News 2007

The Annual QCL IA Meeting and Field Trip was a fun time and a chance to look at some cool rocks. There was certainly no complaining about the scenery. Vishal Maharaj led the first day of the trip and Nysha Chaderton led the days on Barbados. 11/19/07

The QCL IA Annual Meeting will be held in Port of Spain Trinidad and Barbados the week of November 11-17. A series of talks will be presented on the worldwide research underway in the IA on Monday November 12, followed by a four day field trip to Trinidad and Barbados to view the paralic to shelf edge deposits of the Pliocene on Trinidad, and the Eocene Scotland Formation coarse-grained turbidites of Barbados. The field trip will be co-led by Dr. Ron Steel, Nysha Chaderton, Vishal Maharaj and Ariana Osman. So far, ten of our fourteen member companies plan to attend. 10/26/07

N. Chaderton examines the highly folded Scotland units on Barbados. Although highly structured in some parts of the island, the Scotland shows great exposure and lateral continuity in its type area of Barbados' Scotland District.

Vishal Maharaj

Vishal Maharaj presented a poster at the annual JSG Geology Foundation Meeting held at the Austin Grand Hyatt on November 18 titled "Seismic Geomorphology of Atoka Channels, Fort Worth Basin, Texas".

The Summer Crew

Lesli and students

The summer allowed some of the graduate researchers to get a jump on the fall. Vishal Maharaj (far left) is examining channel architecture in the Atoka Formation. Tricia Alvarez (middle) is examining the seismic geomorphology of latest Pleistocene sequences on the shelf in Trinidad using 10,000 sq km of 3D seismic. Tiffany Hedayati (far right), split her time between the field and the lab looking at the El Vado shelf sequence in the San Juan Basin of New Mexico. 9/4/07

Tiffany HedayatiLesli Wood

Tiffany Hedayati and Lesli Wood recently returned from field work in the eastern edge of the San Juan Basin, where they sought out the elusive El Vado Sandstone, the topic of Tiffany’s masters thesis research. The El Vado is a shelf sand within the Mancos Shale. 8/28/07

Lesli Wood

Lesli Wood taught a field camp module in the Sego Sandstone in June. Thirty-two undergraduates attended the one week module run in eastern Utah where they examined the stratal relationships between falling stage tidal bar complexes, incised valley fills and distributary channeling, as well as the associated storm influenced shelf system.

QCLIA student researchers attended the GSTT Technical Conference held in Port of Spain, Trinidad. Nysha Chaderton presented her research on coarse-grained turbidites of the Scotland Formation, Barbados. Ariana Osman, previous UT graduate, presented her research in the Morne L'Enfer Group of southern Trinidad. Ariana and Nysha will both be co-leading the QCL IA field trip in November on Trinidad and Barbados, to be held in conjunction with the QCL IA Annual Meeting November 11-16. 7/23/07

Lorena Moscardelli was awarded the doctorate of science passing her oral examination and defense of her dissertation research on April 10th. Dr. Moscardelli has taken a position with the Bureau of Economic Geology in the Jackson School of Geosciences as a Research Associate and will continue to be involved in the QCL IA research program as well as other research at the JSG. Congratulations Dr. Moscardelli! 5/3/07

Chad Weisenburger, Julie Maher and Terence Campbell will all be awarded a Masters of Science from the Jackson School of Geosciences in a ceremony to be held May 19 at the UT Campus. Chad has accepted an offer of employment from EOG. Julie has accepted an offer of employment from ExxonMobil. Terence has accepted an offer of employment from bpTrinidad.

We wish them well, thank them for all their hard work toward the goals of the QCL IA and congratulate them on their success. 5/3/07


Nysha Chaderton is off for the summer squeezing in TWO internships. The first part of the summer will be spent with Shell in their Houston office. The second part of the summer will be spent with BHP in their Houston office. Nysha is finishing up the second year of a three year, post-master's Ph.D. in research into coarse-grained deep water deposits of Barbados and the surrounding regions.
