The unequivocal global warming of the climate system and clear influence human activities underscore urgency addressing current challenge Earth's warming. Not only many ecosystems but whole Earth System is being affected, in some cases, knowledge about impact change remains limited. A good example this are cave pearls, which highly interesting due to their particular geochemical fingerprint also from perspective natural heritage.The mountain regions Catalan Pyrenees experiencing more...
Abstract The present study determined the mineralogy and thermal properties of kaolin from Acoculco (Puebla), at eastern Trans-Mexican Volcanic Belt compared it with nearby deposits Agua Blanca (Hidalgo) Huayacocotla (Veracruz). kaolins was by X-ray diffraction, infrared spectroscopy scanning electron microscopy. Thermal behaviour studied differential analysis, dilatometry hot-stage deposit is composed mainly kaolinite SiO 2 minerals. In case Huayacocotla, alunite abundant in places minor...
The tin-rich polymetallic epithermal deposit of Poopó, plausible Late Miocene age, is part the Bolivian Tin Belt. As an low sulfidation mineralisation, it represents a typological end-member within “family” tin deposits. emplacement mineralisation was controlled by regional fault zone that constitutes geological border between Altiplano and Eastern Andes Cordillera. In addition to Sn Ag, its economic interest resides in potential critical elements as In, Ga Ge. This paper provides first...
The Santa Fe mining district is located in the Central Andean tin belt of Bolivia and contains several Sn-Zn-Pb-Ag deposits. From economic point view, most important deposits are Japo, Morococala. Beyond traditional metal commodities, Tin Belt could become an exploration target for indium, owing to potential ore-bearing paragenesis with high concentrations this technology-critical element. In district, ore occurs as two main types: (a) Sn-rich cassiterite-quartz veins, (b) Zn-Pb-Ag veins...
We report the first results of a combined focused ion beam and high-resolution transmission electron microscopy (FIB/HRTEM) investigation zoned laurite (RuS2)-erlichmanite (OS2) in mantle-hosted chromitites. These platinum-group minerals form isolated inclusions (<50 µm across) within larger crystals unaltered chromite Ojén ultramafic massif (southern Spain). High-magnification (HMEM), high angle-annular dark field (HAADF) precession diffraction (PED) data revealed that microscale normal...
The Velardeña mining district is economically the most important of Durango state. ore deposits occur in different skarn zones developed within intrusive contact between Mesozoic limestones and Eocene granitic stocks dikes. are related to Santa María dike Reyna de Cobre porphyritic stock (separated from each other by 10 km). They as irregularly shaped replacement masses near have a paragenesis dominated calc-silicates sulfides. mineral assemblages show textures calcic clinopyroxene...
La zona geotérmica de Pathé (Hidalgo, México) presenta valores anómalos mercurio atmosférico. Las anomalías detectadas (Hg en el aire) coinciden espacialmente con zonas alteración argílica avanzada (antiguas minas caolín); éstas constituyen fuentes naturales emisiones dicho metal pesado, cuyo enriquecimiento geológico se debe a los procesos interacción agua-roca. Al tomar cuenta que esta indica antiguas condensación vapor, deduce Hg movilizó principalmente como gas y no puede descartar...
