in this deposit shows evidences for a link between stannite and kësterite trend of solid solutions. There is a noteworthy exploration potential for strategic metals in this district and even in similar deposits elsewhere in the Central Andean tin belt.
