Compositional variations in tourmalines from peraluminous rocks of the Dipilto Granitic Batholith, Eastern Chortis Terrane, Nicaragua: tracers of magmatic to hydrothermal evolution
Popis výsledku v původním jazyce
The granitoids of the Dipilto Batholith in northern Nicaragua range in composition from amphibole?biotite tonalite to cordierite?biotite and biotite granite. The petrographic and geochemical features indicate hybrid origin for the metaluminous granodiorite and tonalite (El Paraiso Suite). Dominant peraluminous granites (leucogranite dykes, Yumpali and La Piedra suites) represent a typical product of fractional crystallization of crust-derived melts.Tourmaline occurs as rare mineral in peraluminous granites of the Yumpali Suite (randomly distributed grains and quartz?tourmaline nodules), but is very common in the younger leucogranite, pegmatite dykes and hydrothermal veins. Chemical variations (mainly XFe and F) in tourmaline as well as in biotite are consistent with magmatic differentiation processes in granites and pegmatites. The presence of quartz?tourmaline hydrothermal veins indicates involvement of B-rich post-magmatic hydrothermal fluids at the final stage of the Dipilto Batholi
