The Geochemistry laboratory has a Kevex Omicron

Geology Department, UT El Paso
PACES Laboratory for Remote Sensing
PACES is a multi-disciplinary university remote sensing research center. It is housed in
the Geological Sciences, Computer Science, and Engineering buildings. The presence of
PACES on the U.S. - Mexico border affords an unique opportunity to address vital
environmental, ecological, and social issues resulting from the proximity of these two
great countries.
The Paces facility in the Geology Building has a complete suite of 5, 10 and 30 m SPOT,
TM and Digital photo-orthoquadrangles for almost the entire Border Region A suite of
approximately 35 Apple, IBM and UNIX computers are available loaded with ENVI,
Arc-Info, Arc-View, ER-Mapper GMT and other GIS and Remote sensing software.

Environmental Geochemistry
Electron microscope/microprobe-- is a fully automated Cameca SX-50 microprobe
with a full-time technician. It has X-ray mapping ability for quantitative analysis of
speices distributions in samples. A Rontec solid state EDS provides both qualitative and
quantitative EDS.
ICP-MS --an inductively coupled mass spectrometer and direct current plasma atomic
emission spectroscope. ICP-MS is a versatile, rapid and precise analytical technique that
provides a high quality multi-element and isotopic analysis package. The detection limit
for most elements is in the sub-parts per billion (ppb) range. For some elements it may lie
in the sub parts per trillion range.
The Geochemistry laboratory has a Kevex Omicron microfluorescence instrument that
accommodates 30-cm-long samples with detection limits of 10 ppm on elements from Na
to U.
Nikon polarizing microscopes with photographic capabilities for analysis of
minerals and rocks.
A fluid inclusion stage with both heating and chilling capabilities.
Sediment and Surface Processes Laboratory
Complete sediment particle sizing with sieve pipette and hydrometer analysis at
1/2 phi intervals.
Constant Heard Hydraulic Conductivity apparatus
Guelph Permeameter for in-situ Hydraulic conductivity of soils and surficial
X-Ray diffractometer,
Nikon research polarizing microscopes for mineral identification and
Current meter
Field equipment including, augurs, AMS hammer core sampler, stream sediment
sampler, soft sediment samplers for depths up to 8’ below the surface.
The most recent acquisition is the ASSET -- Adjustable Shear Stress Sediment
Erosion and Transport Flume
 Near-In-situ Erosion and Transport Measurement of up to 1-meter long cores.
