Thermodynamic properties of tetrahedrite-tennantites: constraints on the interdependence of the ag*cu, fe*zn, cu*fe, and as*sb exchange reactionsExperimental constraints, petrologic studies, and theoretical analysis suggest that, energetically, tetrahedrite-tennantite sulfosalts are remarkably well behaved multisite reciprocal solutions....
Electron paramagnetic resonance and optical absorption spectral studies on tennantite and tetrahedrite mineralsThe behaviour of transition metal ions in tetrahedrite and in tennantite have been studied by electron paramagnetic resonance and optical absorption spectroscopy in the UV-Vis and NIR regions....
Tetrahedrite and tennantite: evaluation of thermodynamic data and phase eouilibriaABSTRAcT Tetrahedrite and tennantite are extremely common in a variety of ore deposits, but the genetic information they record is difficult to decipher because of the limited under-standing of their phase...
Deposit, erzgebirge, germany. iii. first indication of complete miscibility between tennantite and girauditeGiraudite and hakite, and their more widespread S-dominant analogues, tennantite and tetrahedrite, are locally abundant, but overall rare species in the Niederschlema–Alberoda uranium deposit in the Erzgebirge of Germany....
