The Laramide Orogeny deformed<br />

the foreland basin of the<br />

Sevier fold-thrust belt into a<br />

high orogenic plateau with high<br />

relief during the Late Cretaceous<br />

through the Eocene epoch, Fan<br />

said. The Sevier orogeny was a<br />

mountain-building event that<br />

affected western North America<br />

from what is now Canada in the<br />

north to what is now Mexico in<br />

the south, and was caused by<br />

tectonic plate activity between<br />

<strong>14</strong>0 and 50 million years ago.<br />

The current model is too simple<br />

to explain the great duration of<br />

the Laramide Orogeny – around<br />

40 million years – and the internal<br />

connections among the regional<br />

tectonic units and<br />

processes in the western United<br />

States, Fan said.<br />

“We are combining multidisciplinary<br />

basin analysis – sedimentology,<br />

stratigraphy, isotope<br />

paleoaltimetry, and detrital geochemistry<br />

– and basement apatite<br />

fission track thermochronology<br />

to reconstruct the<br />

temporal and spatial patterns of<br />

Laramide uplift,” Fan said. This<br />

work has led to an accepted paper in the journal Tectonics.<br />

A<br />

fter earning a B.S. in Geology from Lanzhou University<br />

in China in 2000, Fan decided to begin graduate school.<br />

The summer before starting work on her master’s degree<br />

at Lanzhou, she got the chance to participate in a collaborative<br />

project between Lanzhou and the University of<br />

Arizona. The study’s goal was to understand the tectonic<br />

processes forming the high Tibetan Plateau by studying<br />

the sedimentary rocks preserved in topographic lows,<br />

called sedimentary basins, in northwestern China. She worked as a field assistant<br />

for two University of Arizona researchers over that summer and the<br />

next.<br />

“I learned from these two knowledgeable geologists way more than the<br />

help I could provide at that time,” she said. “I was particularly impressed by<br />

their broad ranges of interest in nature, their determination to pursue a multidisciplinary<br />

approach to solve problems, their diligent work habits, and<br />

their patience with students. They became my role models, and the experience<br />

shaped my professional track significantly.”<br />

After earning an M.S. from Lanzhou in 2003, she applied for and was accepted<br />

to the University of Arizona for further graduate work. She earned a<br />

master’s in Geoscience in 2005 and then began work on her Ph.D. in Geoscience.<br />

In the summer of 2009, she worked as an intern geologist with<br />

ExxonMobil in Houston. She completed her<br />

Ph.D. the following semester while also working<br />

as a lecturer at Arizona, then spent the next 18<br />

months as a postdoctoral fellow at the University<br />

of Wyoming. In early 2011, she interviewed<br />

for a faculty position at UT Arlington and was<br />

impressed with the diversity of the faculty and<br />

students. She started in August 2011 as an assistant<br />

professor.<br />

“Their diversity represents different perspectives<br />

to shape our campus culture,” she<br />

said. “When I was interviewed in the spring of<br />

2011, the minute I saw the diverse populations<br />

walking around the green campus in the warm<br />

early spring, I said to myself this<br />

is the place I would be very<br />

happy to be.”<br />

Fan’s<br />

students<br />

love working<br />

with her because<br />

she is supportive<br />

and<br />

eager to help<br />

them succeed.<br />

Ohood Al salem, a second-year<br />

master’s student in Fan’s lab, is<br />

studying the history of subsidence<br />

(the sinking of the<br />

Earth’s surface due to geologic<br />

causes) of the Fort Worth<br />

Basin, which was formed 280 to<br />

250 million years ago by the<br />

collision between the supercontinent<br />

Gondwana and Laurentia,<br />

a large, stable portion of<br />

continental craton (part of a<br />

continental lithosphere) which<br />

forms the ancient geological<br />

core of the North American<br />

continent.<br />

“The subsidence history of<br />

the Fort Worth Basin is not only<br />

important to the understanding<br />

of tectonic processes during the<br />

collision, but also to the maturation and migration of oil and gas in the basin,”<br />

Fan said.<br />

Al salem plans to complete her master’s degree this spring and then hopes<br />

to begin work on a doctoral degree, with Fan as her mentor.<br />

“Dr. Fan is the best mentor. She always offers help and support to her students,”<br />

Al salem said. “She is a very hard worker and very talented, which<br />

gives me the motivation to do my best in my research. That’s why I really<br />

want to do my Ph.D. with her. I believe our work together will lead to excellent<br />

scientific research.”<br />

Sara Ayyash, a first-year master’s student, is studying rock samples collected<br />

by Fan from the White River Formation near Douglas, Wyoming, to<br />

learn more about the paleoclimate and paleoenvironment during the late<br />

Eocene and early Oligocene epochs, approximately 34 million years ago.<br />

“Dr. Fan is extremely dedicated to her work and teaching,” Ayyash said.<br />

“You can tell that she truly enjoys learning new things or subjects that she is<br />

not familiar with. She puts a tremendous amount of effort into what she does,<br />

whether it’s teaching or research and it shows during lectures or when you<br />

speak with her.”<br />

Fan finds her work as a geoscientist fulfilling and enjoys taking the knowledge<br />

she has acquired and passing it on to her students and helping them as<br />

they embark on their careers.<br />

“Because research is the only way to advance knowledge created in the<br />

past, I feel excited about the role I am playing in advancing knowledge,” Fan<br />

said. “I enjoy passing knowledge along in a variety<br />

of ways to students, and spending time<br />

with students in the classroom, lab, and field in<br />

order to help them gain the skills to make geologic<br />

observations, interpretations, and discoveries.Geology<br />

offers me the opportunity to<br />

conduct fieldwork and examine the Earth with<br />

colleagues and students in the wilderness. Such<br />

experiences are very rewarding because we discover<br />

the beauty of nature that most people do<br />

not see and forge long-term relationships.<br />

“Doing geology research is sometimes challenging.<br />

However, once in a while, I discover<br />

something that takes my breath away.” n<br />

located in the Wind River Basin of Wyoming. Below, Fan shows Aragonitic freshwater<br />

bivalve fossils found in the early Eocene Wasatch Formation on the west side<br />

of the Powder River Basin of Wyoming. The oxygen isotope ratio of the fossil will be<br />

used to collect information regarding the paleoelevation of the mountains bounding<br />

the basin. Photos courtesy of Majie Fan.<br />
