Environments
Eztlite is a very rare mineral that occurs in the oxidation zone associated with other
tellurium-bearing species
(Webmin).
Localities
At the type locality, the Moctezuma Mine, Moctezuma Municipality, Sonora, Mexico, eztlite and
cuzticite were found together in oxidised ore in a matrix of intensely
silicified and
brecciated rhyolite
vitrophyre
cemented by drusy quartz and carrying
pyrite and
tellurides. Both occur with various
iron oxides, emmonsite,
schmitterite, kuranakhite
and
pyrite
(AM 68.471, HOM).
