Objectives
The
basic objective of the Department of Geosciences Graduate Program is to provide
students with a broad fundamental background in geosciences as well as an
in-depth emphasis in a particular specialty.
The
Master of Science degree (thesis option) is designed for students desiring
research experience in a specific area of the geosciences. This degree will
prepare the student for professional employment in the energy, mining, or
environmental industries or government, as well as those seeking a doctoral
degree. The Master of Science degrees (non-thesis options) are designed for
students who seek employment in the energy, mining, or environmental
industries, and the industrial application of Geospatial Information Sciences
(GIS).
The
Doctor of Philosophy degree in Geosciences emphasizes basic research in one of
the specialties in geosciences and is designed to prepare students for advanced
positions in the energy, environmental or mining professions in industry or
government, or for positions in academia.

Paleomagnetism and Rock Magnetsm Laboratory
The newly completed Paleomagnetism and Rock Magnetism laboratory at the
University of Texas at Dallas, including a low magnetic field induction space
designed and constructed by Dr. Gary Scott of Lodestar Magnetics, is about
2,600 sq feet in footprint, and includes an attached
sample preparation/wet chemistry laboratory, equipped with a fume hood, and an
attached meeting/office space area for graduate and undergraduate
students. The laboratory, to be
completed early in 2012, will include all non-magnetic furniture and cabinetry
installed by Dr. Gary Scott and colleagues in the low magnetic field
space. The workhorse instrument for all remanence measurements is a 2G Enterprises Model 760R
horizontal access, three measurement axis (DC SQUID) superconducting rock
magnetometer, equipped with DC SQUIDS and superinsulation. A fully automated specimen handling system is
interfaced with an on-line alternating field (AF) demagnetizer capable of
reaching peak inductions of 160 mT, allowing for
automated demagnetization of specimens.
We have initiated the purchase of a new, pulse-cooled magnetometer from
2G Enterprises, with anticipated delivery in early 2013. AGICO JR-5 and AGICO JR-6 spinner
magnetometers allow for the remanence measurements in
both automated and static mode. Thermal demagnetization is conducted using Shaw
(MMTD), and three ASC (TD48) furnaces, a Schonstedt
(TSD-1), as well as a home built large-volume, three heating zone furnace
capable of heating/cooling in an inert atmosphere. A large-volume furnace is capable of
conducting long-term, elevated temperature magnetic viscosity experiments in a
controlled atmosphere. The laboratory
includes two ASC impulse magnetizers, with the full range of coil sizes. Two home built impulse magnetizers capable of
peak DC induction of 1.3 T and 3.4 T and a horizontal Curie balance for
measuring saturation magnetization as a function of temperature in an inert
atmosphere. An additional, home built
impulse magnetizer, capable of reaching about 9 T, is currently being
tested. Two ASC D-2000 AF demagnetizers
provide peak field values of 200 mT and are capable
of imparting anhysteretic remanent
magnetization (ARM) and partial ARM with DC fields up to 1.0 mT. A D-Tech coil
interfaced with an externally tuned Schonstedt GSD 1
AF demagnetizer also allows for AF demagnetization and ARM acquisition. Chemical demagnetizations are carried out in
a fume hood environment in the laboratory.
The leaching and drying of specimens is carried out in a field-reduced
environment (less than 300 nT)
in the fume hood. Kappabridge
KLY-3S, KLY-4S, and MFK1-FA automated susceptibility systems allow bulk and
anisotropy of magnetic susceptibility measurements to be made in both static
and automated modes. The KLY-3S and
MFK1-FA susceptibility units are interfaced with a CS-4 furnace assembly for
measuring susceptibility as a function of temperature in an inert
atmosphere. The laboratory also has over
ten sets of mu-metal shields of different volumes and geometries, to provide
very low magnetic field environments for different purposes. We are equipped for all aspects of field
sampling and specimen preparation, including four complete sets of drilling
equipment and three dual bladed trim saws. An Olympus BX51TRF-5 transmitted
light/reflected light microscope, equipped with a dedicated DP72, 12.8 mp digital camera. A Princeton Instruments AGM/VSM, equipped
with a high temperature furnace assembly, acquired by the Physics Department in
late 2008, has been transferred to the Geosciences Department, and a space
remote from the Paleomagnetism Laboratory will house
the magnetometer and internal water chiller system. The Physics Department at UTD maintains a
Quantum Designs Magnetic Property Measurement System and this is available for
use by the PI and students. The UTD Paleomagnetism
Laboratory has dedicated field vehicle, a 2011 Toyota Tundra.

Graduate Certificate in Remote Sensing
The
Remote Sensing Certificate is supported by the Department of Geosciences and
the
The
American Society for Photogrammetry and Remote Sensing (1997) defined remote
sensing as the art, science, and technology of obtaining reliable information
about physical objects and the environment, through the process of recording,
measuring and interpreting imagery and digital representation of energy
patterns derived from non-contact sensor systems.
Remote
sensing is a powerful set of software and hardware, computer-based techniques
for extraction and presentation of information represented by raster and vector
spatial data acquired via non-contact sensors. It provides reliable and
cost-effective means of studying the environment for protection, natural
resources management and urban planning. Government and non-government
organizations continuously seek qualified professionals to use remote sensing
for a wide range of applications.
