Identifying minerals with
the ASD TerraSpec Halo
Manufactured by Netherlands-based PANalytical B.V., the
hand-held ASD TerraSpec Halo provides field or mine geologists
with rapid identification of key pathfinder minerals. The 4.5-lb
(2.5 kg) instrument has a full range, near infrared spectrometer
that takes a non-destructive reading and displays on-screen
results of up to four minerals in a mineral sample, making it use
-
ful for prospecting, logging drill core or grade control at mines.
The device also features GPS capability and the operator can
even make a "geotag" and record audio notes. This data can be
downloaded into a computer when back in the field camp or
office.
As many mineral deposits are characterized by an alteration
halo, the TerraSpec Halo can quickly define the size and geometry
of a halo to home in on the deposit, saving both time and money
that would be spent prospecting and drilling. The battery-pow

ered TerraSpec Halo comes with a custom-designed holster and
provides readouts in American English, Spanish and simplified
Chinese. Another feature of note is the extensive spectral mineral
library with multiple examples of minerals.

countries with North American outlets in St. Laurent, Quebec
and Westborough, Massachusetts
