Zeolites are silica and aluminum hydrated tectosilicates. They have a
high cation exchange capacity (CEC) that makes them useful as
fertilizers and soil amendments in agriculture. They have a cage-like
structure that makes them useful in water softeners and filters. They
are also used as catalysts in the pharmaceutical and petrochemical
Zeolites form in both volcanic and sedimentary rocks. The most
commonly mined zeolites include chabazite, clinoptilolite and
Field identification and mineral mapping during zeolite exploration
can be done using the oreXpress high resolution/high sensitivity NIR
field spectrometer. The oreXpress covers the UV/VIS/NIR spectral
range from 350-2500nm. It is portable and lightweight with an all solid
state photodiode array design with no movable optical parts for
reliable rugged field use.
Take spectral measurements in the field with a contact probe for fast
and accurate mineral mapping. Two lithium-ion batteries provide
portable scanning power for the unit and the contact probe with its
built-in light source. There are two contact probe options: our
standard 10 mm mineral contact probe and the 3mm Miniprobe for
focusing on smaller sample features.
Optional EZ-ID mineral identification software matches to known
samples from two libraries of 1500 spectra and more than 600
minerals. Geologists can use EZ-ID's match regions and score tables
to unmix minerals within samples for better identification of dominant
EZ-ID has known samples of clinoptilolite in its libraries with
absorption features at 630nm, 1425nm, 1915nm and 2430nm. The
libraries also contain samples for mordenite.
In addition to matching to known samples, EZ-ID allows a geologist to
build their own libraries while scanning known samples and include
all metadata relevant to those samples such as location, operator,
sample type, color, and other descriptive details. The result is a
project/site specific library of known samples.
EZ-ID mineral identification software matches your samples against two libraries of
more than 600 mineral spectra. Here you see a sample of clinoptilolite (blue) matched
to a library sample (red).
