Petrologic and geochemic features of the ore-containing substratum in hydrothermal gold deposits. P. 1. Petrology of the near-ore metasomatism

Известия Томского политехнического университета: Инжиниринг георесурсов, 2016
The relevance of the research is caused by the necessity to correct and elaborate on geological (metallogenical) component of the hydrothermal gold deposits formation theory within the framework of which the conflicting ideas about ore-formation ...

Tourmaline ⁴⁰Ar/³⁹Ar chronology of tourmaline-rich rocks from Central Iberia dates the main Variscan deformation phases

Geologica Acta, 2009
During crustal thickening, metapelites taken to depth release boron-bearing hydrothermal fluids because of progressive heating and dehydration. These fluids swiftly percolate upwards, especially if the crust is being actively deformed, to form tourmaline
