Geochemical mass balances, supported by mineral characterization and whole-rock
elemental analyses, were used to decipher the alteration paragenesis and to understand the …

Most of the volcanic rocks in the Acoculco geothermal system (AGS), near to the surface
manifestations, are intensively altered. Thirty‐four surface volcanic rocks and five rocks from …

To investigate the effects of hydrothermal alteration on the chemistry of volcanic rocks, we
analyzed the whole rock chemical composition (major and trace elements, including rare …

The Acoculco geothermal system records two major hydrothermal events (prograde skarn
overlapped by retrograde/” epithermal” to geothermal stages) in association with pre …

This work presents a review of the geological, hydrogeochemical, and mineralogical
information related to the Los Azufres geothermal field, along with new isotopic data from …

The Los Humeros geothermal system is composed of more than 2200 m of Quaternary
altered volcanic rocks and an underlying Cretaceous sedimentary sequence. The low …

Detailed mineralogical analyses in areas with surface hydrothermal alteration zones
associated with recent volcanism (< 1 Ma) in the Central Andean Volcanic Zone could …

The hydrothermal deposit of Ixtacamaxtitlán (Puebla, Mexico) is made up by a succession,
from bottom to top, of quartzveins and stockwork enclosed in a porphyritic subvolcanic body …

Abstract In Northwestern Mexico, the Miocene basins that disrupted the Sierra Madre
Occidental Province are filled with sandstones and conglomerates (the Báucarit Formation) …

Thermal waters in the Southern Volcanic Zone (SVZ) of Chile between 36°–41° S were
studied using major and selected trace element relationships to characterize their …
