UHCL : UHCL Researchers To Study Meteorites From Mars With Barrios Funding

Press release from University of Houston-Clear Lake:

July 6, 2021

Currently, Imrecke has been working in the areas of structural geology, petrology
and petrography. "I'm embarking on a new field, but I'm able to bring a lot of the
tools from my previous research into this," he said. "I'm researching planetary geology,
specifically the study of meteorites from Mars."

As a structural geologist, Imrecke has previously employed his knowledge to understand
the origin and evolution of mountain ranges. Structural geology, in its most basic
form, is about how rocks respond to stress.

"Some meteorites have experienced significant stress because they are ejected from
other bodies in the solar system," he said. "This is what I'm studying. I'm looking
at the changes the minerals have undergone as a result of the deformation that occurs
during ejection. We're looking at the petrography, the minerology, and the geochemistry
of those rocks."

He added that his research was being done in collaboration with the scientists at
the Lunar Planetary Institute, located very close to both Johnson Space Center and
the UH-Clear Lake campus.

"It's the development of this collaboration that will allow for more UHCL students
to get involved with planetary science projects," he said.

Imrecke said he would be completing his research with Ane Slabic, who is working toward
her Master of Science in Environmental Science with Specialization in Environmental Geology.

"I'll be analyzing the samples for this project," Slabic said. "The samples have all
been subjected to a variety of shock, from virtually no shock present to highly shocked
and complex samples. We have four samples, three from Mars and one from Earth, that
we will be investigating and we'll be finding out how shock affects the chemistry
of these samples by analyzing and interpreting their physical and chemical data."

The goal of collecting this data, Imrecke continued, is to get quantitative geochemical
analyses of phosphate minerals in meteorites. "It's useful for the broader planetary
geology community to have this data because not much is known about the shock effects
of the distribution of elements within those minerals," he said. "Interpretations
might be skewed in a way that isn't telling the full story about planetary processes."

He said the research would ultimately be published, and the primary purpose beyond
the work was to get seed money for further studies on this topic. "The Barrios funds
help get the ball rolling in a broader planetary geology focus that students can take
at UHCL," he said.
