LUGIS
University laboratory supported by the Geophysical and Geological Institutes.
Its main analytical goal is quantitative determination of mayor and trace elements
of rocks and minerals as well as high precision measurements of isotopic relations.
In order to fulfill this goal, the laboratory has a set of laboratories and
facilities that involves several techniques such as mineral separation, ultra
pure chemical laboratories, X Rays fluorescence (Siemmens spectrometer) and
mass spectrometry (Finnigan and Micromass spectrometers). This facilities are
available to researchers from the National University involved in related projects
and as well to other national or foreign institutions.

ICP-MS
This Lab has a VGElemental mass spectrometer PQ3 and a preparation sample room
with pure air system (10,000 particles/m3). The analytical technique is able
to determine trace and ultra-trace (ppb and ppt) elements in geologic and other
materials (rocks, sediments, soils, water, etc.). The Lab gives service to Geophysics
Institute internal and external research projects.
Laboratory of Thermo-Luminescence
In this Lab it
is studied the thermo-luminescence phenomena applied to dating materials, based
on the radio isotopes 238U, 232Th and 40K and considering the cosmic contribution.
With this method several geologic materials can be dated such as sediments,
lava flows, paleodunes, paleosoils, as well as some archaeological materials
as pottery, ceramic figures and bricks. In the latest cases it can be used as
authenticity tests
