International Journal of Speleology, 2016 Several caves of hydrothermal origin in crystalline limestones and metasomatic silicites were investigated in the central zone of the Štiavnica stratovolcano, Štiavnické vrchy Mountains, central Slovakia. Evidence of hydrothermal origin includes irregular spherical cave morphology sculptured by ascending thermal water, occurrence of large calcite ...

Assisted-hydrothermal Synthesis and Characterization of Flower-like ZnO Nanostructures [PDF]
Published in Advanced Science Letters vol. 5, 2012, pp. 283, 2012 Flower-like nanostructures formed by ZnO nanorods were synthesized and deposited on seeded silicon and glass substrates by a hexamethylenetetramine (HMTA) - assisted hydrothermal method at low temperature (90 oC) with methenamine ((CH3)6N4), as surfactant and catalyst. The substrates were seeded with ZnO nanoparticles.

Phase-evolution in Co-Sb System: CoSb3 Hydrothermal Synthesis [PDF]
arXiv, 2018 Nanostructure CoSb3 samples were synthesized via hydrothermal technique along with different routes to study the phaseevolution in Co-Sb system. X-ray diffraction (XRD) explored to study the phase evolution in Co-Sb system via. Special emphasis on rietveld refinement and scanning electron microscope (SEM) were evaluated to study morphology of the ...

Petrology of hydrothermal metasomatism of intra-ore dolerite dikes of mesothermal gold deposits
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 There is a necessity of working up the geology-genetic theory of hydrothermal gold deposit formation instead of the four hypotheses excepting one another: granitogene, basaltogene, metamorphogene, polygene. The principal aim of the study: substantiation of goldisolating faculty of basaltic magmatism - causing and ensuring ore-forming geologic processes.
